Would it be possible to add the DFRobot SEN0545 rain detection module ?

Describe the problem you have/What new integration you would like

Actually, the only supported rain detection modules are from Hydreon RG-15 or RG-9. They are quite expensive (99USD and 49USD) DFRobot are selling an Intelligent Rain Detection Module for about 21USD, less than the half.

I couldn't find many reviews about the quality of this product, and how it compares with Hydreon solutions. By the way, having a more affordable device for our project would be appreciated, and add more diversity.

This device specifications :

• Communication : UART (115200bps)
• Voltage / Operating Current : 3.3V / <50mA (perfect for direct powering with the ESP32)
• Sensors : Rain detection / Ambiant light detection / Temperature detection

Please describe your use case for this integration and alternatives you've tried:

My use case, would mainly be rain detection for pergola automation, but light and temperature is interesting as well.
