Low-cost Prototype for IoT-based Smart Monitoring through Telegram

Surveillance systems have been becoming an essential part of restricted areas, industries, organizations, and homes for automation as well as security purposes. Nowadays, a variety of surveillance systems are available in the market with motion detection (video) or human detection (image) facilities. But, the installation of such surveillance systems will cost huge amounts, and traditional CCTV cameras can only record live video. In this work, a prototype of the hardware and software implementation of the cam motion alert has been developed using Espressif’s latest microcontroller ESP32. Internet of Things (IoT) is an ongoing development of the Internet by which everyday ‘things’ objects have communication capabilities that allow them to send and receive data. This article presents a lowcost prototype of the smart monitoring system developed by using a motion-triggered image-capturing technology and a Passive Infrared (PIR) sensor. The motion trigger and alert camera consist of a motion sensor along with a vibration sensor that captures images using an ESP32 cam module. The PIR sensor detects a slight movement, immediately it wakes up the ESP32 cam, which will capture the human image and send it to an authentic telegram account anywhere in the world using a continuous Wi-Fi connection.
