| IoT Wireless Temperature Datalogger for 4 external probes, with built-in GSM modem | COMET SYSTEM, s.r.o | GSM Datalogger is designed to record temperature from four external Pt1000 probes. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection. Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm, and analysis system. It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD, and acoustically by built-in beeper. The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable. | More | |
| 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 | |
| Web Sensor with PoE - remote thermometer hygrometer with Ethernet interface | COMET SYSTEM s.r.o. | Ambient temperature, relative humidity t-line Web sensor with Power over Ethernet feature. Remote alarm. PoE Web Sensor with built-in relative humidity and temperature sensors. Can serve as a weather sensor. High precision capacitive polymer sensor ensures excellent long-term calibration stability and ultimate accuracy. Dual-line LCD is an advantage. The power over Ethernet feature according to IEEE 802.3af is supported. Measured values are also converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy. Processing and analysis of measured data: online in COMET Cloud COMET Database software integration into 3-party systems | 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 | |
| Web Sensor - two channel remote 0-20mA inputs to ethernet | Converter Web Sensor P2520 is designed for the connection of two sensors with current output into the Ethernet network. The measured current (0-20mA or 4-20mA) can be converted to the physical quantity that is measured by the connected sensor. The converter is galvanically isolated from the Ethernet communication lines, current inputs and power supply are not galvanically isolated. | More | ||

| COMETEO Professional Thermometer Screen for Weather Station Sensor | COMET SYSTEM, s.r.o | Professional radiation shield for protection of temperature sensors or combined temperature/humidity sensors, weather monitor, and data logger. Passive, naturally ventilated. "Not only thermometer screen, but the complete COMETEO system minimizing measurement errors when used with high-quality certified sensors" The multi-plate radiation shield is used to protect weather monitor systems and provides the most accurate climate measurement results. The uniquely designed screen minimizes solar radiation reaching the sensor, minimizes radiation absorbed by the screen, and maximizes ambient airflow around the weather station sensor. The surface exposed to sunlight is made of highly reflective UV and long-term stable ASA plastic. The inner surfaces of the screen are made of matt black plastic to minimize internal reflections. The large 210mm diameter of 14 plates is designed to provide full protection of the weather sensor. Each of the fourteen black louvers is equipped with a circular slot allowing air to flow vertically through the entire radiation shield. The slot also separates the sunlit part of the louvre from the inner part and thus prevents heat transfer to the sensors. Cylindrical space with 110mm diameter and 210mm height is available inside of the plates for installation of the entire climate measuring device with minimized solar radiation. Excellent wasp and bug deterrence. Sophisticated design prevents insects from building nests inside and thus degrades measurement. Low-cost stable replacement for Stevenson screen, taking advantage of reduced maintenance and better performance due to the low time constant compared to the traditional Stevenson screen. Works with COMET instruments and most professional weather equipment. | More |
