What i want to do is when the moisture of the soil gets decreased i just want to give water to the plants or if i can just get a notification about the moisture would be fine. I have very little knowledge about this things. I have raspberry pi and moisture sensor module but i don't know about the connections and working of the moisture sensor module. What is the analog and digital in that module?. How can i get the levels of moisture using python script? Is there any other modules which i need to purchase?
