Humidity Sensor – Humidity to Frequency Output

This sensor board provides frequency output as per relative humidity value. The project is based on a unique capacitive cell, this relative humidity sensor is designed for high volume, cost-sensitive applications such as office automation, automotive cabin air control, home appliances, and industrial process control systems. It is also useful in all applications where humidity compensation is needed. The circuit is built using a low-cost NE555 timer as an astable generator, humidity sensor MK1 acts as a variable capacitor and is connected to the TRIG and THRES pin. Pin 7 is used as a short circuit pin for resistor R3. The HS1101LF equivalent capacitor is charged through R2, R3, and PR1 is set the threshold voltage (approximately 0.67Vcc) and discharged through R2 only to the trigger level (approximately 0.33Vcc) since R3 is shortened to the ground by pin 7. Since the charge and discharge of the sensor run through two different resistors, R2 and R3, the duty cycle is determined by the following formulas.

Duty cycle Calculation:

t_high = C@%RH*(R2+R3)*ln2
t_low= C@%RH*R2*ln2
F = 1/(t_high+t_low) = 1/(C@%RH*(R3+2*R2)*ln2)
Output duty cycle = t_high*F = R2/(R3+2*R2)

Refer to the lookup table below for humidity RH (%) VS frequency output. PR1 Trimmer pot provided to calibrate the fine output.

paperd.ink: Simple and Elegant E-paper development board

Posted on 24 June, 20213 May, 2022 by DM

E-paper or e-ink displays mimic the appearance of ink on paper, making it suitable for reading. These displays provide a wider viewing angle, and the e-paper display is easily visible in direct sunlight without the image appearing to fade. Most e-paper displays today are based on ESP32 WiFi with touchscreens and additional Bluetooth connectivity. Earlier, we have covered a similar e-ink display Inkplate 6PLUS. It is an open-source, based on Wi-Fi-enabled ESP32 board with a recycled 6.0-inch e-paper display featuring a touchscreen.

Rohit & Prasad, two young engineers from India, recently introduced paperd.ink. It is a 4.2 inch simple and elegant e-paper development board. The classic e-paper display allows you to focus on your work peacefully. The board can display calendars, weather, to-do lists, notifications, images, art pieces, and much more. The design is open-source, which means you can customize its enclosure, integrate it with custom APIs and tailor it according to your needs.

paperd.ink display specifications:

ESP32-WROOM-32 module
FCC/CE certified WiFi & Bluetooth for connectivity
4.2″ monochrome e-paper display
<20uA current consumption in sleep mode
CP2104 USB-UART converter onboard for programming
MicroSD card slot for storing images, files, etc
Piezo buzzer for notifications and alerts
4x tactile buttons for user input
Battery charger circuit to keep it completely wireless
Extension header for interfacing and expanding capabilities

ESP32-WROOM-32 microcontroller is at the core of this e-paper development board. It is one of the most popular microcontrollers as it is a complete standalone system. It can be programmed using the micro USB connection and is supported by Arduino, Micropython, and ESP-IDF. It can interface with other systems to provide WiFi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces. It features a dual-core processor with an adjustable CPU clock frequency from 80 MHz to 240 MHz. The chip has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power. It has 520 KB of on-chip SRAM and an integrated 4 MB SPI flash memory. It supports WiFi 802.11 b/g/n protocols as well as Bluetooth v4.2 BR/EDR and BLE.

The 4.2-inch monochrome e-paper display has a resolution of 400 x 300 (DPI: 120). It supports the SPI interface. The e-paper display features a full refresh of 3s and has added support for a partial refresh.

In the latest version of paperd.ink, the LDO is changed to XC6220B331MR-G, which has a lower quiescent current. These revisions helped reduce the sleep current. The sleep current is currently well below 20uA. You can charge it in a single go and use it for months.

The board consists of the following external interfaces:

UART, SPI, and I2C so you can add external sensors and modules. This makes the board extendable.
8 I/O for controlling any output and receiving any input.
Disable ESP32 module using ESP_EN pin to reduce power consumption.
Disable the entire board using the LDO_EN pin and have virtually no current consumed by the board.

The PCB measures 92.1 x 78.1 mm, and the 3D-printed enclosure is 98 x 82 x 16 mm. The enclosure comes with a stand and is 3D printed using the SLA process in ABS white material. The display is available with enclosure and without enclosure.

The KiCAD design files (schematics/PCB layout), STEP files for the 3D enclosure, and an Arduino sample are available on Github.

About the crowdfunding campaign

Engineers Prasad Khake and Rohit Gujarathi launched the crowdfunding campaign on Indiegogo for Paperd.ink and evinced interests from multiple industry stakeholders for pioneering India’s first e-paper display platform with open-source technology. The news raised over 25 percent of the intended capital needs and went viral on niche communities including Hacker News, subreddits, Facebook groups and received orders from the United States, Brazil, Israel, India, Germany, France, Spain, and United Kingdom.

