Abstract

• Microwave motion sensor HW MS03 utilizes the Doppler shift phenomenon due to the relative motion. The sensor detects the slight movement and it triggers the microprocessor to operate the various functions. In this research, microwave motion sensor detects the motion of object and then it sends the digital signal to the microprocessor. The capturing the photograph and the Gmail with photograph sending to the specified address are implemented by microprocessor. ESP32_CAM is the microcontroller which is attached with OV2640 camera module, Wi-Fi and dual mode Bluetooth. It is reliably suitable to detect the trigger signal from microwave motion sensor, to capture the photograph and to connect the internet via Wi-Fi for sending the email. By using deep sleep mode which is one of the special features of ESP32_CAM, the energy consumption is reduced. After implementation of all functions, the processors and digital peripherals connection are in sleep mode until the next motion signal is detected. This system can be used in security monitoring, intelligent home appliances control system due to low energy consumption, cost effective system and reliable operation.
