You can learn how to get the schematic diagram through this document: https://heltec-automation-docs

but even if you do not have much experience

We also provide a USB-A output interface that you can use to connect to other devices using a USB cable

It is small in size

Rain / Raindrop Detection Sensor Kit with Relay Module 2S Data Acquisition port:NOThe 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
