Now, let's upload this value to a cloud platform so that we can monitor the status of our inventory management system from anywhere in the world with the help of our inventory management software. This way, we can calculate the number of packages available in the inventory.
We can measure the total weight, and we can do all the necessary calculations with the help of a microcontroller. The answer to that question is simple, we will use a load cell.

So, the next question is, how to calculate or how to measure the total weight. In the mentioned example, we will get 10 packs. For example, if the weight of 1 package is 10 grams and the total weight of the shelf for inventory is 100 grams, then we can easily calculate the number of packets available on the shelf by dividing the total weight by the weight of one individual pack. To know the number of packets available in the inventory, we have to know the total weight and the weight of an individual packet. You can check all the ThingSpeak and ESP2866 related projects by following the respective links.Īutomatic Inventory Management System - Working We have previously used ThingSpeak with ESP8266 to build Air Quality Monitor system, IoT weather station, and Smart Street light. So without further ado, let's get started. And finally, we will use another popular technology, IFTTT to send an email if a product quantity goes below a certain level. And to make it convenient, we will incorporate IoT technology with the ThingSpeak cloud platform so that the store owner can monitor the inventory from his home/office. This is why in this tutorial, we thought of building an Internet of Things and sensors based Automated Inventory management system with the help of the popular NodeMCU ESP8266 microcontroller, which can automatically detect the number of goods present on a shelf or, can accurately provide the weight of a particular good.
