Features: *[WiFi+Bluetooth Dual Mode]: Faster connection to the network. Connecting to the network is twice faster than only WiFi *For temperature and humidity，for product needs to be used with for Tuya for zigbee3.0!!! *[High temperature and low temperature alarm]: Once the set temperature value is exceeded, the ph will prompt an alarm *[High humidity low humidity alarm]: Once the set humidity value is exceeded, the ph will prompt an alarm *[Real time monitoring]: Battery powered AAA1.5V * 2 (excluding batteries), low power consumption, according to default settings, can be used for approximately 1 year. *[Temperature and Humidity Curve Graph]: Record the temperature and humidity changes on the APP and present them graphically for you. More intuitive to let you know about recent data changes *[Multiple installation methods]: It can be placed directly on the table or pasted on the wall. Without a data cable, it's more convenient and beautiful *[Scene linkage]: This sensor can serve as a temperature and humidity data source for graffiti intelligence, smart living， You can perform many automated processes based on the data source. Please note that this function requires a infrared remote control or WIFI on-off device to be used. You can contact customer service to purchase *[Temperature Unit Switch}: The sensor design has a Celsius and Fahrenheit temperature conversion function. You can choose the unit to display as needed. The speed of switching is related to the set data update frequency. You can first select the update frequency for minute, and then switch the temperature to the new unit, and then switch the data update frequency to the time you need * [Third party voice support]: You can hear the current temperature and humidity through voice.
