First, size: 32mm X22mm X24mm L * W * H
Second, the main chip: LM393, MQ-2 gas sensor probe
Third, the working voltage: DC 3.0-5.5V
IV characteristics:
                  1, with the signal output instructions;
                  2, the dual signal output; (analog output, and TTL level output)
                  3, TTL output valid signal is low, which can be accessed directly connected to Microcontroller IO port;
                  4, 0 ~ 5V analog output voltage, the higher the voltage the higher the concentration;
                  5, liquefied gas, butane, methane, smoke, etc. have good sensitivity;
                  6, long life, good stability;
                  7, with fast response and recovery characteristics
V. Application:
     Family or the factory for the gas leak detection device, suitable for liquefied petroleum gas, butane, propane, methane, ethanol, hydrogen, smoke and other monitoring devices to detect flammable gases, fumes 300 to 10000ppm
