WiFi Temperature, Humidity, CO2, and Pressure Sensor with Integrated Probe
Comet WiFi sensors are designed for autonomous measurements, processing, and alarming of the physical quantities. Measurement of temperature, relative humidity, barometric pressure, CO2 concentration are supported. Inputs and measurement ranges depend on the model and cannot be changed by the end-user. Device communication is done via a WiFi wireless network. The device needs to be powered from an external adapter, which is part of the shipment.
Online Wireless Measurement and Monitoring
- Temperature
- Humidity
- Dew point
- Atmospheric pressure
- CO2
Sensors with a WiFi interface are designed to measure temperature, relative humidity, barometric pressure, and CO 2 concentration of the air in a non-aggressive environment. Communication with the sensor is done via a wireless WiFi network. The instrument measures with 1sec interval and the shortest sending interval to COMET Cloud is 5min. Indoor applications are the most suitable for sensors with a WiFi interface. It is extremely easy to mount them on monitored places and run them. The measured values are displayed on the LCD display and can be sent to the COMET cloud or COMET Database software at set intervals.
Alarm Indication
- Exceeding alarm limits on the channel
- Device failure
- External power failure
For each measurement channel, an upper and lower limit can be set. In case the limits are exceeded an alarm is indicated on the display, visually by LED or acoustically. The COMET Cloud or COMET Database software can create an alarm in an e-mail and send it to the user. SMS alarm text is also possible with database software and with proper accessories.
Connect the Device to WiFi Network for Settings
Adjustment of settings, through the sensor´s web browser interface, is simple and without the need for special software. The sensor must be connected to the Wi-Fi network to enable web settings and configuration. Enter the IP address of the sensor into your internet browser, load its website, click on ‘Settings’ and adjust the settings. The sensor setting can be also done via USB cable from COMET Vision software.
