ماژول PIR (تشخیص حرکت) مدل SR602

به طور کلی اجسام به نسبت حرارتی که دارند از خود نور مادون قرمز (IR یا Infrared) ساطع می کنند . این موضوع در بدن جانداران نیز وجود دارد . سنسور های PIR با اندازه گیری IR محیط و تشخیص تغییر آن حضور و حرکت موجودات زنده را تشخیص می دهند . از این سنسور ها در لامپ های هوشمند ، سیستم های امنیتی و… استفاده می شود .

زاویه دید 100 درجه

حداکثر فاصله قابل تشخیص 4 متر

Introduction

This is Micro SR602 Human Body Sensing Module Pyroelectric Infrared Sensor. After the high level of the sense output, during the delay time period, if the human body is active in its sensing range, its output will remain high until the person leaves, and the delay will be high. It becomes low level (the sensing module automatically delays a delay period after each activity of the human body is detected, and the time of the last activity is the starting point of the delay time).
SR-602 Pyroelectric Human Infrared Sensor Module is a PIR based Infrared motion sensor. SR-602 Pyroelectric human body infrared sensor module has Sensing distance up to 4 meters but the best performance is 0-3.5Meters. Its Output is high level, H=3.3V, L=0V, and power supply is DC: 3.3V-15V, Quiescent current is 20uA. This SR602 module has high sensitivity, fast response, small static power consumption, small size, easy to install.
The high-level time of the output of this product is adjustable, 1.8 seconds to 1 hour. The output time set at the factory is 1.8 seconds.
