The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

The amount of light reaching the LDR from the LED decreases as the pipe is bent, and with a simple divider circuit a voltage can be read by an Arduino.

Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs.
