Building an ESP32 Email Alert System with Sensor Alarms

Want to monitor physical environments remotely and receive instant notifications when something goes wrong? The ESP32 is a powerful, low-cost microcontroller with built-in Wi-Fi, making it the perfect tool for building automated alert systems. In this course, you will learn how to interface sensors with the ESP32, read real-world environmental data, and write clean code to send automated email alerts based on custom conditions. What you will learn: Understand the fundamentals of ESP32 architecture, GPIO pins, and Wi-Fi connectivity; Configure secure SMTP clients on the ESP32 using modern encryption standards like SSL/TLS; Interface analog and digital sensors to measure temperature, humidity, or motion; Implement conditional logic in code to trigger alerts only when specific thresholds are breached; Manage email authentication safely using modern app-specific passwords; Structure your firmware to run reliably, prevent spam alerts, and handle network disconnections. You will start with fundamental IoT concepts and ESP32 hardware basics before moving step-by-step through Wi-Fi configuration, sensor integration, and secure email dispatch. This course is designed for beginners interested in IoT, electronics, and home automation, with no prior hardware programming experience required.
