Best For RV: Govee Wifi Temperature Sensor With alarm

Buy on Amazon

Not everyone likes to purchase sensor for their daily purpose, but the govee wifi temperature sensor with alarm would be an anomoly. These little bluetooth sensors are like the three stooges of thermometers, always ready to entertain and keep you in stitches. It sends data to your phone either by Bluetooth (only in realtime) or if you get the Wi-Fi module, then it sends it to the cloud and your phone downloads that data and then you get historical, graphing and charting. If you add it as a sub-device for the gateway H5151, it can achieve the wifi features.

It uses one AAA battery and gets sucked dry after a month. The sensor will collect data for 20 days if lost Bluetooth and wifi connection. It should alert at a chosen interval until the alert is dismissed. They all require some degree of calibration, especially for humidity.
