Description: Material: ABS Power supply: AAA1.5V * 2 (excluding battery) Wi Fi support: 2.4G IEEE 802.11 b/g/n Temperature measurement range: -10 C~55 C Temperature accuracy: 0.3 Humidity measurement range: 10%~99% RH Humidity accuracy:+3% RH Specifications: Product features: 1. [WiFi+Bluetooth Dual Mode]: Faster connection to the network. Connecting to the network is twice faster than only WiFi 2. [High temperature and low temperature alarm]: Once the set temperature value is exceeded, the phone will prompt an alarm 3. [High humidity low humidity alarm]: Once the set humidity value is exceeded, the phone will prompt an alarm 4. [Real time monitoring]: Battery powered AAA1.5V * 2 (excluding batteries), low power consumption, according to system default settings, can be used for approximately 1 year. The data update frequency is 1-120 minutes, and you can choose the update frequency as needed. The smaller the value, the shorter the actual battery usage time will be 5. [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 6. [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 7. [Scene linkage]: This sensor can serve as a temperature and humidity data source for graffiti intelligence, smart living, Amazon Alexa, and Google Home. You can perform many automated processes based on the data source. Please note that this function requires a universal infrared remote control or WIFI on-off device to be used. You can contact customer service to purchase 8, [Temperature Unit Switch}: The sensor design has a conversion function between Celsius and Fahrenheit temperatures. You can choose the units to display as needed. The speed of the switch is related to the set data update frequency. You can first select the update frequency for one minute, and then switch the temperature to the new unit, and then switch the data update frequency to the time you need. 9. [Third party voice support]: The sensor supports Amazon Alexa Google Home Assistant. You can hear the current temperature and humidity through voice. Note: 1. To achieve linkage function, if used in conjunction with air conditioning, a universal infrared remote control can be used to achieve linkage. If combined with a humidifier, it can be combined with a zigbee on-off device to achieve linkage. 2. Bluetooth is only used for network signal connection and cannot be used alone. WIFI+Bluetooth is more stable Package Included: 1 * Temperature and humidity Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-DIMEANI official store
