I’ve just shared a new project: “Smart Watering System”
This began as an idea after building a very basic single-channel unit. Commercial smart watering systems use a Wifi connection to the internet and get weather reports to determine the level of watering required. These systems are set up and controlled via a phone or tablet app, often you have to register with the company.
I wanted a stand-alone device based on the Raspberry Pi Pico using sensors to determine the watering required. With no need for external internet access.
