Detector Reference Design
The hardware (EVAL-CN0537-ARDZ) is for prototyping and solution evaluation.
A tested and verified UL 217 smoke detection algorithm is
embedded as part of the installer for evaluation.
The data (EVAL-CN0537-DATA) package provides an extensive number (1000+) of
smoke datasets taken at UL 217 certified facilities for those who wish to
develop their own algorithm.
It includes the CN-0537 source code for initialization,
calibration, environmental compensation, and data preprocessing—but excludes
the detection algorithm.
The algorithm (EVAL-CN0537-ALGO) package includes everything in the data
package and adds a UL certified smoke detection algorithm and associated
algorithm project files.
Module for Smoke Detection
Supports UL 217 8th edition/UL 268 7th edition, EN 54; GB; ISO
• Lowers nuisance alarms using dual wavelength detection with
higher SNR and dynamic range
On-chip calibration reduces end of line calibration requirements
Ultra low power (25 μW average in a four pulse configuration) dissipation
enables smaller/cheaper batteries
Space-saving integrated module (3.8 mm × 5 mm × 0.9 mm) with one blue LED, one
IR LED, two photodiodes, and an AFE
• Enables more industrial design options
• Simplifies EMC design
