Smart WiFi Monitor for Indoor Climate

The INKBIRD IBS-TH3-PLUS is a WiFi thermometer hygrometer designed for homeowners who want remote visibility of indoor conditions. It connects directly to a 2.4GHz network without a separate gateway. A single smartphone can manage multiple sensors, and several phones can view the same unit simultaneously. The device includes a rechargeable battery charged via USB cable.

Suits Remote Monitoring Not High Precision Lab Work

This sensor suits users who need app alerts when temperature or humidity drift outside set limits. It also fits families who want a year of history exported as CSV files for review. Buyers requiring laboratory grade accuracy or an industrial calibration certificate should look at specialised instrumentation instead. The comfort emoticons on the LCD give a quick visual check for everyday comfort.

Covers Typical Room Range With One Year Logs

The unit measures temperature from 32 to 122 degrees Fahrenheit and humidity from 0 to 99 percent RH. Stated accuracy is ±0.3 or ±0.5 for temperature and ±3 percent for humidity. Readings update every 10 seconds on the display and in the app. Data storage holds a full year of records before older points are overwritten.
