<b>Description:<br></b> This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because for Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.<br><br> <b>Specification:<br></b> Voltage input range: DC0-25V<br> Voltage detection range: DC0.02445V-25V<br> Voltage Analog Resolution: 0.00489V<br> DC input connector: Terminal cathode connected to VCC, GND negative pole<br><br> <b>Output interface:<br></b> + 5V or 3.3V<br> - GND <br> S for Arduino AD pins<br><br> <b>Package included:<br></b> 10 X Voltage Sensor
