Introduction
The miniature methane sensor SJH-100A-L is based on NDIR technology with dual beam design, which is superior to semiconductor and catalytic technology, and can detect 0~100%Vol methane (CH4) concentration.
It has the advantages of low power consumption, accurate measurement, convenient operation, long lifespan, etc.
With a low power IR source, SJH-100A-L can achieve average current consumption 16mA which make the sensor suitable for battery or solar powered IoT device. It's an energy-efficient, reliable and accurate solution for industrial application.
Features
1.NDIR technology
2.Matrix calibration ensure excellent accuracy
3.Low power consumption
4.Temperature & humidity compensation
5.High humidity alarm with self diagnostics design
6.Digital and analog output (UART-TTL/DA output)
7.Long lifespan (10 years)
