MS1100 Gas Sensor

1. Power supply voltage: +5V

2. AOUT: Analog output, voltage value change corresponding to gas quantity detected by chip, single chip can connect directly using ADC.

3. DOUT: Digital output is the result of comparing the output voltage values of AOUT and adjustable resistor, output semaphores 0 and 1.

4. Adjust the adjustable resistor of the module. When the output voltage of the adjustable resistor is less than AOUT, the output of DOUT is high level, while the LED lamp is on; On the contrary, DOUT output is low and the LED lamp is off.

That being said, it just produces an analog voltage signal based on it's readings.There's also the option to set a trigger event onboard if values exceed a certain level.I found it to be completely non-responsive to a direct blast from a Co2 canister.That isn't scientific fact, it's just my experience. I wanted to build an AC leak detector based on Co2.I will be moving up to the next level which is an SPI device. I expect it will make far more data available to my micro controller.I'd definitely be willing to select this module for an application without a micro controller.I don't know if I'd trust it for a safety response system. But I'm also not saying you can't. I haven't tested it in the fire/smoke detection range.It goes crazy from electronic cigarette vapor. It will also respond very slightly to a direct slow exhale of breath.Just be sure that this module will suit your needs. I require a more complex form of multi-molecular analysis which this simply isn't intended for.
