The TR4A series enables data collection and management using dedicated mobile device applications. Data recorded by the logger is sent to the mobile device via Bluetooth Low Energy, which can then be transferred to our free cloud-based "T&D WebStorage Service" using WiFi or cellular network. The all-in-one sensor for TR43A has a temperature measurement range of 0-55°C and can measure humidity from 10 to 95％RH. The body itself has an IP64 rating* and can be used in environments of -40 to 80°C.
*Note that the temperature-humidity sensor is not water resistant.
