[shortdesc]Application:​​Widely used for HVAC refrigeration, air monitoring indoor, industrial process control and safety protection,agriculture and animal husbandry.Feature:High sensitivity, high resolution, fast response,Temperature compensation, excellent linear output[/shortdesc]Production Description:MH-440D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CH4/C3H8 in air and has good selectivity, stable performance, long life, also is independent of Oxygen. The inside temperature sensor could be used for temperature compensation. This miniature infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, micro machine workout and superior circuit design.It is convenient in use and also instead of catalytic component directly, widely used in various occasions with flammable and explosion hazard gas.Feature: High sensitivity, high resolution, fast response Output method: UART, analog voltage signal Temperature compensation, excellent linear output Excellent stability, Long lifespan Anti-poisons, anti-vapor interference Can replace catalytic type gas sensor directly Application:​Widely used for HVAC refrigeration, air monitoring indoor, industrial process control and safety protection,agriculture and animal husbandry. Main technical parameters: Detection Gas Propane (C3H8) WorkingVoltage 3.6~5VDC (Need to be powered by safety barrier) Average Current ＜85mA Interface Level 3.0V Detection range 0~2.00%vol (0-100%LEL) OutputSignal UART(3.0V) 0.4~2.0VDC Warm-up time 3 min Response time T90<30s WorkingTemperature -20°C ~ 60°C WorkingHumidity 0~95%RH(no condensation) Sizes Φ20×22.6mm Weight 35g Lifetime >5 years Defense Grade IP54 Power, communication terminal Intrinsic safety Ui=7.5VDC，Ii=265mA， Pi=0.5W，Ci=10μF，Li=0mH   ​Detection Gas Methane (CH4) WorkingVoltage 3.6~5.0VDC (Need to be powered by safety barrier) Average Current ＜85mA Interface Level 3.0V Detection range 0~10%vol(selectable, refer fig2.) OutputSignal UART(3.0V) 0.4~2.0VDC Warm-up time 3 min Response time T90<30 seconds WorkingTemperature -20°C ~ 60°C WorkingHumidity 0~95%RH(no condensation) Sizes Φ20×22.6mm Weight 35g Lifetime >5 years Defense Grade IP54 Power, communication terminal Intrinsic safety Ui=7.5VDC，Ii=265mA， Pi=0.5W，Ci=10μF，Li=0mH
