This is a voltage divider module which reduces the input voltage by a factor of 5. It enables monitoring of higher voltages (up to 25V) with a microcontroller that has an analogue input range of 0-5V. The module includes screw terminals for easy and secure connection and is based on the resistive voltage divider design. The minimum voltage that can be detected is 0.02445V and the resolution is 0.00489V. The module can be connected to an expansion board (such as Arduino) through a 3P connector and can also be used with an IICLCD1602 LCD to display the voltage. The divider ratio is 5:1 and the resistor tolerance is 1%.
