Product information "1-Wire Multisensor Air Quality Humidity and Temperature Sensor Pro II"

Elegant Multisensor for air quality, humidity and temperature Pro II for 1-Wire bus system without "Air quality traffic light", for professional applications, such as public institutions, authorities etc.

- High measuring accuracy for temperature, humidity (300 - 400% more accurate than standard 1-Wire sensors) and air quality
- low power consumption
- processing of the sensor values, therefore no complex formulas necessary -
- wall sensor (surface mounting)

With the multi-sensor for air quality (or called air quality), temperature and humidity, it is easy to monitor the indoor climate. It is one of the few sensors on the market that combines all three types of sensors in one attractive sensor housing. The air quality sensor used operates on the basis of a VOC mixed gas sensor.

With the help of the air quality sensor, a statement on the current air quality and advice on ventilation can be given. With the help of the humidity sensor, the humidity conditions in the room are monitored and a warning about possible mould growth could be issued via the evaluation software.

All sensors together make up an important sensor for heating and ventilation systems and are a main component of individual room control.
In combination with switch modules, e.g. actuators of radiators or ventilation systems can be controlled and regulated.

1-Wire components

DS2438 Multisensor for temperature, humidity and air quality


Temperature sensor with very high accuracy

Measuring range

- 40°C to +60°C (limited by the housing, sensor itself - 40°C to +125°C)


+/- 0.3° in the range of -10°C - 85°C


12 bit, 0.0625°C/bit

Air humidity

Sensor with high accuracy

Air humidity sensor

Capacitive sensor

Measuring range air humidity

0 -100% rel. air humidity


+/-3,5 %




12 bit, approx. 0.1% humidity

Air quality

VOC sensor with very high accuracy and low energy consumption

Air Quality Sensor Type

Mixed Gas Sensor (VCO Sensor)

Measuring range air quality

400 - 3500 ppm (CO2 equivalent)


+/- 5%, depending on the air composition

1-Wire connection

3 - wire connection (data, ground and 5V), parasitic operation not supported

Operating voltage

5 V= (+10%/-20%)

Power consumption

approx. 25mA


push-in terminal

Dimensions (outside)

80 x 80 x 32mm (LxWxH)

Note: Unfortunately, the Loxone 1-Wire Extension does not support the functional range of the module. Here we recommend the use of the 1-Wire Controller or the standard version of the 1-Wire Multisensor with the article number 11127, which we produce on request.
