Kit represents the three core components of weather measurement: wind speed, wind direction and rainfall.
It uses sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements.
All of the sensors in the weather meter kit are passive components. This means you will need a voltage source in order to measure anything with them.
Sensors include Wind vane, Cup anemometer, Tipping bucket rain gauge. RJ11 terminated cables.
Stand: Two-part mounting mast, Rain gauge mounting arm, Wind meter mounting bar, 2x Mounting clamps and 4x Zip ties.
