Halaman Cetak

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
