Manual: DFRobot Instrument Documentation

The DFRobot Tipping Bucket has a few key components when it comes to setting up the instrument.

• Tipping Bucket - Collects water

• Sensor - Acts as the brain of the instrument

• Wires - At the end of the sensor cable, the ribbon splits into four (4) wires.

• Green - SDA (Serial Data Acquisition for I2C Interface) - GPIO Pin 3
• Blue - SCL (Serial Clock Line for I2C Interface) - GPIO Pin 5
• Red - Power (positive) - GPIO Pin 4
• Black - Grounding power (negative) - GPIO Pin 6

By now, you should have your Raspberry Pi computer completely set up, with a DAQ HAT.

1. Connect the Sensor to the tipping bucket with the large port.
2. Connect the wires to the proper GPIO pins
3. To use with the ADPAA Python code, you will then have to download modbus-tk on the Raspberry Pi
   1. sudo pip install modbus-tk –break-system-packages
