The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.
IoT Weight Logging Scale
This tutorial will show you how to make a scale that logs your weight to a custom website on the Internet. The principles can be extrapolated to any type of data.
Using the A111 Pulsed Radar Sensor with a Raspberry Pi
Learn how to download, build, and use the Acconeer A111 SDK with a Raspberry Pi! The tiny A111 pulsed coherent radar (PCR) adds high-precision, cutting-edge distance measurement for speed-, material-, motion-,or gesture-sensing projects! We’re not talking about simple ultrasonic, or even infrared, sensors here, but 60GHz radar!
Humidity-sensing LED Flower
How about that humidity? This tutorial shows how to add sensing capability to the 21st Century Fashion Kit's RGB flower project.
LSM9DS1 Breakout Hookup Guide
A hookup guide for the LSM9DS1, which features a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer. It's an IMU-in-a-chip!
Single Supply Logic Level Converter Hookup Guide
The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.
Qwiic GRID-Eye Infrared Array (AMG88xx) Hookup Guide
The Panasonic GRID-Eye (AMG88xx) 8x8 thermopile array serves as a functional low-resolution infrared camera. This means you have a square array of 64 pixels each capable of independent temperature detection. It’s like having thermal camera (or Predator’s vision), just in really low resolution.
