In this episode of The Learning Circuit, you can learn more about the different types, how they use lenses to increase their range, and interesting technical details about PIR sensors. Hit play to watch another great lesson from Maker Karen and be sure to check out the followup video where Karen shows how to use a PIR sensor in a circuit by making a motion activated snow globe. </span></p><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: pyroelectric, radiation, infrared, e14presents_makerkaren, fresnel lens, detection area, passive, temperature, the learning circuit, motion sensor, movement, detection angle</div> https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5119/how-pir-motion-sensors-work----the-learning-circuit-81/revision/1Wed, 06 Oct 2021 22:29:01 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:fda60069-0b9b-4925-abc9-714b5f6b6d29tariq.ahmadhttps://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5119/how-pir-motion-sensors-work----the-learning-circuit-81#commentsRevision 1 posted to Documents by tariq.ahmad on 10/6/2021 10:29:01 PM<br /> <div style="background:#ffffff;padding:14px 16px 16px 18px;margin:0;vertical-align:top;border:1px solid #dadada;"><div style="float:left;display:inline-block;padding:0px 25px 8px 0px;"><a href="/challengesprojects/element14-presents/"><img alt="element14 presents" src="/e14/assets/legacy/2018/e14PresentsJune818.png" width="180px" /></a></div><div style="display:inline-block;vertical-align:top;width:70%;"><span style="font-size:18px;font-weight:bold;">How PIR Motion Sensors Work</span><p style="margin:0;"><span><a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/thelearningcircuit/">The Learning Circuit</a></span> <strong>|</strong> <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/">element14 presents</a> <strong>|</strong>&nbsp; <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/project-videos/">Project Videos</a></p></div></div><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"></p><span><a href="https://www.youtube.com/watch?v=jMnQmDgPCUg">www.youtube.com/watch</a></span><p style="margin:0;"></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;border:1px solid #b8d7e5;background-color:#e9f6fc;padding:8px;max-width:744px;"><span style="color:#000000;font-family:&#39;Open Sans&#39;, Arial, sans-serif;text-align:justify;">PIR or Passive Infrared sensors can detect movement by comparing variations in heat radiation of objects in their field of view.
