| WiFi temperature, relative humidity, CO2 and atmospheric pressure sensor with integrated probe | COMET SYSTEM, s.r.o | Sensors with a WiFi interface are designed to measure the temperature, relative humidity, CO2, and atmospheric pressure with a connected probe (included in delivery). Communication with the sensor is done via a wireless WiFi network. The device allows sending measured values to the online COMET Cloud (with the shortest interval of 5 minutes) or into COMET Database. The values can be displayed on integrated web pages and provided to third-party systems using the Modbus TCP, JSON, and XML. The measured values are displayed on the LCD display. The device continuously evaluates the alarm limits of the measured values and in case of exceeding them, it can send an e-mail or inform by means of acoustic or optical signaling. Two-alarm limits are supported for each measurement channel. The main advantage of sensors with WiFi interface is the simplicity of deployment in places where WiFi infrastructure is already available. Just place the sensor in the desired location and connect it to the WiFi network. WiFi sensor in conjunction with COMET Cloud offers a comprehensive solution for monitoring and alarm without the need for a server solution on the part of the user. If necessary, however, the sensor can also be connected to third-party systems, either using the Modbus TCP protocol or by sending JSON data to an HTTP server. Sensors allow providing values via XML and JSON using HTTP GET requests as well. Thanks to these unique features, the WiFi sensor will find applications and a wide range of application areas. code W4710 | More | |
| Wireless thermometer, hygrometer, Sigfox IoT | COMET SYSTEM s.r.o. | The device measures the temperature and humidity from the built-in internal sensor. 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). Highlights: wireless transmission of measured values and alarm status 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 | More |
