Comet W7811 radio transmitting thermometer, hygrometer and pressure gauge
The Comet W7811 has a built-in internal barometric pressure sensor and one connector for an external temperature and humidity sensor. The Comet W7811 offers a fully wireless connection, where neither cables for connection to the internal network nor connection to a power source are required. The thermometer is powered by an internal battery that has a life of up to seven years depending on the type of use. The Comet sends the measured data via radio network to cloud storage. Here, the data can be accessed from any device with an internet connection. If you are interested, we can provide you with a calibration certificate for the meter. Simply choose the appropriate external probe and select the calibration option. More

Functions of the Comet W7811
- Possibility to connect an external temperature and humidity sensor with a length of up to 30 metres.
- Wireless transmission of measured data via Sigfox radio network. The network has coverage throughout Europe. You can check the current availability at your location on the coverage map. Alternatively, the signal must be provided by the own BTS station (in related products).
- From a computer or mobile phone with internet connection, you can easily access the measured data via the Comet Cloud online storage.
- Comet Cloud offers comprehensive features and services for managing and analysing measured data, including remote communication with sensors. As an example, let's mention information about the battery status in the sensor, setting minimum and maximum values at which the system sends an alarm email.
- Extended warranty 3 years.
