Hydrogen Sensor Module (MQ8) Neodymium magnet With waterproof probeIntroduction: This is a simple to use hydrogen sensor, suitable for sensing hydrogen concentrations in the air. The MQ 8 can detect hydrogen gas concentrations anywhere from 100 10000ppm. This sensor has a high sensitivity and fast response time. Detects Hydrogen(H2), poorly sensitive to LPG, alcohol, cooking steam, CO. Features : Main chip: LM393 Working voltage: DC5V Load resistance: 10K Dual signal output (TTL level output and Analog output) TTL
