<\/a><\/p>\nI followed the guide found here<\/a><\/p>\n However, i was having a problem by importing the mcp3008 module in the Python shell. It was giving me the following error<\/p>\n Googling a bit, i came across the solution here<\/a>. All i had to do was to remove the black listed SPI modules in I tested my setup by dipping the moisture sensor in water. When not in water, I would get a value of 1023. When fully dipped in water, it would be floating from 450 to 470. To get the readings in terms of percentage, i used the following formula\/code<\/p>\n Wo wo wo! Wait! Why using Windows???<\/p>\n Long story! Infact, i’m using Putty on Windows 7, ssh’ed in a virtual Ubuntu Server in Virtual Box from which i shh’ed to my Raspberry Pi. To summarize: Windows 7 > Ubuntu Server (Virtual) > Raspberry Pi<\/p>\n Who do such a thing? Because Putty was not able to connect directly to the Raspberry Pi. My Git Bash also failed for dunno what reason. Had to use a virtual Linux as middleman. lol \ud83d\ude00<\/p>\n Neways, now i plan in getting a temperature and other sensors (pH maybe) in the mix too. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":" I had bought a moisture sensor for quite a long time. But i didn’t have an Analog-to-Digital converter. I hence bought a MCP3008. But then, i didn’t have a breadboard and wires to connect my equipment. Today i finally managed to get everything and build it \ud83d\ude00 I followed the guide found here However, i … Continue reading Moisture Sensing with Raspberry Pi<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[167],"class_list":["post-2263","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-raspberry-pi"],"_links":{"self":[{"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/posts\/2263","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/comments?post=2263"}],"version-history":[{"count":2,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/posts\/2263\/revisions"}],"predecessor-version":[{"id":2267,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/posts\/2263\/revisions\/2267"}],"wp:attachment":[{"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/media?parent=2263"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/categories?post=2263"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nayarweb.com\/blog\/wp-json\/wp\/v2\/tags?post=2263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}>>> import mcp3008
