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 Interfacing) - GPIO Pin 3
• Blue - SCL (Serial Clock Line for I2C Interfacing) - 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 tipping bucket to the large port on the sensor
2. Connect the four colorful wires to the proper GPIO Pins (See above)
3. On a Raspberry Pi, to make the code given by the ADPAA work, you will have to enter the following command into your terminal
   1. sudo pip3 install modbus_tk smbus - -break-system-packages
