IoT based Smart Jar using NodeMCU and ESP8266

This IoT based smart Jar allows us to keep track of the stocks, and it is easily accessible from using the internet. The Jar includes an ultrasonic sensor at the top of it and uses the ultra-sonic reflected waves to figure out at what extent the Jar is filled and how much space is left inside the jar. Whenever the amount of content changes in the jar, it is sensed by the NodeMCU, and the same is updated on the web server.
