Hello,

Let me introduce my new heated rain tipping bucket:

I bought it in China from the company Hunan Rika Electronic Technology on Alibaba.
The device RK400-01 looks very precise even though it belongs to their "low cost" equipment.
They also offer it in a variant with a heater, but I decided to make DIY-heating due to the price.

Basic parameters:
highly polished stainless steel construction
diameter 200 mm, height 350 mm
measured rainfall intensity - max 4 mm/min
allow rainfall intensity - max 8 mm/min
resolution 0.2 mm
accuracy +-4 % (2 mm/min)
output - reed switch pulses
weight 3.5 kg

After unpacking:


The heating element I made from pieces of heating cable with a specific resistance of 33 Ohm/m,
I used 3 x 60 cm:


For 12 V supply, the resulting heating output is approximately 20W.


For control I used a purchased module with its own temperature sensor:


The total cost was almost $ 500. But I hope that this investment will pay off in the accuracy
and stability of measurement and the ability to measure rainfall even in the winter.
