An pretty much finished IoT project where a data logger for a greenhouse is being developed.
The basic concept is as follows:
- An ESP32 microcontroller will meassure the temperature and humidity of the inside of the green house every 20 minutes.
- In between readings, the microcontroller will enter hiberation to save battery. A timer will wake the microcontroller from hibernation.
- Every reading is send to a LAMP server hostet on a local Raspberry Pi.
- TODO: The data will be accessible from the LAMP server via an interactive website, which will show plots of the data.
