Voltage Detection Sensor Module 25v for Arduino

Voltage Detection Sensor Module 25v ( 0 to 25v ) for Arduino is a simple module that can be used with Arduino (or any other microcontroller with an input tolerance of 5V) to measure external voltages that are greater than its maximum acceptable value i.e. 5V in case of Arduino. Voltage Detection Sensor Module 25V is based on the principle of resistive voltage divider design, it can make the red terminal connector input voltage 5 times smaller. Arduino analog input voltages up to 5 v. The voltage detection module input voltage is not greater than 5Vx5=25V (if using 3.3V systems, the input voltage is not greater than 3.3Vx5=16.5V). DC 0 to 25v sensor is a simple and very useful module that uses a potential divider to reduce any input voltage by a factor of 5. This allows us to use the Analog input pin of a microcontroller to monitor voltages higher than it is capable of sensing. For example, with a 0V – 5V Analog input range, you are able to measure a voltage up to 25V. This module also includes convenient screw terminals for easy and secure connections of a wire.

Voltage Detection Sensor Module 25v allows you to use the analog input of a microcontroller to monitor voltages much higher than it is capable of sensing. Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of the input voltage detection module is 0.00489Vx5=0.02445V. It is fundamentally a 5:1 voltage divider using a 30K and a 7.5K Ohm resistor. Keep in mind, that 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.
