Water Weel Rain Sensor

A water weel rain sensor with ESP8266 and Micropython.
1. print all 3D parts
2. glue RainSensor-CapTop and RainSensor-CapTop_2, RainSensor-CapBottom and RainSensor-CapBottom_2
3. cut M3 threads into RainSensor-Cylinder and RainSensor-CapTop
4. drill 2mm hole in the RainSensor-WaterWeel
5. the water weel axle is a peace of filament 27mm, bend it straight; add left and right of the weel two washers 2mm hole.
6. paint the rain sensor housing outside with acryl paint

Assemble two disc magnets 6mm x 2mm into the holes of the RainSensor-WaterWeel.
Note the magnet polarity to the hall sensor!
