Description: This DC voltage sensor can detect voltage from 0 to 25V. Sensor is based on resistance points pressure principle, and it can make the input voltage of red terminal reduce 5 times of original voltage. The max Arduino analog input voltage is 5 V, so the input voltage of this module should be not more than 5 V x 5 = 25 V ( if for 3.3 V system, the input voltage should be not more than 3.3 V x 5 = 16.5 V ). Because the Arduino AVR chip have 10 bit AD, so this module simulation resolution is 0.00489 V (5 V / 1023), and the input voltage of this module should be more than 0.00489 V x 5 = 0.02445 V. Sketch: int analogInput = A1; float vout = 0.0; float vin = 0.0; int value = 0; float R1 = 30000.0; float R2 = 7500.0; void setup(){ pinMode(analogInput, INPUT); Serial.begin(9600); Serial.print("DC VOLTMETER"); } void loop(){ // read the value at analog input value = analogRead(analogInput); vout = (value * 5.0) / 1023.0; // see text vin = vout / (R2/(R1+R2)); Serial.print("INPUT V= "); Serial.println(vin,2); delay(500); } Photo:
