Smart ATM Security and Alert System with Real-Time Monitoring

The growing adoption of automated teller machines (ATMs) worldwide, ensuring the security ATM transactions and protecting customer data has become a critical concern for banking industry. In this research paper, we proposed an Internet Things (IoT) based system using NodeMCU ESP8266 module, PIR (Passive Infrared) sensor, LCD display with I2C interface, Telegram app. utilizes which is low-cost Wi-Fi enabled microcontroller, as main controller system. sensor used to detect motion or presence near ATM, can potentially indicate unauthorized access. interface provide real-time status information about such Motion Detected NO Motion. When detects any suspicious activity module sends notification owner personnel via includes details detected activity, allowing take immediate action. real- time alerts enable prompt response potential breaches help prevent access ATM.
