【USB Rechargeable Battery】Under the ambient temperature conditions of 25℃/77℉, when the logging interval is 60 minutes (settable on the app), the built-in 500mAh rechargeable battery can continuously work for six months after a full charge, eliminating the trouble of frequent battery replacement. Please note that battery life will be affected if the device is placed in a lower temperature environment close to 32℉ and below.
【Comfort Level Emoticon】We can customize comfort ranges of temperature and humidity on the App and directly understand if the current temperature and humidity are healthy for our family and pets through the comfort level emoticons on the screen. Moreover, we can connect the sensor with Alexa and ask for temperature and humidity by voice at any time.
【Clear Display】The LCD screen is spacious, making it easy to view both the current temperature and humidity simultaneously. Emoticons indicating comfort levels offer a quick way to assess family comfort. With a sampling rate of every 10 seconds and continuous syncing with the display, the device provides up-to-date temperature and humidity readings.
【Precise Swiss Sensor】It adopts precise temperature and humidity sensors made in Swiss, premium and sensitive, ensuring accurate temperature measurement of ±0.3℃/±0.5℉ and a humidity accuracy of ±3%RH. It supports a Temperature Measurement Range of 0℃~50℃ / 32℉~122℉ and a Humidity Measurement Range of 0%RH~99%RH.
【Smart Alert Function】It supports high-and-low temperature/humidity alerts and low battery alerts. We can set temperature and humidity alarm values on the INKBIRD App. When the detected temperature/humidity exceeds the preset safe range, or the device battery is too low, we will receive notifications from the INKBIRD app in time.
【Stay Connected Anywhere】This sensor can be controlled from a smartphone via a 2.4GHz WiFi connection, connecting directly one-to-one without needing a WiFi gateway. Moreover, one smartphone can simultaneously control multiple sensors, and one sensor can be monitored by many smartphones at the same time.
