September 21, 2025 – An innovative weather monitoring system powered by IoT has been developed by IoT Engineer Lins Paulson, who successfully integrated his ESP32-based project with the Favoriot IoT Platform, taking his prototype to a new level of professionalism and scalability.
The project, inspired by a suggestion from Dr. Mazlan Abbas, CEO and Co-Founder of Favoriot, demonstrates how developers can leverage local platforms to create impactful real-time monitoring solutions.
Project Overview
Paulson’s system uses an ESP32 DevKit V1 paired with a DHT11 sensor to capture live temperature and humidity data. The readings are securely transmitted to Favoriot’s cloud via REST API over HTTPS, visualised through an interactive dashboard, and linked to automated email alerts that are triggered only under abnormal environmental conditions.
Key Development Steps:
- Migration from Arduino IDE to VSCode using ESP-IDF, adopting a more structured development workflow.
- Implementation of secure REST API communication with Root CA certificate validation.
- Refinement of Favoriot’s alert logic to prevent false alarms, ensuring notifications are sent only under critical thresholds (e.g., temperature above 30°C combined with humidity below 30%).
Technical Stack:
- Hardware: ESP32 DevKit V1, DHT11 sensor
- Software: VSCode with ESP-IDF
- Connectivity: Wi-Fi (2.4 GHz), REST API over HTTPS
- Cloud Platform: Favoriot Platform
- Visualisation: Favoriot interactive dashboard
Learning Outcomes
Through the project, Paulson gained hands-on experience with ESP-IDF, secure HTTPS-based API integration, and automated IoT-triggered notifications. He also enhanced his understanding of REST APIs in embedded systems, an essential skill for modern IoT engineers.
Challenges & Solutions
One of the major hurdles was configuring HTTPS certificate validation within the ESP-IDF environment. Once resolved, the ESP32 was able to transmit data securely to Favoriot’s platform. The project also required fine-tuning of alert parameters to ensure actionable and reliable notifications.
Paulson described the project as both a learning journey and a practical demonstration of how cloud IoT platforms, like Favoriot, can accelerate development, improve system reliability, and make IoT solutions more accessible.
This initiative highlights how engineers, guided by industry leaders, can push the boundaries of innovation by utilising accessible IoT platforms, thereby bridging the gap between prototype and professional deployment.
