Summary

This circuit integrates an Arduino Nano microcontroller with a SIM800L EVB GSM module, a GPS NEO 6M module, and multiple TCRT 5000 IR sensors. The Arduino Nano serves as the central processing unit, interfacing with the GSM module for cellular communication, the GPS module for location tracking, and the IR sensors for detecting proximity or measuring the intensity of infrared light.
