Tvoc Air Quality Sensor Module, 3.3 VDC Working Voltage, TTL Output

The L-com SRAQ-D725 low power air quality sensor module is used for detecting volatile organic compound ( VOC), CO2 and HCHO gas. This sensor module is well suited for portable T VOC detector, air quality monitoring, HVAC industry, smart buildings, and other areas where T VOC is a concern. This shock and vibration resistant device provide high sensitivity, good precision, small form factor, quick response, and short preheat time.

The low power air quality sensor module has a pre-programmed algorithm which is used to estimate CO2 and HCHO gases concentrations based on overall VOC concentration. This SRAQ-D725 module measures the concentration in real-time and gives output via UART protocol. This sensor has 3.3 VDC working voltage and operates at temperatures ranging from -5 to 50 degrees C with non-condensing 0 to 100% RH humidity.
