Product description
With the MS 100 1-Wire Multisensor you have purchased a professional Multisensor.
Due to the most modern sensor elements, the accuracy of the MS 100 Multisensor of the rel. humidity
measured values is on average 50% - 100% higher, compared to most sensors on the market.
A Brightness sensor is used to measure the twilight and brightness values within living spaces. A special
photodiode with a human-like detection light spectrum is used.
The MS 100 is installed in a shapely surface-mounted housing and fits harmoniously into modern
furnished living and business rooms.
Thanks to the generous ventilation openings, the 1-Wire Multisensor detects the climate conditions in
rooms very directly and quickly. For all types of radiator and heating controls, an accurate Temperature
sensor such as the one installed in the Multisensor is an important component.
In combination with 1-Wire ESERA Switching modules / binary outputs, a very effective and energy-
saving heating control (single room control) is possible.
The Multisensor is also optimal to warn of possible mold formation.
The MS 100 Multisensor is intended for use in normal living spaces. For outdoor use and in damp rooms,
such as sauna or steam bath, a suitable sensor is available from the ESERA website.
Calibration of the internal sensors is not necessary. The device can be put into operation immediately
without waiting time. The electrical connection to the 1-Wire Bus system of the MS 100 is done with screw
terminals and can be operated in standard mode with 3 cables for ground, data and 5V.
Each MS 100 Multisensor has an individual serial number.
The Multisensor contains an original 1-Wire chip of the type DS2438..
