Irrigation valves and relays - hydrosys4 

Thanks! This has been a great help for my gardening irrigation project.

Enjoy your content! One of your other videos inspired my solar panel rpi irrigation school project. Very helpful!

Thanks for your nice video, very clear. May I ask what was the purpose of the bpard with keys that you attached to the pi? And what was the name of android app?

Instead of a valve, is it possible to use a pump for smaller indoor applications?

Is there a gradual water valve? where you can control how open it is 0-100% ?

Ciao, sto provando a collegare un relè identico al tuo, comandato da Raspberry ad una elettrovalvola 12v nc di quelle piccole bianche , quando eccito il relè l'elettrovalvola si apre, però poi tutto il circuito rimane bloccato , valvola aperta e relè eccitato, hai riscontrato problemi di questo tipo?

well done!

What is that awesome little screw-down terminal block?

It makes me wonder, why people use this crap, bunch of strange boards? Take normal PLC like Siemens LOGO (230V AC or 12/24V DC), simply connect wires. In soft you can make those relays as required for device
