The Rain/Raindrops Detection sensor module can be used for both detecting rain and for measuring the intensity of rainfall.
It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analogue pin. A completely dry board, for example, will cause the module to output 5V.

A good and high quality Smart DMM.. A small suggestion is there could have been a protective cover like a screen guard.. Cheaper Smart DMM s too have such a protective covering.. I noticed some minor scratches on the display, But it's not a deal breaker.. Good value for Money DMM
