[BEST] Voltage Sensor Module 25V for Arduino IoT Raspberry Nodemcu Volt Sensor Reader Measure Module Voltage Divider

This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5V, 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), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.

Specification :

- Voltage input range : DC0-25 V
- Voltage detection range : DC0.02445 V-25 V
- Voltage analog resolution : 0.00489 V
