Here we are, my first complete project!I had a job, which was to monitor our beloved plant in the office. Not having a green thumb, we have resorted to the help of technology.How the project works
There are 3 sensor:
- Ambient Light Sensor = Placed on top of the plant;
- Digital Temperature & Humidity Sensor (SHT31) = Placed in the middle of the plant;
- Temperature & Humidity Sensor (SHT20) = Placed in the ground;
When the humidity is lower than the threshold, a speaker will tell us to water the plant.Cloud function
I use the Particle cloud function to show, on IoTReady platform (you can see their documentation here), all the values that the sensors capture. Also I use the Particle.plush(), this feature allows the device to generate an event based on a condition. We use this cloud function to generate a json file to create graphs with Grafana.Grafana
Grafana is a web application for interactive data visualization and analysis.
Node-red is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. With this tool we create a flow, with some rules, to make the speaker say to water the plant.
