Description
Voltage sensor is a precise low cost sensor used for measuring voltage.The Voltage Sensor Module 25V allows use of the analog input of a microcontroller to monitor voltages higher than it is capable of sensing.
For example, with a 0-5V analog input range, a voltage of upto 25V can be measured.
Includes screw terminals for convenient and secure connection of a wire.
It is based on principle of resistive voltage divider design.
Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.
