The Halo IoT Sensor can provide detections and alerts on a variety of environmental factors, such as air quality, light changes, temperature and humidity, and others. All of these events can be used to configure Rules within Arcules to either notify or raise alarms.

Your integrator may not have configured all of these event presets for you at the time of your install, but can be configured at any time.

Halo Sensors trigger an Aggression event if it determines a threshold above normal volume is registered.

Halo Sensors can detect gunshots indoors, within a 360 degree 25 foot radius of the sensor itself.

Halo Sensors can detect via audio analysis someone using specific keywords to trigger a Help Event

Halo Sensors detect the ambient temperature of the room. The Temperature Event triggers if the temperature in the room rises above the threshold temperature.

Halo Sensors detect the ambient temperature of the room. The Temperature (Low) Event triggers if the temperature in the room dives below the threshold temperature.

Halo sensors will detect the relative humidity for the room in which they are installed. A Humidity Event will be triggered if the relative humidity in the room rises above the threshold percent.

Halo sensors will detect the relative humidity for the room in which they are installed. A Humidity (Low) Event will be triggered if the relative humidity in the room dives below the threshold percent.

Halo Sensors will detect the Barometric Pressure within the room. A Pressure Event will be raised if the pressure of the room proceeds over the configured value.

Halo Sensors will monitor the light level (in Lux) within the room. a Light (Lux) Event will be triggered if the light level increases above the configured value.

Halo Sensors have the capability to detect the barometric pressure in Hg. You can set thresholds of if the pressure exceeds a certain amount, or if it falls below a certain measurement.

Halo Sensors can detect high concentrations of Carbon Monoxide in the air, preventing overexposure to the colorless, colorless gas.

Halo Sensors have two measurements for Carbon Dioxide. The CO2cal is a direct calculation of CO2 in the air, while the CO2eq is an indirect measurement by basing levels off of other environmental gasses. The threshold can be adjusted by using the CO2eq event.

Halo Sensors can detect if there are high amounts of Nitrogen Dioxide in the air. NO2 emissions are primarily emissions from vehicle exhaust gases, & domestic heating.

Halo Sensors can detect if there is an overage of ammonia fumes in the air, triggered by the NH3 sensor in the unit.

Halo Sensors can detect various organic compounds that can have shot or long term effects. TVOC events can be triggered by the threshold on the TVOC sensor.

The Halo Sensor's events for Air Quality Index is a combination of the following readings:

This is a rolling average of the results of these sensors to create an aggregate rating.

All of these sensors are derived by the Particulate Matter (10 micron) sensor. Different concentrations and chemicals trigger this sensor to differentiate between the 3 events.

Halo Sensors define Smoking as 200 parts per million of 10 micron particles by default.

Halo Sensors define Vape as 35 parts per million of 10 micron particles, without THC, by default, with the addition of a dynamic learning algorythm.

Halo Sensors define THC as 35 parts per million of 10 micron particles, with the added presence of THC in the air sample.

Halo Sensors define Masking as 35 parts per million of 10 micron particles, but with the embedded algorithm, know that this is aerosol or cologne versus a vape device.

Halo Sensors have a built in thermal detection algorithm to determine what signature consists of a human and performs people counting based on this.
