VOC Sensor Module, 5-500 ppm, Analog and TTL level Output, MQ138 Sensing Element

The L-com SRAQ-G020 gas sensor module is used to detect the presence and concentration of various organic vapors including toluene, acetone, ethanol, formaldehyde, and hydrogen. This device requires a 5 VDC ± 0.2 V power supply, a < 150 mA working current, and has a detection range of 5-500 PPM. Our 5 VDC ± 0.2 V sensor module is well suited for VOC gas alarms, industrial gas leakage detectors, portable VOC, and other areas where VOC concentrations are of concern.

The various organic vapors including toluene, acetone, ethanol, formaldehyde, and hydrogen sensor module has 4 pin male header which allows for easy integration into gas detection devices. The sensor module features a MQ138 sensing element with good sensitivity and selectivity to various organic vapors including Toluene, acetone, ethanol, formaldehyde, and hydrogen, which makes it less affected by temperature and humidity. This SRAQ-G020 sensor module has a analog and TTL level output modes and it operates at temperatures ranging from -10 to 50 Degrees C.
