TGS2602 Air Quality VOC & Odorous Gas Sensor Module (Semiconductor Gas Detection Sensor)

The TGS2602 Air Quality VOC & Odorous Gas Sensor Module is a high-sensitivity gas detection module designed to monitor volatile organic compounds (VOCs) and odorous gases in indoor environments. Based on the TGS2602 semiconductor gas sensor, it detects low concentrations of airborne contaminants generated by solvents, tobacco smoke, cooking fumes, and other odor-producing substances. The module provides an analog output for easy interfacing with Arduino, ESP32, Raspberry Pi (via ADC), STM32, and other embedded platforms.

Its compact design and reliable sensing performance make it ideal for indoor air quality monitoring, smart home automation, environmental monitoring, and industrial safety applications.
