Description:
This is a simple but very useful Voltage Sensor Module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Sensor Module allows you to use the analogue input of a microcontroller to monitor voltages much higher than it is capable of sensing. For example with a 0-5V analog input range, you can measure a voltage up to 25V. This Voltage Sensor Module also includes convenient screw terminals for easy and secure connection of a wire.
This Voltage Sensor Module is based on the principle of resistive voltage divider design, which can make the red terminal connector input voltage 5 times smaller. Arduino analogue input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).
Arduino AVR chips have 10-bit AD, so this Voltage Sensor Module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of the input voltage detection module is 0.00489Vx5=0.02445V.
