Why is it necessary to measure temperature and relative humidity?
Temperature and relative humidity have a direct impact on residents' sense of well-being and comfort. Dry skin and itchy eyes are caused by dry air. Too high relative humidity levels will cause condensation to form on colder-than-air windows, walls, and ceilings, potentially damaging building materials and causing odors in poorly ventilated spaces.
How does it work?
This sensor measures temperature, relative humidity and ambient light level. Based on the temperature and humidity measurements, the dew point is calculated. The LED indicators provide a clear visual indication of the temperature. The green LED indicates that the temperature is within the acceptable range. The yellow LED illuminates when the temperature enters the alert range. Red denotes extreme heat or cold. The LEDs can also be used to display relative humidity. Modbus RTU provides access to the measured temperature, relative humidity, dew point, and ambient light level.
This sensor can be mounted on a wall or a surface indoors. The mounting holes are designed to accommodate standard European wall mounting boxes. Two screws are required to secure the sensor to the wall mounting box. The sensor enclosure will completely enclose the wall mounting box.
Reduced installation time
This sensor can be connected with just one RJ45 connector. Power over Modbus, or PoM, connects Modbus RTU communication and a 24 VDC power supply via a single cable. Modbus RTU communication makes all measured values available. To facilitate wiring, we recommend using Sentera 24 V DC power supplies with RJ45 connectors. These power supplies provide short-circuit, overload, and overvoltage protection. A supply voltage of 24 V DC improves the safety and reliability of your installation.
This sensor requires very little configuration. Once installed, it is almost directly ready to use. Temperature and relative humidity are frequently region- and season-specific. These parameters are still set to the correct values during installation. The other default settings are likely to be adequate for most applications. They can, however, be adjusted using the respective Modbus registers if necessary. The light intensity of the LEDs for status indication, for instance, is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
This HVAC transmitter is manufactured in Europe. 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. The enclosure offers an IP30 protection against ingress of dust and moisture. To ensure optimal performance, it should be protected from direct sunlight.
