Wind direction sensor with a measuring range up to 60 m/s and 360° ensures high accuracy and fast response time, thanks to the use of low-resistance bearings and precision components. It supports various output signal types, including analog (0–5 V, 4–20 mA) and digital (RS485, LoRa, GPRS, 4G), enabling broad integration in meteorological, agricultural, and industrial systems. The durable polycarbonate construction and IP65 protection rating ensure reliable operation even in harsh environmental conditions.

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

Module with a human presence and movement sensor designed based on the STHS34PF80 infrared sensor. Enables monitoring of radiation and ambient temperature within an 80° field of view. The sensor can precisely detect movement and presence within a range of 4 m. It uses the I2C or SPI interface for communication and has built-in Qwiic connectors. SparkFun SEN-23253

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

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

HLK-LD2450 is a 24 GHz radar module designed for precise human presence and motion detection in intelligent IoT systems. modHLK-LD2405

The GR10-30 sensor module, which can recognise up to 12 user gestures from a distance of up to 30 cm. It supports communication via both UART and I2C interfaces. DFRobot SEN0543

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
