piSensor

This folder contains code running on Raspberry Pi with DHT11 sensor.

The collected humidity and temperature are sent to piService and shown in piClient.

Theoretically, you can use any devices with any sensors. The only thing you have to do is to send a PUT request to your piService instance.

Put request URL:

http://localhost:31414/api/local-weather/<name>/<PI_API>

Payload:

{
  "description": "<name>",
  "temp": 25.2,
  "humidity": 51.6
}

How to use

For hardware related information, please refer to Freenove DHT11 and Freenove_Ultimate_Starter_Kit_for_Raspberry_Pi as it is used in my set up.

In principle, any DHT11 or even DHT22 shuold work with the script.

Open the .env file in piSensor folder.
For now, NAME needs to be home as it is hardcoded in piClient.
Specify the PI_SERVICE_URL to your piService instance.
- For example, via the nginx gateway http://localhost:31414/api/ or directly to http://localhost:31415/.
Specify the PI_API. The PUT request can only be made sucessfully with a correct PI_API key.
- It is the same key as the one in .env in the root folder when you execute docker compose.
- Keep this key secret as anyone with this key can update the weather data.
