HEART is a proactive personal occupational hygiene exposure monitoring system intended to record, store and analyze physiological and environmental data of each employee during his/her working shift.
- Recorded data are time and date stamped.
- Synchronised real time video recording which can estimate the location of the user when an event occurred
- Video and audio capability (when self initiated)
- Portable battery operated device fitted onto a harness
- Monitors the immediate working environment by periodic sampling for various parameters.
- Data is recorded onto a rugged non-volatile storage device
- Capacity of storing samples covering the entire working shift of at least eight to ten hours.
- Exposure warnings are displayed on a LCD screen on the sensor pack, with an audio alarm warning the user.
Central Management System (CMS)
- After each shift, all the data captured on the sensor pack and / or camera will be downloaded to a CMS database.
- The CMS will analyse the data and immediately flag any deviations or dangerous conditions

The heart rate monitor sensor is fitted onto a belt which the user wears around his/her chest. Data is communicated to the sensor pack through radio frequency wireless communication.
The body temperature sensor is used to measure the employee’s skin temperature. This sensor is housed in the same body belt as the heart rate sensor, which is worn around the user’s chest. Body temperature is measured from 30oC to 45oC with 1 decimal point precision. The sensor has a single zone of measurement.
Private Area Beacons
The Sensor pack has a Zigbee PRO compliant RF module built in. Video and audio in a private areas such as a bathroom or wash house are blanked out.
A mobile camera records all the video and audio for an eight hour shift. This is synchronized with the data on the sensor pack providing an audiovisual cue of where an overexposure has taken place. By default the audio recording is not presented due to privacy constraints.