Researchers from the University of Chicago developed a foldable haptic actuator for mixed reality applications

Posted on 24 June, 2021 by DM

Actuators are the moving part of a device that controls the mechanism of a system. A simple example of an actuator is the opening of a valve. With this simple example of a solenoidal valve, we can understand that an actuator (or, in other words, a part that performs a movement in a specific direction) needs a control signal along with the source of energy. The control signals are relatively low energy in the form of voltage or current. The control system can be software-based, a human, or any other input. Combining actuators with mixed reality applications can open up a whole new world of interaction. Mixed reality refers to combining real and virtual worlds for producing new environments and visualizations.

With mixed reality, physical and digital objects can co-exist and interact in real-time. A team of researchers from the University of Chicago recently published an article on a foldable haptic actuator for rendering touch in Mixed Reality. This device is developed to provide an interactive environment where the user can touch a virtual object. The device provides feedback to mixed reality (MR) environments by pressing against the user’s fingerpad when a user touches a virtual object. It provides low-frequency vibrations on the finger contact points. The device is called Touch&Fold, and it is designed to fit on a user’s fingernail. When the device is not in use (when the user is touching real-world objects), the device folds back on top of the user’s nail.

Touch&Fold features a linear resonant actuator that allows rendering not only touch contacts (i.e., pressure) but also textures (i.e., vibrations). The device is wireless and self-contained. It measures only 24×24×41 mm and weighs 9.5 g. The actuation takes only 92 milliseconds.

“Many haptic devices on the market enable users to interact with objects in the virtual world, such as controllers and gloves, but none provides the ability to interact with objects in both worlds and feel them at the same time.”

The Touch&Fold works with Microsoft HoloLens 2 headwear which displays the mixed reality environment and tracks the user’s hand in real-time with the help of depth cameras. The folding mechanism is achieved by a DC motor. The control loop consists of a force sensor FSR 400 and a photo-interrupter SG-105F. The force sensor doubles as a feedback signal for fine-tuning the amount of pressure applied to the fingerpad.

Source: https://dl.acm.org/doi/10.1145/3411764.3445099

The researchers with their study demonstrate how the haptic device renders contacts with MR surfaces, buttons, low- and high-frequency textures. In the first user study, they found that participants perceived Touch&Fold to be more realistic than a previous haptic device. In the second user study, researchers found that the device allowed the participants to use the same finger to manipulate handheld tools, small objects, and even feel textures and liquids with the help of a folding mechanism while feeling haptic feedback when touching MR interfaces.

Overall this device allows the user to interact with the virtual world and quickly tucks away when the user interacts with real-world objects.

Canique Climat: A Unique temperature/humidity sensor or ultra low power systems

Posted on 24 June, 2021 by DM

As a maker, you may have come across various IoT temperature and humidity monitors with low-power consumption. Canique Climat is a unique sensor that features ultra-low power consumption of only 2.5uA when powered by a 1.25V battery. The latest revision offers:

reduced quiescent current from 9.5µA to 2.5µA (@ 1.25V)
reduced ripple voltage during RX to 4.5mV (@ 1.25V)

This low power consumption makes it suitable for remote sensing and other applications where changing the battery is very difficult.

The Canique Climat sensor can be used in the following cases:

Providing temperature/humidity data to the air conditioning system of a building
Monitoring storage conditions of medical products
Monitoring temperature and humidity of your wine cellar
Testing a refrigerator for the correct functioning
Getting notified about left open doors/windows in winter months
As temperature sensors in hotel rooms, holiday homes, or Airbnb apartments
As monitoring system in a greenhouse where plants are automatically watered
In agriculture: e.g., in a barn.
In outdoor applications: for climate studies

Vienna-based Canique has designed this ultra-low-power temperature/humidity sensor that can run off a single AA lithium battery for up to 20 years, up to 10 years with a single AA alkaline battery. The Climat sensor demonstrates the open field range between 400 and 800 meters using the 868MHz band using a max. transmission power of +13dBm. The measurements are plotted in an Android app Canique Cockpit. Also, one can get notified when critical thresholds are reached. The monitored data can be accessed via any web browser or any device like Smartphone, Tablet, or PC.

Source: https://hackaday.io/project/179781/gallery#dd4cdce35bddd5d6f27ff6a1b6c3d2d7

At the core of the sensor is an Arm Cortex-M0+ microcontroller. The low-power consumption is achieved by transmitting data in regular intervals of 30 seconds or 60 seconds. The sensor draws only a minimal amount of current when not transmitting. The transmission cycle may take about 30ms. The sensor uses non-rechargeable lithium batteries as the internal resistance of a typical alkaline battery increases at low temperatures. The software takes advantage of low-power modes exclusively, which transmit data at just two bytes in size by limiting the format and switching from using characters to integers. The software can manage to shrink the message to only 2 bytes.

The Climat sensor encrypts the data a symmetric 256-bit AEAD cipher to ensure that the received data is authentic and has not been decrypted by some other party. Additionally, there are countermeasures implemented against replay attacks.

The sensor is ultra-precise. The humidity is measured with a typical absolute precision of ± 1.8%, while the temperature is measured with a typical absolute precision of ± 0.2°C. Moreover, the battery status is measured with ± 1mV precision every hour. When the battery voltage drops below 0.8V, the device stops working, and you get notified.

The Canique Climat sensor is set to release in the middle or at the end of 2021. Further information can be found here.
