DIYmall Voltage Sensor for Arduino DC0-25V with Code(pack of 2pcs)<br> Description:<br> This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, 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 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> 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> Output interface:<br> + 5V or 3.3V<br> - GND <br> S Arduino AD pins<br> Package included:<br> 2 X Voltage Sensor<br>
