This module allows the measurement of moisture through analog output pins and it provides a digital output when a threshold of moisture is exceeded. The module is based on the LM393 op amp.
It includes the electronics module and a printed circuit board that “collects” the rain drops. As rain drops are collected on the circuit board, they create paths of parallel resistance that are measured via the op amp.

USB to TTL CP2102 Module
This tiny breakout board is used for serial connections over USB (eg. Arduino programming). It’s pinout matches that of the FTDI cable for official and cloned 5V Arduino boards. The chip set used it similar to the popular FTDI – the Prolific CP2102.
The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.
