So what is it?

Smart-Health-track is a project built around the ESP32, a small wireless microcontroller commonly used in hobby and embedded projects. It collects environmental sensor data and the README frames it as a health tracking system. The hardware used includes a DHT22 sensor for temperature and humidity readings, an MQ135 sensor for air quality, a rain sensor, and an LCD display to show readings. The ESP32 connects all of these together and, according to the README, provides IoT connectivity, meaning the data can presumably be sent over a network. The project is developed using PlatformIO inside Visual Studio Code, which is a common setup for writing and uploading code to microcontroller boards. The README is brief and does not include wiring diagrams, setup steps, or details about how the connectivity or display features work.

Copy-paste prompts

Prompt 1

I have an ESP32 with a DHT22 and MQ135 wired up and PlatformIO installed in VS Code. Show me how to read both sensors and display temperature, humidity, and air quality readings on a 16x2 LCD.

Prompt 2

Using this smart-health-track ESP32 setup, help me add code to send sensor readings to an MQTT broker over Wi-Fi every 30 seconds.

Prompt 3

My MQ135 air quality sensor on the ESP32 is giving unstable readings right after power-up. What warm-up delay or calibration steps should I add to the setup function?
