Voltage Sensor For Arduino Dc Raspberry Pi Amplifier Digital Current Dc0-25V

DESCRIPTION:

• Voltage input range: DC0-25V
• Voltage detection range: DC0.02445V-25V
• Voltage Analog Resolution: 0.00489V
• DC input connector: Terminal cathode connected to VCC, GND negative pole
• Output interface: "+" then 5/3.3V, "-" then GND, "s" then the for Arduino AD pins
