Energy-saving 24 GHz sensor LD2410S based on FMCW technology and the Doppler effect, designed to detect human presence and micro-movements in real time. Thanks to the built-in AI algorithm and a range of up to 8 meters and a wide detection angle (±60°), it is perfect for building automation, smart lighting and IoT devices. It supports UART and GPIO interfaces, offers very low power consumption (from 0.04 mA in standby mode) and allows configuration through intuitive tools, making it ideal for integration in modern projects.

The Gravity Occupancy Sensor uses 24 GHz FMCW radar technology, enabling precise presence detection at a distance of up to 8 meters and movement and distance measurement up to 12 meters. Thanks to its high resistance to environmental interference, it works reliably regardless of light, temperature or dust, effectively detecting both static and dynamic objects. Compatibility with Arduino, ESP32, Raspberry Pi and a simple Gravity interface make it an ideal solution for intelligent lighting, building automation and security systems. DFRobot SEN0610

PIR motion sensor module for Arduino and Raspberry Pi. DFRobot SEN0018

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
