Specification Brand : Ruiwaer BulletPoint1 : The product is designed based on the principle of resistance voltage sharing, which can reduce the input voltage of the terminal interface by 5 times. The maximum analog input voltage of Arduno is 5V, so the input voltage of the voltage detection module cannot exceed 5V ¡Á 5=25V (If a 3.3V system is used, the input voltage cannot be greater than 3.3Vx5=16.5V). BulletPoint2 : Product voltage input range: DC0-25V, voltage detection range: DC0.02445 V-25 V, voltage simulation resolution: 0.00489 V. BulletPoint3 : Product DC input interface: positive terminal connected to VCC, negative terminal connected to GND. BulletPoint4 : Product output interface: ''+'' connected to 5/3.3V, ''-'' connected to GND, ''s'' connected to AD pin of Arduino. BulletPoint5 : The product packaging includes: 10pcs DC 0-25V voltage detection modules sensors.
