Ambient temperature | wall temperature | humidity sensor | PoM supply
This room transmitter is used to measure the temperature of the walls. It measures the ambient temperature, relative humidity, and light level in addition to the wall temperature. The dew point is calculated using the temperture and humidity measurements.
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. Modbus RTU communication is used to transmit the measured values.
The ambient light sensor can be used in many applications to control the ventilation system based on the occupancy of the room. Modbus RTU can be used to change all of the settings. The light intensity of the LEDs used for status indication can also be adjusted.

Why is it necessary to measure temperature and relative humidity?
This sensor not only measures the ambient temperature and relative humidity, but also the wall temperature. This information makes it possible to estimate the risk of condensation very accurately. 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. Excessive relative humidity causes condensation to form on windows, walls, and ceilings that are colder than the air temperature, potentially damaging building materials and causing odours in poorly ventilated spaces. By measuring the temperature of the wall, the risk of condensation formation can be calculated more accurately.
