Waveshare Photo Interrupter Sensor is an IR optical sensor module with Schmitt trigger and a signaling diode allowing the construction of an incremental encoder. Waveshare Photo Interrupter Sensor

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. SEN-13285

A set with a Doppler radar module and an XIAO ESP32C3 board designed for precise detection of human presence. It allows you to connect additional Grove sensors (analog or with an I2C interface) and expand the functionality. Seeed Studio 110061541
