Outdoor temperature | humidity | CO | NO2 sensor, PoM


Product description

Toxic gas sensor for harsh environments. It measures temperature, relative humidity, CO, NO2 and ambient light level. The supply voltage is 24 VDC PoM - this means that Modbus RTU communication and 24 VDC power supply can be connected via one RJ45 connector. The measured values are transmitted via Modbus RTU communication. This sensor can be installed outdoor or in harsh environments. The CO - NO2 sensor element is replaceable. All settings can be adjusted via Modbus RTU.

Additional specifications and description

 
Extract toxic gases
Combustion processes - for example cars moving around in an enclosed parking garage - release toxic gases like nitrogen dioxide (NO2) and carbon monoxide (CO). In order to maintain an adequate health and comfort level, the concentration of these toxic fumes must be monitored so that fresh air can be supplied in time. This HVAC sensor measures temperature, relative humidity, CO, NO2 and ambient light level. Based on the temperature and humidity measurement, the dew point is calculated. All these values are available via Modbus RTU communication.
 
Reduced installation time
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one UTP cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. To facilitate wiring, we recommend to use a Sentera 24 VDC power supply with RJ45 connector. These power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
 
Easy to use!
This sensor doesn't require any configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU. For example, the temperature or relative humidity range can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
 
High quality
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is solid and offers good protection against impacts. It offers an IP65 protection against ingress of dust and water. Each sensor is calibrated and tested in our factory. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. To ensure optimal performance, it should be protected from direct sunlight.
