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

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

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.
