Home-Security-Alarm-System-using-SIM800L-GSM-module
Home security systems work on the simple concept of securing entry points into a home with sensors that communicate with the SIM800L GSM Module via serial communication to make a call to the pre-programmed mobile number.
Password_Based_Door_Lock_System
Here in this project called password based door lock system; 4*4 keypad matrix is used to take input. Users have to enter the correct password to unlock the door. When the password is entered by the user, it is compared with the predefined password. If the password entered is correct then the system will open the door latch with the help of servo motor.
Sanitizer_Dispenser
The Contact-less hand sanitizer dispenser is an infrared motion sensor-based dispenser. It is used to dispense any alcohol-based sanitizer. It has a touch-less operation, which makes it convenient for people to use it fearlessly and confidently. It facilitates the sanitization process. You may call it as an automatic or touch-free sanitizer dispenser. When hands are placed in the proximity of the sensor, the infrared sensor detects the object (hand). This is then used as an input for the Arduino Uno. If the object is within the range of IR sensor then the pump gets activated and dispenses the designated amount of sanitizer.
