MH Sensor Series
This is an easy to use sensor module you can use to sense varying voltage, but only for positive voltage. This module can help you to turn down a range of input voltage from 0 – 25V to 0 – 5V via a resistive voltage divider network. It comes with a screw terminal to connect the module to your load circuit so you can connect it easily without the need of soldering (depend on your load circuit).
Note : this sensor only works in analog mode. You can connect the analog output (AO) pin to Arduino to read voltage directly from the module. If you use this module on 3.3V devices such as ESP8266, you can only measure up to 16.5V maximum, more than this voltage will probably damage your device. NEVER use this to measure negative voltage or positive voltage of more than 25V!
