Smart Electronics Level 3 Sensor Module with 25V Maximum Voltage Detector for Arduino
Smart Electronics Level 3 Sensor Module with 25V Maximum Voltage Detector for Arduino
This module is based on the principle of resistive voltage divider design, can make the red terminal connect the input voltage
to 5 times smaller. Arduino analog input voltage up to 5 v, module voltage sensing input voltage not more than 5 Vx5 = 25 V V,
input voltage not more than 3.3 Vx5 = 16.5 V). Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489 V (5 V / 1023),
so the minimum input voltage sensing module voltage is 0.00489 Vx5 = 0.02445 V.
Voltage input range: DC0-25 V Voltage sensing range: DC0.02445 V-25 V Analog resolution voltage: 0.00489 V Output interface: “” + “” connected 5 / 3.3V, “” - “” connected GND, “” “” connected Arduino AD pin DC input interface: positive red terminal with VCC, negative with GND connector3P , by connecting this module with the Arduino board expansion, not only is it easier to detect the battery voltage,
but also you can use the IICLCD1602 LCD display to show the voltage.
