Thanks to the generous ventilation openings, the 1-Wire Multisensor Pro I very directly detects the ambient
conditions in rooms.
The 1-Wire Multisensor Pro I has a warm-up time for the air quality value. With a new 1-Wire Multisensor,
this warm-up time is approx. 15 hours. After initial start-up, this is reduced to minutes or hours, depending on
how long the Multisensor was without power. The warm-up phase is indicated by the red LED flashing.
During the warm-up period, the air quality is output with the value 0. For further details, see chapter
“commissioning and warm-up”.
The 1-Wire Multisensor Pro I is equipped with screw terminals for the electrical connection of the 1-Wire bus
interface and can be operated in standard mode (3 cables for ground, data and 5V).
Due to the use of high-quality internal sensors with 12-bit resolution, the 1-Wire Multisensor Pro II delivers
very accurate values for temperature, relative humidity and air quality. In addition, the evaluation of the
delivered measured values is enormously simplified.

Auto-E-Connect® Support
The ESERA
Auto-E-Connect®
1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid 2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3,
or in the download area for this article in the ESERA Webshop
