Hi, I was wondering whether I could use opengarage just as a water tank level sensor. For example, put it at the top of my home water tank in order to monitor the water level. What kind of waterproof enclosure should I use?
Could the above be an alternative use of opengarage? I’ve been looking for a water level sensor for awhile but all options seem to me very expensive for home use.
Many thanks

Yes, I think this is a great alternative use of OG — a while back I saw a project here:
that uses the same ultrasonic distance sensor for sump pump monitoring.I think the stock OG firmware can already be used as a water level sensor — you can set the threshold to an appropriate value you want, and you can change the mount from ‘ceiling mount’ to ‘side mount’ if you need reverse logic.
Thank you Ray,
where could I find the technical specification of OG board. What is the voltage output of relay?
Can I use the on-board relay to switch on/off for example a water pump?
Great product!
SotiriosOpenGarage is completely open source, you can find the circuit design at:
https://github.com/opengarageI am not sure what you mean by ‘the voltage output of the relay’ — the relay does not output any voltage itself, it’s a switch. The on-board relay is rated 3 amp contact current. If your water pump exceeds 3 amp, you should NOT use the on-board relay but you can use an external relay with larger current rating, or solid state relay.
