ITEM NAME:5x Standard Vol Sensor Module Test Electronic Bricks For Robot Description: This module is based on  resistive voltage divider design principles, It is capable of reducing the voltage of the input terminal connection five times. You can use a 5V maximum voltage on the ADC side of the module so which allows for a maximum of 25V on the input side. If 3.3V is used, the input voltage must not exceed 16.5V. Because  AVR chips use 10 bit ADC, the maximum resolution of this module is 0.00489V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489V × 5 = 0.02445V. Parameters: Input voltage range: DC0-25V Voltage detection range: DC0.02445V - 25V Voltage analog resolutions: 0.00489V DC Input: positive terminal connected to VCC, GND negative pole Output interface: "+" then 5 / 3.3V, "-" then GND, "s" then the AD pin Size:  Approx 27*14*12mm/ 1.06 x 0.55 x 0.47inch Reference Code: #include int val11; int val2; void setup () void loop () { float temp; val11 = analogRead (1); temp = val11 / 4.092; val11 = (int) temp; // val2 = ((val11% 100) / 10); Serial.println (val2); delay (1000);.Float temp;. Output interface: "+" then 5 / 3.3V, "-" then GND, "s" then the AD pin. temp = val11 / 4.092;. val11 = analogRead (1);. Reference Code void loop (). Serial.print ("V");.
