M5Stack® TVOC/eCO2 Gas Unit (SGP30) Digital Multi-Pixel Gas Sensor Unit Air Quality Monitoring eCO2 Concentration Module

Description TVOC eCO2 mini Unit is a digital multi pixel gas sensor unit with integrated SGP30 It mainly measures various VOC volatile organic compounds and H2 in the air It can be programmed to detect TVOC total volatile organic compounds and eCO2 equivalent carbon dioxide reading Concentration measurement Typical measurement accuracy is 15 within the measurement range the SGP30 reading is internally calibrated and output which can maintain long term stability SGP30 uses I2C protocol communication with on chip humidity compensation function which can be turned on through an external humidity sensor If you need to obtain accurate results you need to calibrate according to a known measurement source SGP30 has a built in calibration function In addition eCO2 is calculated based on the concentration of H2 and cannot completely replace true CO2 sensors for laboratory use Features TVOC eCO2 concentration detection I2C communication 0X58 Outstanding long term stability Humidity Compensation 2x LEGO™ Hole HY2 0 4P interfacePackage Included 1x TVOC eCO2 Mini Unit 1x HY2 0 Cable 5cm Applications Air quality monitoring eCO2 concentrationSpecification SpecificationParameterMeasurement rangeEthanol 0 1000ppm H2 0 1000ppm TVOC 0 60000 ppb eCO2 400 60000 ppmTVOC eCO2 Sampling rate1HzTVOC eCO2 ResolutionTVOC 1 6 32bbp eCO2 1 3 9 31ppmProtocolI2C Net Weight4gGross Weight8gProduct Size24 24 13mmPackage Size35 36 18mmCase materialPlastic PC EasyLoader Click
