I have these two devices outside my patio door and I have no idea what they are or what they are used for. enter image description here

  • How long have you lived there? Have you ever had to let a meter reader into the house? – A. I. Breveleri Mar 9 '16 at 21:45
  • I've been in this house for about 8 months. I have not had to let a meter reader into the house. – Programmer Mar 9 '16 at 21:48
  • the one on the right looks like a sonic pest repeller. – ojait Mar 10 '16 at 2:43

    Looks like the previous owner was a big fan of monitoring weather :P – user25447 Mar 10 '16 at 21:45

The one on the left is a remote thermohydrometer. It reads the air temperature and humidity and transmits the data to a weather station.

The one on the right could be a similar device, or else a short-range transmitter that repeats one of your utility meters so the meter man can read it from his van as he drives by.

You should do a network search (eg Google) for the words written on the device.

    Or post a picture where the words are readable -- I'm curious now. – A. I. Breveleri Mar 9 '16 at 21:58
  • Thanks for the help. The first one makes sense (except I don't have a weather station). The second one doesn't make sense as it is on the wrong side of the house and about 100 ft from the nearest road. I wasn't able to read the lettering on the smaller one. – Programmer Mar 9 '16 at 21:59
  • I'll try to get a better picture but I won't be able to post until tomorrow. Also, there is at least one other small one on the same side of the house as these two. It is high up on the second floor though. – Programmer Mar 9 '16 at 22:00

    @Hooplehead24 product link to TX8U Wireless Temperature & Humidity Sensor – Tester101 Mar 9 '16 at 22:21
  • Wow, nice. Yup that's the one. Now I just need the other one. – Programmer Mar 9 '16 at 22:22

I believe the box on the right is a temperature sensor: http://www.amazon.com/GE-WIRELESS-DIGITAL-OUTDOOR-THERMOMETER/dp/B001E6DVT6.

  • That looks like the one. Interesting that there are two temperature sensors right next to each other. – Programmer Mar 10 '16 at 21:46

    Don't underestimate the weather geeks. – user19474 Mar 10 '16 at 21:47
