BT303

HeatMap 8×8

A proven 8×8 thermal-grid sensor for privacy-safe occupancy signals.

BT303 HeatMap 8×8

What this product improves.

BT303 was Blutech's first heatmap product. Its 8×8 thermal grid can indicate occupancy, approximate count, dwell, long-stay and no-motion with minimal privacy concern. It provides a lower-cost, lower-resolution option where BT337 or BT338 is not required.

Outcome for the property

Add dependable occupancy awareness to retrofit and smart-washroom projects.

Value for operations

Detect presence and approximate activity without the imagery associated with a camera.

How it fits the project

A practical retrofit sensor for individual cubicles and compact areas with ceilings no higher than 3 m.

Installation approach

Ceiling-mounted at up to 3 m. Wi-Fi supports live local 8×8 adjustment during setup.

Best suited to

  • Cubicle occupancy
  • Long-stay detection
  • Accessible toilet monitoring
  • Retrofit people counting

Built for a specific building outcome.

Each capability supports clearer information, faster response, better use of space or simpler operations.

01

Low-resolution thermal sensing

Detect presence and approximate activity without the imagery associated with a camera.

02

Local commissioning

Use Wi-Fi to view the 8×8 field and adjust the installation in real time.

03

Direct local response

Bluetooth can interact with nearby devices, such as triggering an indicator for a long-stay event.
