Multi-spectral sensor fits into tight spaces

This compact sensor combines multi-channel colour analysis with XYZ sensor technology to match the human eye’s perception of colour and light intensity.

When integrated into colourimeters, portable spectrometers, and consumer devices, the AS7343L gives added productivity, flexibility, and functionality to users in applications for colour matching, lighting control, and spectral analysis.

The device is optimised for reflective, transmissive, and emissive measurements, including lateral flow test applications, fluid or reagent analysis, colour matching, and spectral identification in the visible range.

The sensor is ideal for colour analysis in applications which require frequent, accurate measurements.

In agriculture, operators of greenhouses and indoor farms use colour analysis to optimise the spectral characteristics of horticultural lighting and to maximise yield and energy efficiency. Different crops’ growth is stimulated by different parts of the visible light spectrum.

Another application for the AS7343L is in smoke alarms and heat alarms for the detection of spectral smoke signatures.

Spectral analysis by the sensor can enable a smoke sensor to distinguish between different types of smoke, from burning wood to plastic or water vapour.

The AS7343L is housed in a flat 3.1 mm x 2.0 mm x 1.0 mm package, ideal for space-constrained applications.

The device integrates a programmable digital GPIO and LED driver, facilitating light source and trigger/sync control.

Device control and spectral data access are implemented through a serial I²C interface.
