摘要
本文介绍一种被动红外感应式水龙头,利用人体产生的红外辐射作为信号源,选用红外光子型探测器掺杂锗来探测,可以高效响应人体辐射的峰值波长,并且响应快,受环境温度影响小。在详细分析人体辐射特性的基础上,选择合适的红外探测器和相应的信号处理电路,设计了被动式红外感应自动水龙头系统,用指示灯代替水龙头,并验证了设计方案的正确性。
The article introduces a kind of passive infrared induction faucet, that is infrared radiation generated by the human body as a signal source, chooses the infrared photon detector doping germanium to detect, which can efficient response to the peak wavelength of radiation human body, and response rapidly, free from interference environmental temperature. On the basis of detailed analysis of the human body radiation characteristics and selecting the appropriate infrared detector, the design of passive infrared induction automatic faucet was built, with the corresponding signal processing circuit, using indicator light instead of faucet, validated the correctness of design scheme.
