Wireless temperature sensor system using Bluetooth and a Particle Boron 2G/3G Kit


I am currently undertaking a project which involves measuring the temperature of a solar panel in real-time where the user can view this data on a user interface like a website or an app (from the cloud).

The temperature sensor itself (either TMP36 or something like TMP117) must be wireless. So the idea is that the temperature sensors are connected to a Bluetooth microcontroller which sends this data wirelessly to a central microcontroller (I was thinking of the Particle Boron 2G/3G Kit since it can do Bluetooth and cellular). The central microcontroller (in close proximity to the solar array ~ 30m) then sends this data via cellular to the cloud, whereby we will create a user interface (like app or website) to display this temperature.

I don’t have a strong programming/electronics background and was wondering if this was possible? Is there was a better way to do this? Or are there better devices to use that core electronics sells?

Thank you in advance :slight_smile:

Hi Mieka,

Welcome to the forum, sounds like an awesome project!

Just about everything is possible in the world of electronics, its the path that you choose that dictates how hard it will be.

For sending the data to the central-MCU (could also be called a gateway) - I’d have a look at using a mesh network configuration, Zigbee and Xbee are good contenders and are commonly used for IoT applications. Also dont let WiFi scare you off, I’ve seen on the net that the ESP32 can create a mesh network to allow other devices to connect (other ESP32’s).

Sending the data to the cloud Not my strong suit here, Adafruit IO or Blinka might be good?
