DIY Remote freeze Alarm
Here is a drawing of a remote temperature alarm you can make yourself.
You need a rain bird rain/freeze sensor a 24VAC relay a 3 way switch and a 24VAC buzzer/light. Some wire a terminal block and a box to put it all in. I think I got the wiring right. COM=common. NC= normally closed. NO= normally open. Feel free to ask any questions and for sources of the things you will need. Remote Temp Sensor r.jpg |
