A. Remote monitoring and real-time data recording: The WiFi thermometer can perform real-time monitoring. You can preset temperature and humidity values in the "Scenes". The thermometer is compatible with Tuya Smart, Smart Life, Alexa, and Google Smart Home systems. Historical temperature and humidity data can be saved for about 2 years. B. Smart linkage: When there is a change in the environment, smart linkage at home can be achieved. For example, if the ambient temperature exceeds 35°C, the air conditioner may automatically turn on; or when the humidity is below 20%RH, the humidifier may start spraying. C. Voice control: You can query temperature and humidity information through Alexa or Google smart speakers. With one click, you can share the device monitoring information with your family so that they can also monitor the environment. D. Precise measurement: The temperature and humidity sensors have relatively high precision and sensitivity. The temperature measurement range is from -20°C to 60°C, and the humidity measurement range is from 0%RH to 100%RH. The temperature measurement accuracy is about ±1°C, and the humidity measurement accuracy is about ±5%RH. Moreover, this wireless temperature and humidity monitor updates data about every two minutes to ensure a certain level of accuracy. E. Compact size: The WiFi temperature and humidity sensor has dimensions of 71 x 25 x 20 mm, which saves space and is easy to carry. It is small enough to fit into small spaces such as potted plants, cigar humidors, and reptile terrariums, meeting various usage needs. It can run on a battery for about 1 year.
