WiFi temperature, relative humidity, CO2 and atmospheric pressure sensor with integrated probe

Sensors with WiFi interface are designed to measure the temperature, relative humidity, CO2 and atmosperic 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 or COMET Database storage with the shortest interval of 5 minutes. The values ​​can be displayed on integrated web pages and provided to third party systems using the Modbus TCP protocol. 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 or COMET Database 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.
Thanks to these unique features, the WiFi sensor will find applications and a wide range of application areas.
