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
