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 - Connection wires
