Does the Modbus humidity sensor include a temperature sensor?
Humidity is generally invisible to the human eye and it is a concentration of water vapor, which is a gaseous state of water, present in the air. The humidity is always in cooperation with temperature. Modbus humidity sensor (RS485 humidity sensor) therefore always measures temperature as well as humidity. The humidity can not be measured without the temperature and vice-versa. We know how to measure the absolute humidity, relative humidity, and specific humidity.
Below we will try to give you the ideas of optimal room temperature and humidity as well as the guide for correct mounting of those sensitive sensors.
1. Optimal humidity in different rooms with Modbus humidity sensor
The most important humidity for us is relative humidity, especially if we talk about the indoor living spaces. The ideal humidity for our homes is between 40-60% with temperatures from 18-22 °C. Those optimal living conditions can be achieved and monitor with Andivi’s Modbus humidity sensor ANDRFFT/R-MD/S.
After several years of experience in building management systems, we have found out that people do not like to have the same temperature and humidity in every room. Sleeping rooms tend to be a lot cooler with higher humidity than for example living room. We would present to you our findings below:
People often ask us how can we achieve the perfect living conditions? Well, it’s all about optimization. If we use the Modbus or RS485 humidity sensor which is connected to controller U-DDC then we can achieve the perfect room automation, including temperature and humidity. We would therefore like to ask you what are your perfect living temperature and humidity conditions?
2. Where to mount the humidity detector?
Building automation means nothing without reliable and well-placed sensors. Why? Because sensors with its measurements control the whole system. That means that for example temperature sensor is placed very close to a window or near the air condition or heating system, the measurements will not be correct at all.
The Modbus humidity sensor has to be placed somewhere neutral. We like to mount it somewhere hidden. But on the other hand, the RS485 humidity sensor is not so sensitive and can be mount almost everywhere inside the room. The most sensitive sensors are air quality sensors that have to be mounted around 1,4m height and away from windows and doors because airflow change can change its measurements drastically.
We prefer to mount the Modbus humidity sensor behind the open shelf where it can be hidden by other objects, but on the other hand still measure the correct air humidity and temperature.
3. The best indoor and outdoor humidity sensor (Modbus version)
Andivi’s indoor or outdoor Modbus humidity sensor is made for measuring the relative humidity and temperature in living and office spaces, reception halls, foyers, etc. The measuring transducer records the temperature and humidity via an internal sensor and converts the value into a standardized analog output signal in the range between 0-10V/4-20 mA.
Additional options for the sensors can also be a passive potentiometer, active potentiometer, relay, or Modbus connectivity.
The housing has IP20 protection which is more than enough for indoor use. We can also offer you an outdoor version with IP65 protection that means that it is protected from total dust ingress and low-pressure water jets from any direction.
