Mouser now stocks the ams OSRAM AS7343L 13-channel multi-spectral sensor. This compact sensor joins multi-channel colour analysis with XYZ sensor technology to match the human eye’s perception of colour and light intensity. When combined into colourimeters, portable spectrometers, and consumer devices, the sensor provides users with added productivity, flexibility, and functionality in applications for lighting control, colour matching, and spectral analysis. The device is optimised for transmissive, reflective, and emissive measurements, incorporating lateral flow test applications, colour matching, fluid or reagent analysis, and spectral identification in the visible range.

The multi-purpose sensor is ideal for colour analysis in applications requiring regular, accurate measurements. In agriculture, operators of greenhouses and indoor farms employ colour analysis to optimise the spectral characteristics of horticultural lighting and to maximise yield and energy efficiency. Various parts of the visible light spectrum stimulate different crops’ growth.

Another application for the device is in smoke alarms and heat alarms to detect spectral smoke signatures. Spectral analysis by the sensor can provide a smoke sensor to distinguish between different types of smoke, from burning wood to plastic or water vapour.

The device is housed in a flat 3.1mm x 2mm x 1mm package, ideal for space-constrained applications. The device combines a programmable digital GPIO and LED driver, facilitating light source and trigger/sync control. Device control and spectral data access are implemented via a serial I²C interface.
