MQ-2 Gas Sensor Module For H2, LPG, CH4, CO, Smoke or Propane Detector Module ESP32 (38 Pin) WiFi + Bluetooth NodeMCU-32 Development Board The output is an analog

The output is an analog voltage signal that varies proportionally with hydrogen concentration

and maintenance-free performance with no brush wear

Always use seamless aluminum tubing rather than welded tubing to avoid joint failure at weld points

sufficient for multiple medium-sized projects or single large-scale manufacturing runs
