Valor Chamberless Smoke Detection
 

Valor Chamberless smoke detection uses multispectral light scattering to scan into the open room for smoke. Infrared light (invisible to the human eye) checks for the presence of airborne particles and visible light confirms whether the particles are smoke. Because smoke reflects infrared and visible light differently than nuisances like steam, dust, or cooking aerosols, Valor Chamberless only alarms when smoke is present.

Valor Chamberless works under any ambient light condition and has power consumption and manufacturing cost equivalent to a traditional photoelectric smoke detector.

To put Valor Chamberless into a product, only two components are required:

  1. Photometric module Valor Chamberless is optimized to work with the Analog Devices ADPD188BI photometric module, which integrates infrared and visible light emitters, photodiodes, and signal processing circuitry into a single surface mount component. The ADPD188BI comes factory calibrated—no additional calibration is required by the manufacturer—and is mounted using automated pick-and-place equipment.

  2. Microcontroller (MCU) Valor Chamberless can efficiently run on an MCU with a minimum of an 8-bit core, 8 kB of program memory, and 1 kB of RAM. The source code containing the Valor Chamberless algorithm is written in C/C++ and gets programmed into the MCU firmware.

Valor Chamberless is developed for standalone smoke detectors but can be easily integrated into any platform, from building sensors and appliances to handheld devices and wearables. Find out how to put Valor Chamberless into your products.
