Swiss Precision Sensors: Each ITH-11-B has a built-in professional-grade temperature and humidity sensor that samples every 3 seconds to give real-time feedback of temperature and humidity; Supports temperature ranged from -40 to 60 °C (-40 to 140 °F) with high accuracy of up to 0.2 ℃ (0.36 °F) and humidity ranged from 0% to 99% RH, accurate to 2%

Bluetooth and WiFi Connection: Each sensor uses the advanced Bluetooth 5.0 and can be controlled within an open distance of 80 m/262 ft, and the gateway enables you to remotely control and monitor from anywhere via WiFi. With the gateway, you can link up to 10 Bluetooth sensors at once to keep an eye on every room in your house

Super Long Battery Life: Two AAA batteries are included with each temperature-humidity sensor. The 1200 mAh high battery capacity allows the sensor to operate continuously for up to nine months, providing 24/7 monitoring of temperature and humidity without the need for frequent battery changes

IP65 Waterproof Sensors: The compact and lightweight design, along with the IP65 waterproof function, makes every sensor suitable for use in both indoor and outdoor environments, particularly in narrow spaces, such as homes, baby rooms, refrigerators, reptile terrariums, greenhouses, wine cellars, courtyards, and RVs

Smart App Functions: View the data graphs on the app to gain insight into the changes in temperature, humidity, VPD and dew point. With a WiFi connection, you can receive instant notifications of high and low temperature alarms, high and low humidity alarms, and low battery alarms from the app, no matter where you are

Data Storage and Export: The thermo-hygrometer can save up to 300 days of offline data, while the gateway can store 1-year historical data in the cloud. Furthermore, the smartphone app can save an unlimited amount of historical data, which can be exported via email. The interval for data recording can be set to 1, 2, 5, or 10 minutes, according to your needs
