An IoT-enabled multi-gas detection system designed for basement garages and indoor environments where toxic gases can accumulate. The system monitors Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), Methane (CH₄), and LPG (Propane/Butane) using ESP32 and gas

Monitoring CH4 gas concentration, temperature, and humidity in real-time with emergency fan control.

Greenhouse gases monitoring (CO2 and CH4)

Leaked Natural Gas Level (Percent) of our Kitchen (Location: Tehran-Iran)

Detectors of smoke and flammable gases (ethanol (MQ3), hydrogen (MQ8), methane, smoke, etc (MQ2) and others) on Arduino Nano and ESP-01

verifies industrial air pollution

This is a particle photon connected to a DHT22 Temperature/Humidity Sensor, an MQ-4 Methane Gas Sensor and an MQ-7 CO sensor to monitor my home.
