A voltage divider designed as a simple circuit that turns a large voltage into a smaller one. Voltage Divider Module referred to as examples of potentiometer- variable resistors which to create an adjustable voltage divider. This module functions using two series resistors and an input voltage. Thereby creates an output voltage that is a fraction of the input. This voltage divider module compatible with Arduino and thus interfaced easily.
This Voltage Divider Module provides an interface for measuring external voltage. Thereby eliminating the need to connect resistance to the input interface. Using a dial switch the voltage gain can be selected. The module operates at a supply voltage of 5V DC with an accuracy of <= 0.1%. In this module, the measured voltage reduced down by a fixed ratio so that the ADC of the Arduino can detect the value and calculate the measured voltage. Moreover, this module offers avsampling resistance with precision resistors, 0.5% precision, and 50PPM temperature coefficient to ensure the detection accuracy effectively.
