DFRobot Gravity - voltage divider 1/5

A voltage divider is used, when the measured voltage has a larger value than the range of A/D converter. The device works in the range from 0,0245 V to 25 V. The output voltage is proportional to the input voltage, in a ratio of 5 to 1.

Connection diagram of the voltage divider

• Supply voltage: from 3.3 V to 5 V

The product is compatible with Arduino

Online, you can find the user manual, along with examples for the Arduino.

The sensor communicates with the microcontroller in analog way. It has 3-pin connector pitch and 2-pin screw connector for connection of the measured voltage. Pins from controller's side are as follows:
