This system monitors the amount of capacity used in given Buffer Stocks at various locations on a dashboard. It also provides a rough estimate of the weight of the stocked food. This system has two modules namely an Analyzer module and a Security Module. The Analyzer module is the main part that monitors the warehouse and uploads to a remote server. The security module is a basic PIN code-based entry system to secure the premises.

Security system:This project makes a use of Arduino uno microcontroller. Keypad is uses to enter the password. If the password is matched with the stored password Arduino will opens the door through servo motor. Otherwise, it’s not possible.

Stock section: This system makes a use of two ultrasonic sensors is uses to monitors the percentage of stock at various locations. DHT11 is uses to monitor the temperature and humidity values. LCD is uses to display the percentage of stock, temperature and humidity values. ESP32 module has inbuilt wi-fi is uses to upload the data into the thingspeak cloud along with date and time.

 

The features of the project are:

1. Automatic buffer stock % detection and monitoring.
2. Monitoring sensor data buffer % on LCD module.
3. Using IOT thingspeak cloud platform to upload the data.

The major building blocks of this project are:

1. Power Supply
2. Arduino UNO Micro Controller.
3. ESP32 module.
4. Ultrasonic sensors.
5. Keypad.
6. Servo motor.
7. LCD display.
8. DHT11
9. LED indicators.

Software’s used:

1. Arduino IDE STUDIO compiler for Embedded C programming.
2. Express SCH for Circuit design.
