Temperature | humidity controller wall mounting | PoM
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
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.
