Product Details The device measures the temperature, humidity and atmospheric pressure from the built-in internal sensors. It is characterized by a simple compact design with the possibility of installation directly into the measured space. The sensor can be used with a suitable sensor cap even in more demanding conditions. The measured values are sent in an adjustable time interval (10 min to 24 h) by radio transmission in the Sigfox network to the COMET Cloud, from which the user can view them using a personal computer or mobile device. The instrument can monitor up to 2 alarm limits of the measured variable. Exceeding these limits is indicated by sending an emergency message. COMET Cloud transmits this alarm message via e-mail to the selected user. The device is suitable for applications that tolerate the delay of information delivered by Sigfox (max. 10 min). wireless transmission of measured values and alarm states battery power with low battery indication (battery life 4 months to 7 years) external power with optional accessories remote setting of the device from COMET Cloud (maximum once a day) IP65 traceable calibration certificate in accordance with EN ISO / IEC 17025 The availability of Sigfox network in a particular location Check your Sigfox network availability before you buy your device. COMET devices in the Sigfox network can be used anywhere in the RCZ1 zone. Learn more about Sigfox (RC) Radio Zones.
