Aktronics Voltage Detection Sensor Module For Arduino, ARM and other MCU PACK OF 2 Electronic Components Electronic Hobby Kit

A simple but very useful module which uses a potential divider to reduce any input voltage by a factor of 5. This allows you to use the analogue input of a microcontroller to monitor voltages much higher than it capable of sensing. For example with a 0-5V analogue 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 principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Microcontroller 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). Controller which chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V. Specifications: Material: Electric Parts Main Color: Blue Max Voltage Range: 25V Size: 2.7*1.3cm/1*0.5in Weight: 3g(approx.)
