Module with an incremental encoder with a rotation range of 360°. The board is equipped with a Grove connector and communicates via a digital interface. Seeed Studio 111020001

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

Gravity: 360 Degree Hall Angle Sensor is a rotation angle sensor measuring a value in the range of 0-360 ° with an analogue output, powered by 5V. DFRobot SEN0221

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
