Calculations
Temperature
Standard output according to DS2438 module
Operating voltage
Standard output according to DS2438 module
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
Air quality is output on the basis of (equivalent) CO2 sensors.
After starting the sensor the first time, it will output 0V for a few minutes. This means that the air quality
sensor has switched in start up mode.
In normal operation, the minimum output value is 30.5mV, which equals 405 ppm equivalent CO2.
An increase of the output voltage is in the ratio 1mV per 11.6ppm CO2.
As an example, an output voltage of 60.2mV corresponds to 698.3ppm CO2.

Data output 1-Wire Controller / 1-Wire Gateway
For the 1-Wire Multisensor Pro I, the following measured values are output by the 1-Wire Controller / 1-Wire
Gateway.
Data output:
1_EVT|12:27:40
1_OWD1_1|2008 => controller no._module no._data record | temperature (°C) example: 20,08 °C
1_OWD1_2|511 => controller no._module no._data record |voltage VCC (V)
1_OWD1_3|850 => controller no._module no._data record |rel. humidity (rF) example 85,0%
1_OWD1_4|1200 => controller no._module no._data record |dew point (°C) example: 12,00 °C
1_OWD1_4|80000 => controller no._module no._data record |air quality (ppm CO2) example: 800,00 ppm

Integration in IP-Symcon / ESERA-Station
Through our website we provide ESERA IP-Symcon software-modules to import the 1-Wire Multisensor in
IP-Symcon via 1-Wire Controller / 1-Wire Gateway. Therefore, no scripts are necessary.
Further details can be found here:

For a conventional connection by a 1-wire bus coupler, the sensor values are to be calculated according to
the given formulas.
14
Integration in Loxone
At our webshop we provide a sample project on how to import the 1-wire Multisensor by 1-Wire Controller
1/1-Wire Gateway.
