Temperature and Humidity Sensor | Wall mounting | 24 V DC
Product description
Room sensor for measuring temperature, relative humidity and ambient light. Intended for indoor wall mounting.
The supply voltage is 24 V DC, the measured values are communicated via three analogue outputs and Modbus RTU.
LED lights provide a clear visual indication of the temperature. Ambient light and dew point values are accessible through Modbus RTU.
Modbus RTU can be used to change all of the settings.
Additional specifications and description
Why do we measure temperature and relative humidity?
Temperature and relative humidity have a significant impact on human comfort and well-being. Dry air can lead to physical irritation and discomfort. Excessive relative humidity, on the other hand, results in condensation on windows, walls, and ceilings that are cooler than the air, potentially damaging building materials and causing unpleasant odours in poorly ventilated spaces.
Easy to install
Sensor intended for mounting on a wall or flat surface indoors. Mounting holes 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.
The supply voltage is 24 V DC, intended for 4-wire connection. As the ground terminals of the power supply (V-) and output (GND) are not connected internally, a 4-wire cable is required to connect this sensor. Cage clamp terminal blocks reduce wiring and installation time. They eliminate the need for routine maintenance and guarantee a reliable contact for solid or stranded wires.
Easy to use
Room sensor for measuring temperature, relative humidity and ambient light. Little configuration is required, the sensor can be used almost immediately once it has been installed. Temperature and relative humidity are frequently affected by region and season. These parameters are set to the correct values during installation.
The sensor has three analogue outputs. The three outputs have an overwrite function that can be activated via Modbus RTU. Output type is set to 0-10 V by default, but different output types are available, including 0-10 VDC, 0-20 mA, 0-100% PWM, or Modbus RTU. One of the measured values (temperature / humidity) is transmitted by each of them. For instance, output 1's default setting will transmit 0 V at 0 °C and 10 V at 50 °C. In proportion to the measured temperature and / or relative humidity, each output value changes.
A clear, visual indication of the temperature is offered via the green, yellow and red LED. The green LED shows that the temperature lies within range. The yellow LED turns on when the temperature enters the alert range. The red LED indicates extreme heat or cold. The LEDs can also be used to display relative humidity. The analogue outputs and Modbus RTU both provide access to the measured temperature and relative humidity. Dew point is calculated using the measured values and is accessible through Modbus RTU. Ambient light sensor can be used in applications to control the ventilation system based on the occupancy of the room. The ambient light level is accessible through Modbus RTU. Light intensity of the LEDs used for status indication can be adjusted.
