Crowtail-PIR Motion Sensor 2.0 is a digital motion sensor for use in alarm systems, building automation and interactive projects. It provides a wide detection angle and adjustable range in a compact form with easy connection through the Crowtail interface.

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

PIR infrared sensor. Reacts to the change of infrared radiation. Range up to 7m.

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

A module with a PIR motion sensor, which has outputs for controlling 230 V LED lighting. ModPirSen

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.

IR optical sensor module based on a slotted optocoupler. It enables the construction of an incremental encoder

Module with PIR motion sensor SR-602. It can detect movement up to 5 meters

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

Digital sensor for measuring accurate and drift-free angular displacement. It is constructed from highly durable medical-grade silicone elastomers. It communicates via an I2C interface. SparkFun SEN-15244
