<p dir="auto">Here is when it was working just fine:</p>
<p dir="auto"><img src="/assets/uploads/files/1602238391379-121246373_1438786996319095_4884810211685659355_n.jpg" alt="0_1602238388832_121246373_1438786996319095_4884810211685659355_n.jpg" class=" img-fluid img-markdown" /></p>
<p dir="auto">But now it starts with values around one hundred and then goes to decrease all PM values until all of them got Zeros in a few seconds while the values of the humidity and temperature are correct all the way.</p>
<p dir="auto">Here is where it starts now:</p>
<p dir="auto"><img src="/assets/uploads/files/1602238470523-121084701_1004762500040541_5529716174307868476_n.png" alt="0_1602238451306_121084701_1004762500040541_5529716174307868476_n.png" class=" img-fluid img-markdown" /></p>
<p dir="auto">And here is what it be after less than a minute:</p>
<p dir="auto"><img src="/assets/uploads/files/1602238508723-121109008_340026530652380_1600196707044937137_n.png" alt="0_1602238492807_121109008_340026530652380_1600196707044937137_n.png" class=" img-fluid img-markdown" /></p>
<p dir="auto">Have any one got a same issue? and how he solved it if there is.</p>
<p dir="auto">Keep in mind that I have tested the module with another <strong>Basic Core</strong> and used both of the code in the Arduino M5Stack examples and the appropriate  EasyLoader "<em>EasyLoader_PM2.5_APPLICATION</em>" from <a href="https://m5stack.oss-cn-shenzhen.aliyuncs.com/EasyLoader/Windows/APPLICATION/EasyLoader_PM2.5_APPLICATION.exe" target="_blank" rel="noopener noreferrer nofollow ugc">M5Stack official website</a> and still getting the same issue.</p>
