Circuit Documentation
Summary of the Circuit
This circuit integrates an ESP32 microcontroller with a GP2Y1010AU0F dust sensor. The ESP32 is a versatile microcontroller with Wi-Fi and Bluetooth capabilities, while the GP2Y1010AU0F is an optical air quality sensor designed to detect dust particles. The ESP32 reads the output from the dust sensor and controls its operation. The connections between the two components allow for data acquisition from the sensor and power management.
