James Nelsen
Order Sensor

I ordered the above sensor and received it promptly. I learned I had ordered the wrong one and have returned it for credit. I was very happy with your service.

Clay Wedan
Limited life of sensor

The sensor lasts about 3 years before failing to emit a signal. The batteries last anywhere between 1 and 2 years. If your outdoor temp and humidity readings stop showing up on your device then buy a new sensor.
