Additionally, the mobile setup using the Blink app is covered for real-time data visualization. The tutorial is a step-by-step guide, perfect for beginners looking to explore IoT technology and build their own environmental monitoring system.

Takeaways

😀 The project involves creating a heart monitoring system using IoT, utilizing an ESP32 microcontroller and a DHT 11 sensor.
😀 The hardware setup includes jumper wires, a USB cable, and the ESP32, which connects to the internet via Wi-Fi.
😀 In the Blink platform, the user sets up a new template called 'Monitoring Di Hati 11' and selects ESP32 as the hardware and Wi-Fi as the connection method.
😀 Two data streams are created in Blink: one for temperature (Celsius) and one for humidity (percentage).
😀 The system allows setting units for temperature (Celsius) and humidity (percentage), with additional settings for precision and display options.
😀 The interface allows customization with widgets, such as gauges for temperature and humidity, and charts to visualize the data.
😀 The program's template on Blink includes a device name, pin assignments, and the DHT sensor configuration for temperature and humidity monitoring.
😀 The program uses libraries for the DHT sensor and Blink, with a serial monitor running at 115200 baud rate to display live data.
😀 The Blink app is configured to connect to the device and display data from the sensors in real-time on a mobile dashboard.
😀 After configuring the device and the app, the user connects to the device through Wi-Fi, finalizes the setup, and sees the monitoring system live on the mobile dashboard.

Q & A
