They are small, inexpensive, low-power, easy to use and don&#8217;t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. PIR Motion sensor are often referred to as PIR, &#8220;Passive Infrared&#8221;, &#8220;Pyroelectric&#8221;, or &#8220;IR motion&#8221; sensors.<\/p>\n<p>PIR sensors are basically made of a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Pyroelectric\">pyroelectric sensor<\/a> , which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. <a href=\"https:\/\/www.proftech.co.ke\/?s=PIR+Motion+sensor&amp;post_type=product\">motion<\/a> detector is actually split in two halves. The reason for that is that we are looking to detect motion (change) not average IR levels. The two halves are wired up so that they cancel each other out. If one half sees more or less IR radiation than the other, the output will swing high or low.<\/p>\n<h2><span class=\"st\">PIR Sensor<\/span> Features;<\/h2>\n<ul>\n<li><span class=\"a-list-item\"> Detect motion up to 7 meters away <\/span><\/li>\n<li><span class=\"a-list-item\"> Perfect for Raspberry Pi or Arduino Projects <\/span><\/li>\n<li><span class=\"a-list-item\"> Easy to use <\/span><\/li>\n<li><span class=\"a-list-item\"> Requires soldering of header pins <\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>PIR Motion sensor Proftech PIR Motion sensor allow you to sense motion, almost always used to detect whether a human&#8230;<\/p>\n","protected":false},"featured_media":4919,"template":"","meta":[],"product_brand":[],"product_cat":[74],"product_tag":[],"class_list":["post-4873","product","type-product","status-publish","has-post-thumbnail","product_cat-intruder-and-burglar-alarm-systems","first","instock","sale","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
