Open Source Unsurv Offline Features ESP32, GNSS

A campaign has been launched on Crowd supply for Unsurv, which is an offline privacy-friendly, small, lightweight PCB (43 mm x 32 mm) loaded with an ESP32, GNSS reciever and NFC capabilities. It functions by using a combination of OpenStreetMap data on the SD card, and a custom Android app, enabling you to gather GNSS data throughout the day, and easily analyzing it and using it later on. Speaking about Unsurv, the company says:

“Our goal is to enable a broad discussion about invasive technologies that follow us increasingly closer in our daily lives and to help disrupt familiarization to offline surveillance.”

You can use Unsurv for a variety of other location-tracking functions, and you can access your Unsurv data easily via your smartphone and the dynamic NFC Tag which is fitted into the case. The Unsurv features a tiny BMA400 accelerometer which helps save precious battery capacity by managing power-saving features. It can even be adapted as an input device with tap and double-tap recognition. It is easy to use, just add a single cell LiPo battery, or USB power bank for more demanding tasks, and start gathering data. Unsurv is very efficient because, at the end of the day, most common Global Navigation Satellite System (GNSS) projects appear onto Unsurv offline, inclusive of surveillance cameras you would otherwise not notice.

Unsurv has many uses. It can perform simple location logging, automated commute tracking, and map WiFi signal strength. This enables you to log your daily commute by bike and ensure that no one except you has the data. You can also map WiFi signal strength in your city and create a map of free WiFi access points. Also, if you use vehicles commercially and want to claim tax benefits, you can use Unsurv offline to log each trip. Unsurv offline is open source, so it enables you to come up with your own custom uses.

When you use an always-on location service on a smartphone, it increases power consumption and is not sustainable to use throughout the day. It can also expose your location to third parties, thereby taking away from the security focus. However, Unsurv solves all of this problems since it is a custom lightweight, portable, low-power board with every feature you need for powerful location tracking.

Maxim Integrated MAX31827 Low-Power Temperature Switch

Maxim Integrated MAX31827 Low-Power Temperature Switch provides an ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SMBus interface. The MAX31827 switch offers high accuracy in a small 6-bump wafer-level package (WLP), making it ideal for a wide range of applications.

The Maxim MAX31827 Low-Power Temperature Switch can be used as a temperature switch with preconfigured thresholds or a temperature sensor with an I2C interface. When the MAX31827 operates as an independent temperature switch, the I2C interface doesn’t have to be used. Without utilizing the I2C interface, the switch can be used in systems that require thermal protection implemented in hardware, without the need for reconfiguration or use of software/firmware during normal operation. Additionally, the one-time programmable (OTP) ALARM functionality enables the use of the MAX31827 as a safety mechanism in systems where power dissipation is challenging.

The I2C/SMBus-compatible serial interface permits standard, write and read commands to read the temperature data and configure the behavior of the sensor. The bus timeout resets the interface if the clock is low for more than 30ms (nominal), and packet error checking (PEC) helps prevent communication errors when used with a master that supports this feature.

The MAX31827 is housed in a 6-bump WLP and operates over a -45°C to +145°C temperature range.

Features

  • Stand-alone temperature switch with preconfigured
  • Alarm thresholds and hysteresis
  • Active high/active low/open drain ALARM output
  • Excellent temperature accuracy
    • Maximum ±1.75°C from -45°C to +145°C
    • Maximum ±1°C from -40°C to +125°C (12 bits)
  • External resistor selects an address for location identification
  • Temperature resolution is selectable from 8 to 12 Bits
  • Selectable timeout prevents bus lockup (default enabled)
  • I2C and SMBus support
  • User-defined alarm settings
  • Selectable PEC for reliable communications
  • Up to 1MHz Bus Speed
  • +1.6V to +3.6V Power supply voltage
