HYDROGEN SULPHIDE SENSOR User Guide for SRAQ-G215 Product Description The SRAQ-G215 gas sensor detects the presence and concentration of Hydrogen sulfide and other sulfur based organic vapors. Integrated circuitry produces a non-linear voltage signal corresponding to the gas concentration. With a detection range of 1 to 200 ppm, the SRAQ-G215 sensor module can be integrated into portable H S detectors or other air quality monitoring equipment.

Electrical Diagram 24V and GND are the power interface, D1 is the power indicator. Aout is the analog output interface, VR2 is the signal trimmer potentiometer. VR1 is the magnification (the output of 0-5V and 0-10V can be adjusted freely through this potentiometer). The load resistance of the sensor composed of R7 and RP2 potentiometer is in parallel relationship (can be changed by user).
