Software / control
The 1-Wire Multisensor Pro II is read out via 1-Wire command for DS2438 devices. The Multisensor is
supported in many controllers, such as ESERA-Station, Loxone, IP-Symcon, OWFS, FHEM, (Linux) or
microcontroller applications.
For ESERA 1-Wire Multisensor of the Pro Series no complex formulas are necessary anymore.
A sensor controller within the Multisensor takes over the preprocessing of all measured values and thus
simplifies the integration into 1-Wire systems enormously. Complex formulas are no longer necessary.
Also, the measured values are no longer dependent on the operating voltage of the 1-Wire Multisensor.
The sensor measurement values are assigned to the standard DS2438 device values (according to the data
sheet) as follows:
VDD = operating voltage (5V), VAD = humidity, Xsens = air quality.
Calculations:
Temperature:
Standard output according to DS2438 module
Operating voltage:
Standard output according to DS2438 module
Air Humidity:
To obtain the rel. humidity in percent, multiply the output value (Vas) by a factor of 10.
0.1V corresponds to 1% relative humidity
Air quality:
The air quality is output in accordance (equivalent) to CO2 sensors.
After start-up, the sensor outputs 0V for a few minutes. This means that the air quality sensor is in the start-
up phase.

400 - 1800 ppm (CO2 equivalent)
+/- 10%, depending on air composition
30-250mV corresponds to 400-2900ppm, 1mV output voltage
corresponds to 11,6ppm. Smallest output value: 30,51mV
corresponds to 405ppm.
