Be careful, the electronic boards needs to be connect on the right side (GND Pin on GND Pin for example).

1. Connect the MKR MEM Shield on the MKR Connector Carrier.

   

2. Connect the MKR WIFI 1010 on the MKR MEM Shield.

   

3. Insert the µSD card inside the MKR MEM SHIELD.

   

The wire need to be connect in the right side.

4. Take the RS485 communication board and connect its wire on.

   

5. Connect the other side of the wire from the RS485 communication board to the SERIAL port of the MKR CONNECTOR CARRIER.

   

6. Take the RTC module and plug its wire on.

   

7. Take the CR1220 lithium battery and insert it on the RTC module.

   

8. Connect the other side of the wire from the RTC module to the TWI port of the MKR CONNECTOR CARRIER.

   

9. Take the voltage divider board and plug its wire on.

   

10. Connect the other side of the wire from the voltage divider board to the A5-A6 of the MKR CONNECTOR CARRIER.

    

Step 2 : Mechanical assembly

1. Take a piece of wood, PVC, or some other non-conductive element, and cut it following the folder “Flowmeter_datalogger_hole.pdf” to do the fixing plate of the different datalogger board. Drill hole to put on the spacer inside it, then fix it.

   

2. Drill a 20 mm diameter hole inside the box 201x163x98mm following the folder “Flowmeter_datalogger_hole.pdf”.

   

3. Insert the SEN0358 sensor inside the box hole, and fix it with one nuts on both side of the box (the nuts are provided with the sensor).

   

4. Fix the Arduino MKR Carrier on the spacer provided for that purpose, with some screw (following the folder “Flowmeter_datalogger_hole.pdf”).

   

5. Fix the RTC module on the spacer provided for that purpose with some screw (following the folder “Flowmeter_datalogger_hole.pdf”).

   

6. Fix the Grove screw terminal on the spacer provided for that purpose with some screw (following the folder “Flowmeter_datalogger_hole.pdf”). This module must be put on top of the RTC module.

   

7. Fix the PVC plate on the bottom of the box, with screw, by routing the sensor wire through the PVC plate hole.

   

8. Take an independant red wire, and the brown wire from the SEN0358 sensor, and connect them both inside the VOL port of the voltage divider board. Screw them.

   

9. Take a independant black wire, and the black wire from the SEN0358 sensor, and connect them both inside the GND port fo the voltage divider board. Screw them.

   

10. Take the RS485 communication board and connect the SEN0358 sensor wire inside using a flat screwdriver : the blue wire must be connect on the B port and the wire must be connect on the A port.

    

11. Fix the RS485 communication board on the spacer provided with screw.

    

12. Fix the voltage divider board on the spacer provided for that purpose. This module must be put on top of the RS485 communication board.

    

13. Drill two 12 mm diameter hole on one side of the box. Take one red banana plug and black banana plug. Insert it inside that hole, then fix it (a nuts is provided with the banana plug).

    

14. Cut 12cm of red wire diameter 3 mm. Use a wire stripper to strip 1 cm on both side of the wire.

    

15. Cut 12cm of black wire diameter 3 mm. Use a wire stripper to strip 1 cm on both side of the wire.

    

16. Take a crimp lug. Use a crimping tool to fix the crimp lug on one side of the red wire diameter 3 mm.

    

17. Take a crimp lug. Use a crimping tool to fix the crimp lug on one side of the black wire diameter 3 mm.

    

18. Connect the crimp lug side of the red wire diameter 3 mm on the red banana plug with a nut (provided with the red banana plug).

    

19. Connect the crimp lug side of the black wire diameter 3 mm on the black banana plug with a nut (provided with the black banana plug).

    

20. Take the other side of the red wire diameter 3 mm, and connect it on the Vin port of the MKR CONNECTOR CARRIER with the other side of the red wire connected to the voltage divider board.

    

21. Take the other side of the black wire diameter 3 mm, and connect it on the GND port of the MKR CONNECTOR CARRIER with the other side of the black wire connected to the voltage divider board.

    

22. Drill a 14 mm diameter hole on one side of the box, and insert in the push button. Use a nut to fix it (the nut is provided with the push button).

    

23. Connect both wire from the push button on the Grove screw terminal (one of the wire must be connect on the VCC port, and the other on the D2 port), then, screw it.

    

24. Close the box. The flowmeter datalogger is ready to be use. Be careful, the datalogger need an 12V DC power supply, use an adapted power supply.
