Magideal RC_52000708 Wireless Sensor Security System

Description

Description:This module is based on principle of resistive voltage divider designMake the red terminal connector input voltage to 5 times smaller.Arduino 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).Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),The minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.Voltage input range : DC0-25 VVoltage detection range : DC0.02445 V-25 VVoltage analog resolution : 0.00489 VOutput Interface : + connected 5/3.3V, – connected GND, s connected Arduino AD pinsDC input interface : red terminal positive with VCC, negative with GNDBy 3P connector, connect this module with the expansion of board Arduino,Makes it easier for you to detect voltage batteryMaterial: PlasticSize: 2.6*1.4cmPackage include:1x Standard Voltage Sensor Module
