Specification AgeRangeDescription : General BatteriesRequired : 1 Brand : ORIA BulletPoint1 : 【APP Control & Smart Alert】Download the APP to monitor temperature and humidity. When the data exceeds your preset value, the data on the APP will turn red and send a buzzer alert to your phone. BulletPoint2 : 【Custom Settings Data Storage & Export】You can set the record start time and record interval time of the log, total up to 600 days of data is stored internally in the device. You can also export historical records in batches and view data analysis chart. Note: You need to manually turn it on after the setting is completed. BulletPoint3 : 【Wireless Connectivity & High Precision】The Bluetooth thermometer hygrometer uses a high-precision MEMS sensor to provide a connection distance of up to 50m/164ft (without obstacles). Temperature range: -20-65℃(-4-150°F), accuracy: ±0.5℃(±1℉); Humidity range: 0-100%RH, accuracy: ±5%. BulletPoint4 : 【Battery Powered & 2 Mounting Options】The thermometer and humidity gauge is powered by 1* AAA battery(not included). A hanging hole is designed for various placements you want, it can also be adsorbed on the surface of metal objects such as refrigerators. BulletPoint5 : 【Note】Once the data storage capacity is full, it will keep the stored data until you transfer it out of the device. Before manual initialization of new records, the recorder will not continue to store new data. You need to regularly synchronize recorded data before the logger reaches Max capacity, and start a new log record in time. You must manually set up and re-record it when it is full, otherwise it will not be automatically overwritten.
