Text for tenders: Wireless humidity sensor


Wireless humidity sensor

The wireless humidity sensor is used for monitoring

relative humidity levels. It may be operated

with the wireless I/O unit. Every 120 seconds, a

measurement is sent to the central wireless base

system. The humidity sensor is accommodated

behind a protective membrane and contains a

long-life 3.6 V lithium primary cell which may be

replaced if necessary. It is mounted using the

mounting bracket enclosed with the supply which

may be secured e.g. to the enclosure frame.

The sensor is simply mounted on the bracket.

If a higher IP protection category is required, the

sensor may be retrofitted with the IP protective

cover.

The battery and the radio connection quality of

the sensor are monitored.
