Product details

Voltage Detection Sensor Module 25V- great for Arduino

This is a simple but very useful module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.

For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.

This module is based on the principle of resistive voltage divider design, 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).

 Parameters:
  • Input voltage range: DC0-25V
  • Voltage detection range: DC0.02445V-25V
  • Voltage analog resolutions: 0.00489V
  • DC Input (to measurement): positive terminal connect to VCC, negative terminal to GND
  • Output interface (to Arduino / AVR board): “+” to 5 / 3.3V, “-” to GND, “s” to Arduino Analog input pin
