W1209 temp Relay Switch Module

Finally arrived! Didn’t get a chance to use it yet. A bit smaller then I imagined which is awesome. It will take up less room and still do what it’s supposed to. Looking forward to using this in my DIY mini freezer build.

Just arrived today. Looking forward to setting it up for my baby chicken coop project.

I bought one with a green display. It's super bright for a display but easily readable. It's simple to set the temp and the temp probe is good quality. Pros- good quality bord. Bright display and nice red Led to indicate the relay is on. Standerd operating voltage (12v) but it can also run at 5v witch makes it useful for portable projects. Notes- this thing only desplys in celseous Instructions are in Chinese Need to look up how to acses all the functions. The display is Soo bright I'm afrade the life span of the LEDs in the display won't be long. Cons- the cenector for my temp probe was broken. This thermistat can not safely switch mains voltage as the isolation from the switched lines to the rest of the sercutry is not good enough clearens. Would advise to have this configured so it switches a proper large relay if you're going to be switching mains with this device. Relay runs worm. Conclusion- it's desent quality and good for use with you're projects but configured it to switch a external relay if you're switching mains But don't detectly switch mains with this device.
