Doppler radar module with 24GHz transceiver. It allows for precise distance measurement and motion detection. The board communicates via the UART interface. Seeed Studio 101990883

Motion detection module featuring Panasonic\'s EKM series PIR sensor. The EKM series is optimised for detecting small movements and is ideal for detecting movement in a small area around the sensor. It offers digital output in 32 zones with a detection distance of 5 m and a detection area of 90° x 90°. SparkFun SEN-21999

Module with PIR sensor HC-SR501. It can detect movement up to 7 meters with a detection angle of 120 degrees

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

Module with the PIR EKMB1107112 motion sensor, the standby power consumption of up to 1 uA. SparkFun SEN-17373

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

Occupancy sensor based on 24 GHz millimeter wave technology with FMCW, enabling precise detection of people, measuring distances up to 25 m and movement speed. Thanks to high resistance to environmental interference, it works reliably in conditions such as dust, light or temperature changes, outperforming traditional PIR and ultrasonic sensors. Compact size and installation flexibility make it perfect for intelligent lighting, security systems and building automation. DFRobot SEN0609

Module with PIR EKMC4607112K motion sensor, power consumption in standby mode up to 170 uA. SparkFun SEN-17372
