ESP32 Gas & Smoke Detection Alarm System Kit

The ESP32 Gas & Smoke Detection Alarm System Kit is a complete DIY electronics project kit for building a gas and smoke detection alarm system using an ESP32 development board. The kit includes an MQ-2 gas/smoke sensor, DHT11 temperature & humidity sensor, 0.96″ I2C OLED display, buzzer, LEDs, transistors, breadboard, jumper wires, 18650 battery and holder.

The MQ-2 sensor can be used to detect smoke and several combustible gases. The ESP32 processes the sensor readings and can activate the buzzer and LED indicators when programmed detection thresholds are reached. The OLED display can show sensor readings and system status.
