1 PC MH-Z9041A TDLAS Laser Methane(CH4) Sensor

MH-Z9041A laser CH4 gas sensor (hereinafter referred to as the sensor) is a domestic methane sensor, based on tunable laser gas absorption technology (TDLAS) technology to detect methane gas, internal use of cross-beam light path structure, with excellent gas selectivity, no oxygen dependence, water vapor resistance. Anti-poisoning, long life, etc. Built-in temperature control algorithm, temperature compensation algorithm, to achieve accurate measurement of methane gas; With serial port output interface, easy to use. The sensor is a high performance sensor which combines mature laser gas absorption detection technology with stable optical path design and circuit design. Application  Methane gas alarm for home use Features Resistance to water vapor, no poisoning Response to CH4 gas only, no response to other gases No need calibration, long lifespan High accuracy, resolution can reach 0.1%LEL UART output way Specifications Model No. MH-Z9041A Detection Gas Methane CH4 Power supply DC (3.2-3.6) V Working current <300mA Interface level 3.0V Detection Range 3-100%LEL (can be customized) Detection Accuracy ±3%LEL @25℃ Output signal Serial port (UART) (TTL level 3.0V) Warm-up time 15s Response time T90< 15s Working conditions -13~58℃① 0-95%RH(no condensation)  80kpa~116kpa Storage temperature -20~60℃ Size 76.5mmX21mmX14.1mm Weight < 20g Life > 10 years Detection range and accuracy Gas Name chemical formula Detection Range Resolution Accuracy Methane CH4 3-50.00%LEL 0.1%LEL 3-50.00%LEL: ±(3%LEL)@25℃ >50.00%LEL:±(5%LEL)@25℃ Methane CH4 3-100.00%LEL 0.1%LEL ±(3%LEL)@25℃   * The description and specifications might be changed without notice.
