Communication Interfaces Wireless LAN Communication : IEEE 802.11b/g/n (2.4GHz only) Security: WPA/WPA2-PSK(AES/TKIP) WPS 2.0: Push Button Configuration Protocol (*3): HTTP, HTTPS, DHCP, DNS Bluetooth Communication (*4): Bluetooth 4.2 (Bluetooth low energy) USB Communication: USB 2.0 (Mini-B connector) Power (*5) Battery: AA Alkaline LR6 x 2, AA Ni-MH x 2 External: USB Bus 5V 200mA, AC Adaptor AD-05A2 or AD-05C2 Battery Life (*6) Approx. 10 days (when Auto-upload interval is 1 min) Approx. 1 year (when Auto-upload interval is 1 hr) Approx. 15 months (when Auto-upload interval is 12 hr or more) Dimensions H 58mm x W 78mm x D 26mm Weight Approx. 55g Operating Environment Temperature: -10 to 60 °C Humidity: 90 %RH or less (no condensation) Accessories Temperature Sensor (TR-0106) x 2 Temperature/Humidity Sensor (THA-3001) x 1 High Precision Temperature/Humidity Sensor (SHA-3151) x 1 AA Alkaline Battery LR6 x 2, Registration Code Label, USB Mini-B Cable US-15C, Manual Set (Warranty Included) *1: When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C. 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.
