DFRobot’s New 24GHz mmWave Radar Sensor module

Posted on by DM

Human presence detection is essential for safety, security, or other reasons. There are various software and hardware technologies and methods for detecting the presence of a human body in an area of interest (AOI). Among those techniques, Radar technology is one of the widely used techniques if the aim is to detect only the presence of a human. As we all know, radar is a system that uses radio waves for the detection of an object and to determine its distance, velocity, and angle. A radar system consists of a transmitter that transmits electromagnetic waves (generally microwave). The waves transmitted reflect off the object and return to the receiver, giving information about the object’s location and speed. The radar technology can also detect the unique signature of a human’s breathing pattern and heartbeat.

The mmWave (millimeter-wave) Radar sensors are very accurate. It is a contactless technology that operates in the spectrum between 30GHz and 300GHz. Due to the small wavelengths, it can provide sub-mm range accuracy and can penetrate certain materials such as plastic, drywall, clothing. Further, it is not affected by environmental conditions such as rain, fog, dust, and snow. Due to short wavelengths, this radar sensor provides high resolution, and the antenna required is relatively small.

DFRobot’s new 24GHz millimeter-wave radar sensor can sense human presence within the detection area. Moreover, it can even detect static or stationary humans, such as a sleeping person.

The DFRobot radar sensor’s wiki page shares information about the working of this sensor. Firstly, the sensor transmits FMCW(Frequency Modulated Continuous Wave) and CW radio waves to the sensing area. Secondly, the waves get reflected by all targets which are in moving, micro-moving, or weak moving state in the area. The waves are converted into electrical signals by the MMIC circuit in the sensor. These signals are then processed with the help of data algorithms.

DFRobot states that:

“The millimeter-wave radar can sense the human presence, stationary and moving people within the detection area. Moreover, it can even detect static or stationary human presence, such as a sleeping person. There are two ways provided to output detection result: serial port and I/O port switch quantity. Besides that, the sensor module features strong sensing reliability, high sensitivity, small size, easy to be used or embedded in applications.”

The 24GHz radar module is designed for microcontrollers. It draws 90mA of current and can run at 3.6-5V supply. Talking about its range, it can detect up to 9 meters and has a wide beam angle.

Features of the human detection radar module are:

  • Human presence sensing: sense if there is a human body in the area
  • I/O port switch quantity input and output control
  • Serail port input and output control
  • Strong anti-interference ability. Not to be affected by snow, haze, temperature, humidity, dust, light, noise, etc.

The sensor module is available for sale on DFRobot’s website!

An Inkscape extension for exporting drawings into a KiCad PCB

Posted on by DM

Certain electronic applications may require circuits that can fit in a small space, may call for the layout such that the outputs and input pins line up in the enclosure. This can all be possible with custom Printed Circuit Boards(PCBs). Custom PCBs can be used in industries, medical equipment, games, and various other applications. Makers also create fancy custom PCBs for keychains, making gamepads, making decorative pieces, etc. Industries use custom PCBs for verification. They add various indicators in the PCB design to validate the prototype.

When you design a custom PCB, you have complete control over your design. In other words, you have control over the placement of every component and every piece of copper on the PCB. This control not only allows you to create circuits of various shapes and sizes but also to create circuits with minimal parasitics. Moreover, for some designers, appearance matters, and custom PCBs look more professional.

But designing a custom PCB is not an easy task. First, an individual has to create an outline of the PCB in Adobe Illustrator or similar software. Then, import it into PCB designing software and create bare copper areas. Finally, one arranges the components and creates the final design. Budi Prakosa, Frontend Engineer at Codeme.co.id made an Inkspace extension for exporting drawings into a KiCad PCB. To use the extension, you need to add the extensions file in InkScape ‘s User Extensions and then draw the PCB.

For using this feature with Eagle, you need to use this svg to Eagle CAD converter

Following are the features of this Inkspace extension:

  • Draw Any kind of shapes without restriction
  • Supports Drill Pad, and custom drill size
  • Supports Edge Cut (PCB Shape)
  • Works on OSX, Windows, and Linux

Budi Prakosa documented his extension Svg2Shenzen where he included the extension files, instructions on how to use the extension, and few examples as a tutorial.

