This compact yet powerful module consists of an array optical sensor with a lens and a built-in convolutional neural network inference core. mVMR1108 module is also equipped with two infrared or white LED beads that act as flash lights. As shown in the figure below, by default, the LED beads are located at LED1 and LED2. They can also be moved to the vacant pads labelled LED3 and LED4.<br \/>\nThe mVMR1108 can read data at short focal lengths (as little as 2 cm) and is equipped with a large field of view lens suitable for reading all types of meters.<\/p>","protected":false},"featured_media":1145,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_cat":[40],"product_tag":[],"featured_image_urls":{"full":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",800,800,false],"thumbnail":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",150,150,false],"medium":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",300,300,false],"medium_large":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",768,768,false],"large":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",800,800,false],"1536x1536":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",800,800,false],"2048x2048":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",800,800,false],"trp-custom-language-flag":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",12,12,false],"woocommerce_thumbnail":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",500,500,false],"woocommerce_single":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",600,600,false],"woocommerce_gallery_thumbnail":["https:\/\/vegesense.net\/wp-content\/uploads\/2024\/07\/01.jpg",100,100,false]},"post_excerpt_stackable":"<p>mVMR1108\u662f\u4e00\u6b3e\u667a\u80fd\u9635\u5217\u5149\u5b66\u4f20\u611f\u5668\uff0c\u5177\u5907\u8fb9\u7f18\u4eba\u5de5\u667a\u80fd\u8ba1\u7b97\u80fd\u529b\u3002\u8fd9\u4e2a\u5c0f\u5de7\u800c\u5f3a\u5927\u7684\u6a21\u5757\u7531\u4e00\u4e2a\u5e26\u955c\u5934\u7684\u9635\u5217\u5149\u5b66\u4f20\u611f\u5668\u548c\u5185\u7f6e\u7684\u5377\u79ef\u795e\u7ecf\u7f51\u7edc\u63a8\u7406\u6838\u5fc3\u7ec4\u6210\u3002mVMR1108\u6a21\u5757\u8fd8\u914d\u5907\u4e86\u4e24\u4e2a\u4f5c\u4e3a\u95ea\u5149\u706f\u7684\u7ea2\u5916\u6216\u767d\u5149LED\u706f\u73e0\u3002\u5982\u4e0b\u56fe\u6240\u793a\uff0c\u9ed8\u8ba4\u60c5\u51b5\u4e0b\uff0cLED\u706f\u73e0\u4f4d\u4e8eLED1\u548cLED2\u5904\u3002\u5b83\u4eec\u4e5f\u53ef\u4ee5\u79fb\u52a8\u5230\u6807\u8bb0\u4e3aLED3\u548cLED4\u7684\u7a7a\u7f6e\u710a\u76d8\u4e0a\u3002<br \/>\nmVMR1108\u53ef\u4ee5\u5728\u8f83\u77ed\u7684\u7126\u8ddd\u5185\uff08\u6700\u5c0f\u4e3a2\u5398\u7c73\uff09\u8bfb\u53d6\u6570\u636e\uff0c\u914d\u5907\u7684\u5927\u89c6\u573a\u955c\u5934\u9002\u5408\u8bfb\u53d6\u5404\u79cd\u7c7b\u578b\u7684\u4eea\u8868\u3002<\/p>\n","category_list":"","author_info":{"name":"","url":""},"comments_num":"0 comments","tiered_pricing_type":"fixed","tiered_pricing_fixed_rules":[],"tiered_pricing_product_settings":{"layout":"default","base_unit_name":{"singular":null,"plural":null},"default_variation":null},"tiered_pricing_minimum_quantity":null,"tiered_pricing_roles_data":[],"tiered_pricing_percentage_rules":[],"_links":{"self":[{"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/product\/1144"}],"collection":[{"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/comments?post=1144"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/media\/1145"}],"wp:attachment":[{"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/media?parent=1144"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/product_cat?post=1144"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/vegesense.net\/en\/wp-json\/wp\/v2\/product_tag?post=1144"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
