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
