A weather sensor kit containing the three core components of weather measurement: wind speed, wind direction, and rainfall. Ideal for building your own weather station for agricultural, meteorological, or hobbyist applications.

All sensors use sealed magnetic reed switches rather than active electronics, making them simple to interface with any microcontroller. Just supply a voltage and read the switch closures or resistance values. All sensors are terminated with RJ11 connectors.

Key Features

• Wind Speed (Anemometer) – Switch closure once per rotation; 1.492 MPH = 1 closure per second
• Wind Direction (Vane) – Voltage output via resistor combinations; up to 16 positions
• Rainfall (Tipping Bucket) – Momentary switch closure per 0.011" (0.2794 mm) of rain
• Passive Sensors – No active electronics; sealed magnetic reed switches for reliability
• RJ11 Connectors – All sensors terminated with RJ11 cables

Specifications
