This Voltage Detection Sensor Module 25V, which utilizes a resistive voltage divider, is a simple yet highly effective tool that enables you to monitor voltages much higher than the analog input range of a microcontroller, by reducing the input voltage by a factor of 5, allowing for accurate voltage measurements up to 25V when using a 0-5V analog input range, or 16.5V in systems operating at 3.3V, and it provides a convenient screw terminal for secure wire connections, while simulating a resolution of 0.00489V per bit on Arduino AVR chips with a 10-bit ADC, thus enabling detection of input voltages as low as 0.02445V.
Features:
The module can also be used in conjunction with an IICLCD1602 LCD to conveniently display the detected voltage. With the 3P connector, you can easily connect this module to the expansion board of an Arduino, making it much simpler to monitor the battery voltage.
Package Includes:
1 × Voltage Detection Sensor Module.
