When using external power, the data logger itself generates heat and the internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case. *2: When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C. *3: Client function. HTTP(S) proxy supported. *4: Bluetooth will be used to make settings and view data on iOS and Android devices with the mobile app (to be available within 2021). *5: When using external power, the internal temperature of the logger rises. *6: Battery life varies depending upon multiple factors including frequency of communication, LAN environment, ambient temperature, recording interval, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life. The specifications listed above are subject to change without notice.
