Dissolved oxygen sensors


Solar Power

- if using 10kw (least likely):     - inverter is able to connect via WiFi (shine wifi) to the computer where data can be read     - power being supplied     - input     - info from BMS - if using the 500w portable system:     - can check the battery capacity    - other features? Waiting for email back

Measuring power (breakout board that can connect to "arduino" and send by LoRaWAN):

INA219 I2C Digital Wattmeter Bi-Directional Current Sensor Voltage Measurement Power Supply Sensor Breakout Module:

Light Spectrum (including UV radiation)

And in general, light spectrum (will be affected by scattering by polution, can change grow of flora). Many sensor available. Cheap.

Power etc. For oysters: - bubblers/ air pump (low voltage)

- power for the sensors (above)

Wireless Environmental Sensing Platform

LORAWAN technology

a) Netgear 4G LTE connection with Ethernet, with NETGEAR Nighthawk M2 (MR2100) with public IP.

Set and forget

SenseCAP Industrial Environmental Sensing Kit

b) Wireless: NEW SCHOOL, working out of the box, without code: LoRaWAN nodes:

B) LoRaWAN gateway:

Provided by Seeedstudio: SenseCAP M1 LoRaWAN Indoor Gateway - US915 (connect to the Netgear 4G router)

c) Wired OLD SCHOOL, for hacking learning and teaching. Arduino, grove


Seeedstudio LoRaWAN gateway is compatible with Helium Longfi network, and this is supercool:

"People’s Network is the world's first peer-to-peer wireless network that provides a secure and cost-effective way for low-power Internet of Things devices to send data to and from the Internet."

Helium ecosystem:

Question: should we run our own network server?

Cloud services, data gathering, visualization, sharing:

The data you collected can also be visualized in real-time and integrated with 3rd party platforms such as Datacake and Ubidots, and others:

Environment Monitoring


Measuring H2 (production)

- only need to check the voltage being supplied to the cell (suggest a way to do this?) - measuring volume of H2 by using mylar balloons (analog, imprecise measurement) - is there a way to measure the gas flow rate through the output pipe?

Note: voltage supplied to the cell? pipe? not sure what measurement is needed and where. Disolved H2? or atmospheric H2? In any case, H2 sensors for air exist (I have). Example:


No salinity sensors on Seeed, can use TDS sensor for water quality instead

Salinity is basically measured by measuring conductance, but they use fancy platinum electrodes to avoid corrosion, etc. Example at DFRobots:

Note: we can make our own without electrodes (inductive conductance):

TDS (total dissolved solids)

temperature (can connect with the lorwan?) Will be underwater. Current sensors offered may not be suitable (why?)

IR thermometers are out of stock

Note: temperature sensors (underwater or otherwise), analog or digital, are very simple to find and setup. I can atest +/-0.1C from -10 to +85C using for instance the digital thermometer DALLAS 18B20. It's a one-wire interace, with only two wires we can daisy chain dozens if one wants a temperature front.

Note: an IR thermometer would only measure the temperature of the water SURFACE.


Air quality sensors: Airnote

Connects directly to servers, use the API to see data, uploaded to safecast automatically

Built in cellular data

Autonomous power with solar panels, optional USB charging

Question: why use another API, or cellular? why not use the same Helium network and LoRaWAN? the sensor itself (air quality) is just another analog/digital sensor. We can hack the senseCap, or better, Seeedstudio may do this for the project.

Atmospheric humidity?
Other sensors including...

Sound? (underwater mic). Sonic polution may be important?

In any case, the cost of adding sensors is negligeable.


Measurement of dissolved OXYGEN in water?

Isn't that important for plankton and fishes, etc?

In the air: from seeedstudio:

bacteria ecoli

not using sensor.

Note: why not using sensor? there are sensors for that, probably very expensive:

  • fridge (250W max, standard 120v)
  • h2 cell
  • lights (home use philips lights on blog might allow for dimmable remote control)
  • EL wire (no IOT as far as I know)
  • DNA sequencer (can data be transferred from this?)
  • microscope (basically just an LED with some lenses, so low power use)
  • Aquarium heater/cooler (if possible: set up a thermostat system to maintain the temp within a threshold, can use a microcontroller)

General notes:

Connectivity: verything can be connected to the network, i am not sure i understand those questions - i guess it means "connect out of the box"?

Government: Framework

Companies, farmers: Knowledge output, Profit
