My cellular based sensor, open to extra ideas

1

Hi everyone,

I hope that I placed this topic in the right category. I’m Daan Pape, the creator of the Walter module (https://www.quickspot.io) and Walter Feels carrier board. I’m currently working on creating cool use cases for our module and that is how I found out about this sensor community. I immediately made a setup with an SPS30 sensor from Sensirion and connected it to Walter to transmit measurement data, you can see the results here: Walter ESP32-S3 NB-IoT/LTE-M/GNSS

Of course I now need to upload the data to this community’s servers. But I was wondering which other sensors could be interesting to connect? I was thinking of maybe a geiger counter but I could not find which one would be good.

Please let me know your thoughts,
Best regards,
Daan

Welcome !

The Geiger Counter is already in the SC server through Multigeiger – Ecocurious

You can connect it to your system.

You could also programm a system to transmit data from our noise sensor.

Do you have a Github for your code ?

Here what I have done for now for Aircarto but it is a bit paused:

Thank you for your prompt reply. The Geiger counter looks very cool. All my code is on github:

I will checkout the Geiger counter and noise sensor. I would definitely like to add them to my test setup.

I wrote a Java application that accepts sensor data from nodes in TheThingsNetwork (temperature/humidity, particulate matter, noise), converts it, then interacts with the sensor.community API to send it. Basically it just emulates a node sending a HTTP request for each measurement item.

You’re not using LoRaWAN, but I suppose the mechanism is very similar: you receive or pick up the data from the IOT network backend, then do conversion and finally forward it to sensor.community. Each sensor still has to be registered manually at https://devices.sensor.community/ with the correct sensor types. You will need to provide a unique sensor id when registering a sensor, that id will also be part of the device sensor data upload.

You can find my code at: GitHub - bertrik/sensor-data-bridge: Bridge software for receiving airborne particulate matter measurements from TheThingsNetwork and forwarding them to sensor.community and opensensemap
