3D Gesture Sensor (Mini) is an inductive gesture sensor detecting such effects as turning clockwise / counterclockwise or the direction of movement. It is powered by 3.3 ... 5V and the range of gesture detection is up to 5cm. DFRobot SEN0202

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

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

Air speed sensor module based on the FS3000-1005 chip. The board is equipped with Qwiic connectors. SparkFun SEN-18377

The modPhotoelectric sensor with an LM393 comparator and a 10 mm slot width enables reliable detection of interrupters in applications requiring pulse counting, position detection, and speed measurement. Thanks to its digital TTL output and mounting holes, it is suitable for direct integration with microprocessor systems. modPhotoelectric

A sensor for measuring the wind speed. It has a built-in Hall sensor and enables measurements in the range from 0 to 32.4 m/s. DFRobot SEN0483

Universal weather station for measuring wind speed and direction, temperature, humidity and atmospheric pressure, compatible with micro:bit, Raspberry Pi, ESP32 and Unihiker controllers. It has 16 MB of internal memory, which allows for 160 days of data storage at a minute sampling rate, and data can be exported via USB Type-C port. The sturdy metal casing with a waterproof protective coating and compatibility with tripods make the station ideal for field atmospheric research and educational projects. DFRobot EDU0157-EN

Module with PIR S16-L221D motion sensor. The board is equipped with a Grove connector and communicates via a digital interface. Seeed Studio 101020353

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

Module with PIR S16-L221D motion sensor. The board is equipped with a Grove connector and communicates via a digital interface. Seeed Studio 101020617

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

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
