In this project, a bank locker system is presented that includes a weight threshold sensor as
a crucial element for increased security. The system makes use of an Arduino Uno microcontroller, a
weight threshold sensor, a GSM SIM900A module, and a fingerprint R307 sensor for biometric
authentication. The solenoid lock open mechanism is only activated by the weight threshold sensor
when a predetermined set weight is applied. The system's operations are managed and coordinated by
the Arduino Uno, which acts as the system's central processing unit. By verifying users' identities
using their fingerprints, the R307 sensor ensures secure access to the lockers. The GSM SIM900A
module allows for real-time locker system monitoring and control via SMS instructions, enabling
remote management and delivering prompt notifications and alerts. The system includes a weight
threshold sensor to provide the highest level of security. It works by recognising when something has
been placed on it and measuring the weight in relation to a predetermined threshold value. The
inclusion of the weight threshold sensor improves the security of the bank locker system. The
technology improves ease and lowers the chance of uninvited entrance by doing away with the need
for conventional keys.
