Voltage Sensor Module-25V-EE542

A simple but very useful module which uses a potential divider to reduce any input voltage by a factor of 5. This allows you to use the analogue input of a microcontroller to monitor voltages much higher than it capable of sensing. For example with a 0-5V analogue input range you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.

Specifications

• Voltage input range : DC 0-25 V

Inputs

• GND – This is where you connect the low side of the voltage you are measuring.   Caution! : This is the same electrical point as your Board ground.
• VCC:  The is where you connect the high side of the voltage you are measuring

Outputs

• S:  This connects to your controller board analog input.
• –:  This connects to your controller board ground.
• +:  This is not connected.  It does absolutely nothing.
