TP-IOT

Configuration

I created a node API with Typescript and Javascript framework Express.JS.

This app collects humidity and temperature data generated by sensors, thanks to node app in folder tp-iot-main.

1. Open a terminal and install dependencies into the root folder and tp-iot-main folder :

npm i

2. Then, create a new .env file based on .env.sample.txt and modify what you need

3. My node app runs with a Typescript compiler who transform Typescript in Javascript(ts-node), so you have to start a terminal and write :

ts-node index.ts

Final Results

You have in graphs pictures some screens in Grafana, and InfluxDB Data Explorer.

In Grafana I add some threshold, it's a value that you specify for a visually crossing in your dashboard.

For Temperature, threshold orange color is for 28°C and red for 30°C.

For Humidity, threshold orange is for 80% and red for 90%.
