Room temperature | humidity | TVOC sensor, PoM


Product description

Indoor air quality sensor to measure temperature, relative humidity, air quality and ambient light. 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. The TVOC sensor element is replaceable. In many applications, the ambient light sensor can be used to control the ventilation system in function of the occupancy of the room. All settings can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable.

How to measure indoor air quality?
TVOC or Total Volatile Organic Compounds evaporate from substances such as cleaning products, adhesives, paints, etc. TVOCs are also emitted from humans and animals. That is why a TVOC sensor provides a good, overall image of air quality. TVOC sensors are the best choice to control a ventilation system in residential environments.
  
Visual indication of the air quality
This HVAC transmitter offers a clear, visual indication of the TVOC level via the green, yellow and red LED. The green LED indicates that the TVOC level is within range - there is sufficient ventilation. When the TVOC level enters the alert range, the yellow LED lights up. Red means: TVOC out of range or insufficient ventilation. The measured temperature, relative humidity and TVOC level are available via the three analogue outputs and via Modbus RTU. Ambient light level is available via Modbus RTU.
 
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 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 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, parameters like temperature range, relative humidity range or TVOC 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
Each sensor is calibrated and tested in our factory. In the unlikely event of TVOC sensor element failure, this module can be replaced. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. The enclosure offers an IP30 protection against ingress of dust and moisture. It can be mounted on a wall indoors. To ensure optimal performance, it should be protected from direct sunlight.
