Can I use this as an ATO?

[MoshJosh]

This is a “security” system, but if I already have a pump and reservoir can I just use this as an ATO sensor?

Seems reasonable to me, but I would also install a float valve for redundancy. Only cost you another $10-15 and you will sleep better at night knowing there is a mechanical fail-safe to prevent the tank over filling and crashing if the optical sensor fails.
