Gas sensor This analog gas sensor has a small heating part with an electronical chemical sensor. It is suitable for indoor usage. The sensor can output exact values only after warmup phase. Caution: sensor gets hot while usage! SpecificationsMeasurement range300 - 10000 ppmMeasureable substancesCarbon monoxide (CO)Application areasDetecting gas leaks, gas alarm, robotic, microcontroller projectsCompatible withRaspberry Pi (with AD-converter), Arduino. etc.Special featuresHigh sensitivity which can be adjusted by potentiometer, quick reaction time, low temperature detection of gasAnalog OutputValues are processed by the microcontrollerDigital Outputthresholds can be setPinsVCC: Voltage supply 5V, GND: Ground, AOUT: Analog Output, DOUT: Digital OutputLoop voltage? 10 V DCHeating voltage5.0 V ± 0.2 VHeating resistance31 ? ± 3 ? at room temperatureHeating power? 350 mWSurface resistance of sensitive material2 -20 K? in 100 ppm COOperating temperature-20 - 50 °CDimensions52 x 20 x 13 mmWeig
