Voltage Detection Sensor Module 25V

Voltage Detection Sensor Module 25V

This module is a simple yet highly useful device that utilizes a potential divider to reduce an input voltage by a factor of 5. The Voltage Sensor Module 25V allows you to use a microcontroller’s analog input to monitor voltages much higher than its inherent sensing capability.

For instance, with a 0-5V analog input range, you can measure voltages up to 25V. The module also features convenient screw terminals for secure and easy wire connections.

Based on a resistive voltage divider design, this module reduces the input voltage at the red terminal connector to one-fifth of its original value. For Arduino systems with a 5V analog input, the maximum input voltage should not exceed 5V x 5 = 25V. If you’re using a 3.3V system, the maximum input voltage should not exceed 3.3V x 5 = 16.5V.

The Arduino AVR chips have a 10-bit ADC, providing a resolution of approximately 0.00489V (5V/1023). Therefore, the minimum detectable input voltage for this module is 0.00489V x 5 = 0.02445V.

Note:

Keep in mind, you are restricted to voltages that are less than 25 volts.   More than that and you will exceed the voltage limit of your Arduino input.

Features

Output Interface: “+ ” connected 5/3.3V, “-” connected GND, “s” connected Arduino AD pins

DC input interface: red terminal positive with VCC, negative with GND

You can also use the IICLCD1602 LCD to display voltage.

By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery.
