摘要

火焰传感和早期火灾探测是现代安防监控系统的主要特征。光学检测系统得到了广泛的发展，并提供了最高的灵敏度和选择性，但它们仍然昂贵，并且显示出高功率预算。本文提出了一种基于PbS胶体量子点的低成本、低功耗火焰探测器。我们展示了检测器的工作，总功耗为21 nW，能够以5 dB的信噪比(SNR)检测20米处蜡烛的火焰。

High Sensitivity Flame Sensor Based on PbS Colloidal Quantum Dots

Flame sensing and early fire detection are primary features in modern security and surveillance systems. Optical detection systems are widely developed and offer the highest sensitivity and selectivity but they are still expensive and show a high power budget. Here we propose a low-cost, low-power flame detector based on PbS colloidal quantum dots. We show detector operation with a 21 nW total power dissipation and the ability to detect the flame of a candle at 20 m with a 5 dB signal to noise ratio (SNR).
