Product description

This sensor controller regulates the humidity and temperature in a room using Modbus RTU. It gauges the temperature, relative humidity, and ambient light intensity. The dew point is determined using the measured values for temperature and humidity. The supply voltage is 24 V DC PoM, which enables Modbus RTU communication and 24 V DC power supply to be connected via a single RJ45 connector.

By using Modbus RTU communication, the sensor algorithm can directly control an EC fan, an AC fan speed controller, or a damper actuator. Modbus RTU is used to access all measurements and the output value and allows for the adjustment of all settings. The LEDs used for status indication also have adjustable light levels. The ambient light sensor can be used in many applications to regulate the ventilation system based on how many people are in the room.

Additional specifications and description

Are the values for the temperature and humidity okay?
The green, yellow, and red LEDs on this HVAC sensor controller provide a distinct, visual indication of the temperature. The green LED shows that the temperature is within acceptable limits. The yellow LED turns on when the temperature reaches the alert range. Red indicates extreme temperatures. The LEDs can also be used to visualise relative humidity. Modbus RTU provides access to the measured temperature, relative humidity, and ambient light level. This sensor's output can operate a damper actuator, an AC fan speed controller, or an EC fan. In proportion to the measured temperature and relative humidity, the output value changes. For instance, the sensor will increase the fan speed or open the damper if the relative humidity rises.
Save time during installation
It only takes one RJ45 connector to connect this sensor. Power over Modbus (PoM) refers to the connection of Modbus RTU communication and a 24 V DC power supply via one single cable. We recommend using a Sentera 24 V DC power supply with RJ45 connector to make wiring easier. These power supplies have short-circuit, overload, and overvoltage protection. A supply voltage of 24 V DC improves the safety and dependability of your installation.
Easy to use
This sensor requires very little configuration. Once installed, it is almost directly ready to use. Temperature and relative humidity are frequently region- and season-dependent. 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.Temperature controller Modbus RTU
High quality
This HVAC sensor controller 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. It can be mounted on a wall indoors. To ensure optimal performance, it should be protected from direct sunlight.
