WiFi temperature and humidity: [WiFi+BT dual-mode]: Connect to the network faster. Connecting to the network is twice as fast as WiFi only [High temperature and low temperature alarm]: Once the set temperature value is exceeded, the phone will prompt an alarm [High humidity low humidity alarm]: Once the set humidity value is exceeded, the phone will prompt an alarm [Real time monitoring]: Battery powered AAA 1.5V * 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 the update frequency can be selected as needed. The smaller the value, the shorter the actual usage time of the battery.
