    WiFi Remote Monitoring and Custom Alerts

    After connecting this thermo-hygrometer to your phone via 2.4GHz WiFi, you can monitor temperature and humidity anytime, anywhere on the INKBIRD app. You can also set high and low thresholds, and get notified if those limits are hit or the battery runs low.

    Swiss-Made High Precision Sensors

    This monitor adopts high-quality Swiss temperature and humidity sensors, precise and responsive, providing accuracy of ±0.3℃/±0.5℉ and ±3%RH. It measures temperatures from 32℉ to 122℉ (0℃ to 50℃) and tracks humidity levels from 0% to 99%RH.

    Large LCD Screen with Comfort Level Emoticons

    The sensor samples temperature and humidity every 10 seconds and displays the results on the screen in real-time. Next to the readings are comfort level emojis, and the comfort ranges are customizable through the app.

    USB Rechargeable 500mAh Battery

    At room temperature of 77℉/25℃ and with the default recording interval of 60 minutes, the IBS-TH3 WIFI PLUS can last for about 3 months. If you adjust the interval to 120 minutes, the battery life will be extended to 6 months.

    Frequently Asked Questions

    Can I use the IBS-TH3 WIFI PLUS for outdoor conditions?

    The IBS-TH3 WIFI PLUS is primarily designed for indoor use, but it can still work in semi-outdoor environments, such as covered patios or greenhouses, provided that it is protected from direct exposure to rain, snow, or extreme temperatures. Ensure that the device is stored in a cool, dry place to prevent damage.

    Can I connect multiple IBS-TH3 WIFI PLUS to one account?

    Yes, the INKBIRD app allows you to connect multiple sensors under a single account, which is particularly useful for monitoring different areas simultaneously. Plus, one sensor can be monitored by multiple accounts or smartphones at the same time.

    Does the IBS-TH3 WIFI PLUS have a screen backlight?

    No, the screen of IBS-TH3 WIFI PLUS does not support backlight.

    Can IBS-TH3 WIFI PLUS be used in refrigerators and freezers?

    We do not suggest this thermometer and hygrometer for use in refrigerators and freezers, as it is not waterproof. Placing it in those environments could affect its performance or even cause damage. Plus, the cold temperatures will drain the battery much faster.
