Gas and Smoke Detector Sensor module for Arduino ProjectsDetects dangerous gas and smokeThe MQ-2 is a compact gas and smoke sensor which detects butane, propane, methane, alcohol, hydrogen and smoke. Suitable for home, factory air quality monotoring applications. Specifications:Dimension: 32 X 22 mm Gas Sensor: LM393, MQ-2 Working voltage: DC 5 V Features: Dual signal output (analog output, and TTL level output) TTL output valid signal is low. (Low-level signal can be directly connected to the microcontroller) 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage. High sensitiity to liquefied petroleum gas and natural gasLong life and reliable stability Rapid response and recovery characteristics
