Smart Garden project aims to be a plant environment monitoring system. Thanks to a temperature and humidity sensor, we have the data on the basis of which we can implement a logic for opening the irrigation system when needed. Being a proof of concept implementation, it has not yet been used in a real garden and the condition for opening the valve is chosen for testing purposes.

Components:

* NodeMCU 32S

* Raspberry pi 4

* DHT22 - temperature and humidity sensor

* Solenoid valve - 12V, normally closed

* H-Bridge - model L298N, 12V

* Resistor 10kOhm

* Power supply adapter - 12V

* Breadboard

* Connection wires
