Making a Smart Agriculture Monitoring System with LoRaWAN

Other Hardware Science and Measurement

Hi all,

This is my first post so please forgive me if there is anything inappropriate. :innocent:
We made a project to remotely monitor the soil humidity, air temperature and light conditions in agricultural settings. We utilized ESP32 Arduino IDE for development and incorporated the LoRaWAN gateway to connect to the TTN platform.

Please see detailed information about our project, along with step-by-step instructions and pictures, on Instructables:

Any suggestions would be greatly appreciated!!! Thanks in advance for your valuable opinions and feedback.

This looks like a Elecrow product demo and seems overly complicated.
Why mention the RG-02 given that the demo is using a different gateway device?

If the board hosting the sensors already has a LoRa transceiver, then you don't need a separate TTN gateway.

Not sure what you mean by "separate" gateway? Separate to what? A LoRa transceiver is not a gateway. If there is no existing gateway covering the area, then a gateway will be needed, as I understand it.

Any LoRa equipped node can run LoRaWAN software that allows it to talk to the TTN.

Yeah, if it's within the coverage of an existing gateway. If it isn't, you need a gateway. Am I missing the point here?

If the demo is trying to illustrate using a multi hop system to extend the range then that needs to be explained in the article. Currently it's using extra hardware without explaining why it's necessary.

Oh! Sorry for the confusion (RG-02), thank you for pointing it out, I have made the necessary correction.

The LoRa gateway is for establishing a connection with the TTN server. The LoRa node gathers environmental information and transmits it to the gateway, which then uploads the data to the TTN server.

Does the article make it clear that no gateway is necessary if there is an existing TTN gateway that covers the area where the sensor nodes will be placed, and how to figure out if that is the case? Gateways are expensive!

This is an application example of a gateway and node. According to our testing, only the gateway can connect to the TTN server. The nodes are for monitoring environmental data, and they send the data to the TTN server through the gateway.
