Introduction
The HACS1 Ambient Sensor is designed to be installed in residential, commercial, and industrial facilities to
monitor ambient temperature, humidity, lighting level, and substrate moisture content (such as sheetrock,
wood, etc.). The information is used to detect a range of dangerous conditions including high relative
humidity conducive to indoor mold growth, occult moisture accumulation behind walls and ceilings and
plumbing leaks.
The sensor is also useful for occupancy and activity detection in bathrooms and near exterior doors,
detecting rapid changes in temperature, humidity and lighting levels. For example, data from the HACS1
could be used to indicate the shower is being used (the lights are on, and the relative humidity is suddenly
rising). If the leak detector on the floor goes into alarm because water from the shower curtain is leaking
onto the floor, this false alarm condition can be detected and avoided.
Further, because condominiums, apartments and other MDUs typically use identical floor plans in each stack,
installing an HACS1 over the toilet and near the shower also places it directly beneath the shower and toilet
of the apartment above, enabling it to detect and warn of occult moisture problems in the ceiling from
plumbing problems from above.
The HACS1 is designed to be used with a compatible Halo System 319.5MHz receiver. Enrollment is
accomplished via the web portal, and is detailed in other documentation covering usage of the web portal.
Installation guide
The HACS1 should be installed in locations where occult moisture may accumulate behind walls and ceilings,
and in locations where occupancy detection is needed. Primarily in the bathrooms, near exterior doors, and
other places where occupancy or occult moisture should be detected.
