Description:  1、Placed Anywhere: It can be set up and placed anywhere in a few seconds. It only takes a few seconds to add the meter to the app. You can place the magnetic backplane and metal plate anywhere.  2、Always Accurate: The sensor reliably monitors the environment. Manage temperature and humidity in the most accurate way.  3、Ingenious Design: Small size, long service life, high measurement data accuracy, built-in high-precision MEMS sensor to ensure high data accuracy.  4、Records Data: When there is no gateway, T201 records data every minute, and all data can be stored on the sensor for 20 days. Once the APP enters the working range, the data will be uploaded.  5、Powerful Function: The field of view is about 164 feet, allowing you to keep up with the latest data even on the other side of the home.    Feature:  1. The temperature and humidity intelligent sensor Sensor T201 data logger is convenient and easy to set up.  2. It can be easily paired with our mobile app (Engbird) to provide an ideal solution for monitoring temperature and humidity conditions.  3. Sensor T201 can perfectly monitor your family, children, cars, clothes, pets, fruits, cigars,  etc.  4. Free for IOS and for Android apps to monitor temperature and humidity at any time.  5. APP supports multiple languages, °C / °F mode and products with sticky base.  6. A mobile phone can be connected to multiple IBS-TH1 at the same time. One IBS-TH1 can connect to multiple mobile phones at the same time.    Specifications:  Size: about 56mmx17mm/2.20*0.67 inch;  Weight: about 20g;  Battery life: 1 year;  Wireless range: 50 meters;  Temperature range: -40~140°F (internal sensor) -40~212°F (external probe);  Temperature accuracy: typical: 0.3°C/ ±0.5°F, maximum: ±0.5°C/ ±0.9°F (internal sensor);  Humidity range: 0~99%RH;  Humidity accuracy: (25°C/77°F, 20%~80%RH: typical: ±3%RH, maximum: ±4.5%RH;  Humidity accuracy: (25°C/77°F, 0%~100%RH: typical: ±4.5%RH, maximum: ±7.5%RH;  Collection capacity: 30000 points (Maximum);    Packing List:   1 x Wireless Thermometer
