Gravity: Digital PIR (Motion) Sensor - PIR motion sensor

The module is based on the Acconeer XM125 radar, which uses 60 GHz radar technology, offering distance measurement up to 20 meters and recognition of objects and their movement speed. The sensor is characterized by low power consumption, making it ideal for battery-powered devices, and also allows for various detection modes, such as level measurement or human presence. Supported by the Arduino library and the Acconeer Exploration Tool, the module provides support for monitoring, debugging and configuration, offering a wide range of applications from smart homes to advanced robotics and security systems.

A digital shock sensor that detects hand shake. The spring-type vibration switch allows you to output pulses when the user shakes once in a certain direction. DFRobot SEN0289

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
