1 Introduction
Before you start installing the living area sensor in order to put the device into operation, please read these
operating instructions carefully to the end, especially the section of the safety instructions.
2 Product description
With the Multisensor a simple monitoring and recording of the indoor climate is possible.
For heating systems (individual room control) and ventilation systems it is an important sensor to achieve a good
and stable control of temperature/ humidity.
The Multisensor is also optimal to warn of possible mould growth.
A calibration of the internal sensors is not necessary. The unit can be put into operation immediately without
waiting time. The Multisensor contains a 1-Wire module of type DS2438, to detect temperature, humidity,
brightness and operating voltage. The integrated humidity sensor has a high accuracy in the range of 10 - 85%
relative humidity.
A brightness sensor is used to measure twilight and brightness values within living spaces. The sensor can be
used, for example, to control roller shutters or venetian blinds on the basis of brightness. Constant lighting control
of living and working areas is also possible.
A special photodiode with a human-like detection light spectrum is used.
The 1-Wire Multisensor is designed to detect relative humidity, temperature, brightness and its own operating
voltage. The 1-Wire Multisensor has an individual 1-Wire serial number.
The sensor is intended for use in living areas.

For rooms with permanently high air humidity values, such as saunas, we recommend the
1-Wire outdoor Temperature-Humidity Sensor (Art.No: 11135).
The living area Sensor is integrated into a 1-Wire Network via screwless pressure clamps or RJ45 plug
connection (CAT cable).
The living area Sensor is designed for cable entry from the rear or side. The housing cut-outs must be adapted to
the cable entry.

https://www.esera.de/service-support/kompatible-steuerungen-zentralen/fhem-integration/
11 Manual calculation of sensor values
The following formula can be used to evaluate the humidity sensor.
VDD = operating voltage (5V), VAD = humidity sensor, analog value of DS2438, Xsense = light sensor, analog
value of DS2438.
Humidity calculation
Offset = 0.847847 (Zero Offset V), slope = 29.404604 (Slope: mV/ %RH)
Srh = (VAD_new - offset) / (slope / 1000)
rFH = (Srh + 2)/ ((1.0305 + (0.000044 * temperature) - (0.0000011 * temperature x 10²)))
For Loxone control:
I1 = VAD-value, I3 = Temperature
((((5/I2*I1)-0,847847)/(29,404604/1000))+2)/((1,0305+(0,000044*I3)-(0,0000011*I3^2)))
Brightness calculation
Xsense in Volt, Factor = 25600
Correction for operating voltage fluctuations: Xsense = (5 / VDD) * Xsense
Brightness (LUX) = (0,223V - Xsense) * Factor
Note on brightness measurement:
It should be noted that the placement of light sources in relation to the angle of incidence of the Multisensor may
cause considerable deviations in the brightness readings of hand-held brightness meters.
Brightness control:
In the case of illumination with fluorescent or LED lamps, the value may additionally fluctuate. A living room
brightness control is usually impaired by strongly changing lighting conditions, e.g. shadows cast by people in the
room and the resulting fluctuations in sensor light values, and a well-functioning control function is often difficult to
implement. This is largely due to the unfavourable positioning in the light switch area for measuring the brightness
of the Multisensor.

12 Pin assignment
The temperature and humidity sensor is connected via push-in terminals (screwless terminal) or RJ45 modular
socket. The connection terminal is intended for solid cables with a cross section of 0.2 to 2.5 sq. mm or fine
stranded cables with a cross section of 0.2 to 1.5 sq. mm.
The terminal assignment of the screw terminals is printed on the printed circuit board. The correct polarity must
be observed when connecting.
The Multisensor must be supplied with three cables (ground, 1-Wire Data and 5V). The parasitic mode is not
supported.
Pin assignment RJ45 socket
1 = GND 5= GND
2 = +5V 6 = not connected
3 = GND 7 = not connected
4 = 1-Wire 8 = GND
1-Wire primary and 1-Wire secondary
not connected
Note: Basics and tips for the 1-Wire bus system can be found on the ESERA website at
https://www.esera.de/service-support/1-wire-grundlagen/
13 1-Wire Network Cabling
For short connection lengths, no special requirements are placed on the cable used. With unshielded cable,
e.g. telephone cable J-Y(St)Y telephone line 4x2x0.8, 1-wire networks can be set up in star or tree wiring of
approx. 30 - 80m. We recommend the use of CAT 5-7 network cable for installation. For cable assignment
you will find a recommendation in the article download.
Shielded cable, e.g. CAT5 or CAT6 cable should be used in the Smart Home, in commercial buildings and in
industrial environments. This ensures a very good system stability of the entire system. Another advantage
of cabling with CAT cable is that a linear bus topology can be achieved despite star-shaped cable routing in
buildings. This is only possible due to the 8-wire cable structure of the CAT cable.
When using CAT7 cable, the maximum possible cable length of the entire 1-wire network is reduced due to
the stronger shielding and the resulting higher cable capacity.
With star or tree cabling with CAT cable, a total length of approx. 50-100m can be calculated, which
corresponds to 1-2 floors in a residential building.
In general, unnecessary cable connections, branches or cable extensions should be avoided. Each joint or
clamp connection reduces the maximum available network size.
The special feature of wiring multi-sensors with 1-Wire BUS technology is that all sensors are operated via a
three-wire cable. Both power supply and data communication take place via the bus line.
14 Operating conditions
The module may only be operated at the specified voltages and ambient conditions. The device can be
operated in any position. The device is intended for use in dry and dust-free rooms.
If condensation is formed, wait at least 2 hours for the unit to acclimatize.
Do not operate the module in an environment in which flammable gases, vapors or dusts are present or may
be present.
15 Assembly
The Multisensor should be mounted upright with the ventilation openings at the top and bottom. It is intended for
temperature and humidity measurement of air and gases in indoor areas, such as living rooms, offices,
workshops or public facilities. The measured values specified under technical data are limit data for the entire 1-
Wire Multisensor and must not be exceeded or fallen short of, as the Multisensor may otherwise be damaged.
