Voltage Sensor Module Voltage Detection

DC Voltage Sensor Module



This module is based on principle of resistive voltage divider design DC Voltage Sensor Module, can make the red terminal connector input voltage to 5 times smaller .Arduino analog 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 module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.



DC Voltage Sensor Module

A voltage sensor is a sensor used to calculate and monitor the amount of voltage in an object. Voltage senso can determine the AC voltage or DC voltage level. The input of this sensor is the voltage, whereas the output is the switches, analog voltage signal, a current signal, or an audible signal.

Senso are devices that can sense or identify and react to certain types of electrical or optical signals. The implementation of a voltage sensor and current sensor techniques have become an excellent choice for the conventional current and voltage measurement methods.