2 years after his announcement about his extension, Budi posted on the openhardware forum:

“I’m happy that svg2shenzhen now widely used to create PCB art, badges, antennas, and was contacted by a student in Stanford that they use it to design ultra-small vibrating component”

Researchers at the Duke University Developed the World’s First Fully Recyclable Printed Electronics

Posted on by DM

With the increase in demand for wearable electronic devices, the need for flexible, thin, and compact electronic circuits also arises. Wearable devices and many other sophisticated systems need sensors that can be attached to various kinds of surfaces or substrates. Therefore, it is necessary for the sensors to be flexible and also hold the same electrical property. In addition, there is a constantly growing demand for flexible indicators and displays. The most crucial component of an electronic system is, however, the transistor. There is a lot of research and development ongoing for Thin-Film Transistors (TFTs). These special types of transistors are made by depositing thin films of the semiconductor layer as well as the dielectric layer and metallic contacts on a non-conducting substrate.

Printed Electronics: A Summary

Very thin electronic devices and circuits are part of the printed electronics terminology. Printed Electronics is a new way to manufacture electronic components and circuits. It refers to the process in which printing technology is utilized to produce various electronic circuits, displays, sensors, RFID systems, solar cells, etc. We’re all aware of conductive ink which is an ink that can result in a printed object which conducts electricity. It is created mainly by infusing graphite. Similarly, some well-known technologies for printing electronics are gravure, flexographic, offset, and inkjet printing. Flexographic printing can print the thinnest layers while gravure is the fastest technique for printing electronic circuits.

The printing is based on organic conducting, semiconducting as well as printable organic materials. The printed transistors are fabricated on thin plastic film substrates with various printing processes. Thin-film transistors can also be based on organic semiconductors. The benefit of organic printing is its eco-friendliness.

An Overview of a Research at the Duke University on Fully Recyclable Printed Electronics

The market for printed electronics is constantly growing. The market was predicted to increase to 45 billion USD in 2021. With this, some questions arise like what happens when the printed electronics become waste? Can they be recycled? The silicon-based systems cannot be recycled easily and they just add up to landfills. Similarly, in printed electronics, the use of nanomaterials is a crucial part.

Engineers at the Duke University have successfully developed the world’s first fully recyclable printed electronics. They demonstrated the creation of transistors with three-carbon-based inks. These transistors can be easily printed onto paper or other flexible materials. Carbon nanotubes and graphene inks are used for semiconductors and conductors respectively. The recyclability is due to the use of nanocellulose ink which is derived from wood.

“Nanocellulose is biodegradable and has been used in applications like the packaging for years,” said Aaron Franklin, the Addy Professor of Electrical and Computer Engineering at the Duke University. He further added, “And while people have long known about its potential applications as an insulator in electronics, nobody has figured out how to use it in a printable ink before. That’s one of the keys to making these fully recyclable devices functional.”

The researchers developed ways for suspending crystals of the extracted nanocellulose which will act as an insulator in printed transistors. The team showed that their recyclable printed transistor is well enough for use in a variety of applications, even six months after the initial printing. Further, the recycling process recovers 100% of the materials and the materials lose very little of their properties.

“Recyclable electronics like this aren’t going to go out and replace an entire half-trillion-dollar industry by any means, and we’re certainly nowhere near printing recyclable computer processors,” said Franklin. “But demonstrating these types of new materials and their functionality is hopefully a stepping stone in the right direction for a new type of electronics lifecycle.”

Programmable Frequency – Continuous Conduction Mode (CCM) – Boost Power – Factor Correction (PFC) Controller

 

The circuit described here is a simple PFC controller using the UCC28180 chip from Texas instruments. The controller operates under average current mode control at a fixed programmable switching frequency of 116 kHz. Simple external current and voltage loop compensation, along with advanced protection features, make this controller ideal for server and desktop power supplies, industrial power supplies, and white goods. The module is a flexible and easy-to-use, active Power-Factor Correction (PFC) controller that operates under Continuous Conduction Mode (CCM) to achieve high Power Factor, low current distortion, and excellent voltage regulation of boost pre-regulators in AC – DC front-ends. The controller is suitable for universal AC input systems operating in 100-W to few-kW range with the switching frequency programmable between 18 kHz to 250 kHz, to conveniently support both power MOSFET and IGBT switches. An integrated 1.5-A and 2-A (SRC-SNK) peak gate drive output, clamped internally at 15.2 V (typical), enables fast turn-on, turn-off, and easy management of the external power switch without the need for buffer circuits. Low-distortion wave shaping of the input current using average current mode control is achieved without input line sensing, reducing the external component count.

In addition, the controller features reduced current sense thresholds to facilitate the use of small-value shunt resistors for reduced power dissipation, especially important in high-power systems. To enable low current distortion, the controller also features trimmed internal current loop regulation circuits for eliminating associated inaccuracies. The module requires few external components to create a complete PFC Controller. In the future, we will publish few PFC drivers using this module. Refer to the datasheet of UCC28128 to configure the board as per requirement.
