WiFi temperature and relative humidity sensor with integrated probe Comet W3710

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, SNMP, 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, SNMP protocol or by sending JSON data to an http server. Sensor allow to provide 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.

INCLUDED IN DELIVERY:

• Sensor W3710
• Instruction Manual
• Traceable Calibration Certificate
• Temperature and relative humidity probe
• Power Supply
• USB-C Cable
• COMET Cloud for 3 Months (given by manufacturer)
• Warranty: 3 years

Key features:

• Measurement from external sensor temperature and relative humidity. From relative humidity values are calculated additional humidity quantities like a dew point.
• Monitoring and alarming of the measured values to the pre-set limits. Two alarm limits are supported for each measured quantity with selectable direction.
• Acoustics and optical LED signalisation of the alarms.
• Measured values are shown on a large LCD display with backlight.
• Holding of minimum and maximum values from device start-up for each measured quantity. Minimum and maximum values can be reset by the end-user manually.
• Communication via 2.4 GHz WiFi network. Device can be used with wireless infrastructure which is already available at place of installation.
• Device is equipped by the USB-C connector which is used for powering of the device. Same connector can be used for device configuration if needed.
• Measured values can be shown on device web pages and can be transferred into data acquisition system COMET Cloud or COMET Database.
• 3rd party data acquisition systems are supported via JSON, XML, Modbus TCP and SNMP protocols.
• Device has integrated internal non-volatile memory. Memory is used for recording measured values in case WiFi or internet connection outage.
• Occurrence of alarm states can be reported by the email sent from the device.
• Device configuration via web pages from computer or cell phone. Initial device provisioning is done via access point mode.
• The device delivery includes traceable calibration certificate. Declaration of metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
