Replacement Weather Station Rain Gauge - Tipping Bucket Type 0.3mm Rain / pulse

24.90€
Qty:

his tipping bucket rain gauge has a magnetic reed switch that closes momentarily each time the gauge measures 0.011" (0.2794 mm) of rain.

The 9 foot (3 meter) cable terminates in an RJ11 modular plug, and can easily be extended using a common telephone extension cable.

The gauge can be easily connected to an Arduino, Rapberry Pi, or any microcontroller. Commonly a pull-up resistor (4.7k ohms is typical) will be used to pull the input pin high, and the other side of the gauge's switch will be connected to ground, pulling the pin low each time the switch closes.
