Sensors

Sensor breakout boards for Arduino, Raspberry Pi, ESP32 and other microcontrollers. They cover biosignals, temperature, motion, current and voltage, and environmental sensing.
For signals from the body, see Biomedical Sensors. For solder-free I2C wiring, see Qwiic. Boards designed by Protocentral are open hardware, with schematics and libraries on GitHub.
