DC Voltage Sensor 0V to 25V

DC Voltage Sensor works with Arduino analog input voltages up to 5 v, the voltage detection module input voltage should not exceed 5Vx5=25V (if using 3.3V systems, input voltage should not exceed 3.3Vx5=16.5V). Most 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.

CONNECTING

• Pin Vcc in the Sensor –> +5V in Arduino
• Pin GND in the Sensor –> GND in the Arduino
• Pin S in the Sensor –> Analog pin in Arduino such as A1
