20pcs Voltage Sensor Modules for Arduino Robot Standard Electronic

Description: 1. Product Details 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 2. Parameters 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 3. Reference Code #include int val11; int val2; void setup() { pinMode(LED1,OUTPUT); Serial.begin(9600); Serial.println("Emartee.Com"); Serial.println("Voltage: "); Serial.print("V"); } void loop() { float temp; val11=analogRead(1); temp=val11/4.092; val11=(int)temp;// val2=((val11%100)/10); Serial.println(val2); delay(1000); }
