Beschrijving

Temperature, relative humidity, CO2 and ambient light are all measured by this room sensor. The CO2 level is visually indicated by the green, yellow and red LED lights. Modbus RTU communication is used to transmit the measured values. The CO2 sensor element is replaceable.

The power supply is 24 V DC PoM. This means that one RJ45 connector can connect Modbus RTU communication and a 24 V DC power supply. Ambient light detection is used in many applications to control the ventilation system based on the occupancy of the room. With Modbus RTU communication all settings can be adjusted. The light intensity of the LEDs used for status indication can also be adjusted.

This sensor is mostly used in buildings to monitor the CO2 level and to ensure that there is enough fresh air in the room. This CO2 sensor is often used in schools, office buildings and restaurants.

Is there sufficient fresh air supply?
People produce CO2 or carbon dioxide when breathing. Therefore, the CO2 concentration is a good indicator of the occupancy and activity level in a room. The higher the occupancy or activity level, the more fresh air is needed to maintain good indoor air quality. Therefore, CO2 sensors are used in many applications as an indicator of the ventilation requirement. In addition to CO2, this sensor also measures temperature, relative humidity and ambient light level. The measured temperature, relative humidity, CO2 level, dew point temperature and ambient light level are available via Modbus RTU communication.No analog outputs - only Modbus RTU communication
This sensor has no analog outputs, which makes it simpler and more cost-efficient. All measured values are available via the Modbus Input Registers of this sensor. Reading out the measured values is possible via SenteraWeb - our online HVAC platform, via 3SModbus software, via a BMS system or via another Modbus master device. Modbus has numerous advantages. The most important ones are that digital signals are less susceptible to interference than analog signals and that longer cables can be used. Cable lengths of up to 1,000 meters are possible.Visual indication of the measured value
This HVAC transmitter provides a clear, visual indication of the CO2 level via the green, yellow and red LEDs. The green LED indicates that the CO2 level is within range - there is sufficient fresh air supply. If the CO2 level enters the warning range, the yellow LED will light up. Red means that the CO2 level is too high or that there is insufficient fresh air supply. The ranges can be adjusted via the Modbus registers. The LED indicators can show the status of one of the three measured values, which is set to CO2 by default.Reduced installation time
One RJ45 connector is sufficient to connect this sensor. Modbus RTU communication and 24 V DC power supply are connected via one UTP cable - we call this Power over Modbus or PoM. All measured values are available via Modbus RTU communication. To simplify wiring, we recommend using the Sentera 24 V DC power supplies with RJ45 connector. These power supplies offer protection against short circuit, overload and overvoltage. A supply voltage of 24 V DC increases the safety and reliability of your installation.Surface Mounting
This sensor can be mounted indoors on a wall or surface . The mounting holes are designed for standard European wall mounting boxes. Two screws are required to attach the sensor to the wall mounting box. The sensor housing completely encloses the wall mounting box. Keep the sensor out of direct sunlight for optimal performance.Contemporary design housing
The housing is intended for indoor use only. It has an IP30 rating for protection against dust and moisture. Sentera Plastics designed and manufactured the housing themselves. It is extremely durable due to the use of high-quality r-ABS plastic. This sensor can be used in most interior styles thanks to its contemporary modern design.
