Gas and Dust Sensor

These sensors detect combustible gases (like LPG, methane, and smoke), specific gases such as CO2 or alcohol vapor, or airborne dust and particulate concentration, converting a chemical or physical property into a readable electrical signal. Common uses include DIY gas-leak alarms, air-quality dashboards, and greenhouse ventilation triggers. Most gas sensors need a brief warm-up period after power-on before readings stabilize.
