Package Included

- 1 x Voltage Sensor Module

Description: 

- Voltage input range : DC0-25 V
- Voltage detection range : DC0.02445 V-25 V
- Voltage analog resolution : 0.00489 V
- Output interface : "+ " connected 5/3.3V, "-" connected GND, "s" connected AD pins
- DC input interface : positive with VCC, negative with GND

- This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.
- This module 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).
- This module 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
