  19. In-lab: Make sure the sensors node is connected to the cell network. Ask administators to connect it if it's not. If doing this by yourself then follow the next steps: Step1: Check for "Active" on the Twilio website. Use the MEID to search the SIM repositoy on Twilio. If it's active then you are done.

    • Step 2: If the search on Twilio did not return anything then check the Node has a SIM card. If yes, then check and update the 'SIM-Node ID pairings' spreadsheet here. If the Node does not have one, get a SIM from an admin and fill in the spreadsheet linked above.

    • Step 3: After the node gets a SIM card and the infomation is logged in the 'SIM-Node ID pairings' spreadsheet proceed to activate the SIM card. You will have to log into the Twilio website and activate it. Consult the attached picture to see how the setting should be set.

    • Unique Name = Node ID (i.e PTK001). If the Node ID is already taken then doulbe check the ID parings here. If it's all good, then edit all the Twilio unique names accordingly.

  20. Insert a fully charged battery into the sensor node. Plug in the battery before the solar charger. Make sure the battery leads are wired correctly. The terminal block and leads are shown here. A green LED light on the cell modulem should  turn on.

  21. Make sure that there is an O-ring on outside of the node. make sure to tighten the screw on the inside snuggly. Make sure the wires are connected in this manner. From the edge it should be "black, red, white". The ultrasonic sensor has labels on it and GND (ground) is  on the very end. Hence, the black wire on the end.

    • The other ends of the wires are connected to a 5-prong terminal block. That terminal block should be connected to the board at the following pins: P12.3 : White wire, P12.4 : Red wire, GND : Black wire.

  22. Make sure all the jumpers on the board are connected properly.  They are labeled JP1 and JP2 can use the mnemonic "top-down, bottom-up".

    • can use the mnemonic "top-down, bottom-up".

    • Another view.

    • These jumpers should be disconnected when ready to deploy. This is done to save battery.

  23. The Node ID is determine by the location where the node will be deployed. Ask and administator where to deploy. Then, find all the site details here.These include site visits, pictures, addresses, and notes. Ask admin to do this step. Alternatively, ask admin for the scripts that assigns the Node ID and the reporting time interval. Assign both using the Anaconda Navigator's Jupyter Notebook feature. You will need the sim card's MEID  and the desired Node ID to do this. The google drive has a spreadsheet with MEID's and Node ID's here. Keep this updated.

    • Set the reporting frequency to 5 minutes!

    • Once assigned, the readings will be pushed to Grafana. To double check that it was assigned successfully you can consult the 'Tables' Dashboard on Grafana. Ask administarator for Grafana credentials.

  24. Assumption: you have the Grafana credentials. Use an existing Dashboard (i.e. Abhis Hostage Nodes) or create one. To enter the edit panel click the header and it will appear. If you created a new dashboard, then you must create a 'v_bat' panel and a 'maxbotix_depth' panel. They should be labeled to indicate  battery voltage and depth. Always save changes frequently.

    • Once inside the edit panel: It's possible to edit an already existing entry and only update the Node ID and alias. Alternatively can click on 'add query'. When adding a new query get an admin to supervise while you do it.

    • Use this dashboard exclusively for testing and delete already deployed nodes. Sensors that have been deployed should be promoted to their permanent Grafana Dashboard. i.e: Cinton River, Huron River,...

  25. Click on the nodes INDIVIDUALLY to see that the reported values are sensible. If the depth reading is -1 then there is an ultrasonic sensor problem. If the depth value is 0, then the ultrasonic sensor does not have  0.5 meters of  required space between itself and what it's reading. Node must report successfully for 12 hours

  27. Make sure to take all required tools. The tools required should be deduced from the site visit inspection and notes corresponding to the location.
    • Make sure to take all required tools. The tools required should be deduced from the site visit inspection and notes corresponding to the location.

    • The van already has a tool kit. The google drive has a document specifying which tools belong in the van.

    • Collect hardwarespecific to sites, enough fully charged batteries for nodes, at least one fully charged 12v battery, enough locks, and drinking water.

    • Hardware inlcude strut channel, bolts, nuts, brackets, C-clamps, etc.

  28. Upon ARRIVING to every site, fill this google form.
  29. After the node is deployed and there is no interference from it being hadled, wait for a reading.
    • After the node is deployed and there is no interference from it being hadled, wait for a reading.

    • The reporting frequency should have been set to 5 minutes! As required in step 21 of this guide.

    • If the reading doesn't appear or it's -1, then reach out to someone in lab to reassign a working node to that location. Take the faulty node back to lab. Donnot diagnose in the field.

    • Assumption: You brought extra working nodes.

    • Requirement: Bring extra nodes.
