ALLNET 4duino MQ-6 Flüssiggas Sensor

ALLNET 4duino MQ-6 Flüssiggas Sensor Product Model: OKY3332 MQ-6 Liquefied Petroleum Gas Sensor Liquefied Isobutane Propane Gas Detector Product Description Main chip: MQ-6 gas sensor. Dual signal output (TTL level output and analog output). TTL output valid signal for low level. (when the low output electric signal lights at 4. ordinary times, can be directly pick up SCM). Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage. High sensitivity to hydrogen. Can be resistant to ethanol steam, LPG (petroleum), smoke interference. Has a long service life and reliable stability. Quick response recovery features. With a signal output instructions. Working voltage: DC5V. Size: 35 mm X20mm.
