This project will give an insight in the area that is the internet of things (IoT) as I explain what I've done and what choises I've made for this project. The plant communicator project will gather sensor values once every half hour or when a button on the board is pressed and send them to an online platform for data storage and presentation. Over time I'll get to know the plant's needs as light, relative airhumidity, moisture of the soil and room tempature is measured. The plant communicator will also notify when something isn't right. I'll discuss components, code, platforms and scaling factors. This project should not take long to assemble, maybe a day.
Material
In order to replicate the project some sensors and a device able to connect to the internet is needed. I bought the sensors and Pycom devices from Electrokit.se and the rest I took from the Arduino starter kit. Estimated total cost: 62 €
DHT11 tempature and humidity sensor (Electrokit)
Photoresistor sensor (Electrokit)
DIY moisture sensor
