商品特色 詳盡技術資料請見原廠或供應商 https://www.sparkfun.com/products/18345 [ https://www.sparkfun.com/products/18345 ] 料號：SEN-18345The SparkFun SGP40 Air Quality Sensor provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion＇s CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.The SGP40 does not return specific concentrations or VOC gases. Instead, it outputs a digital value based on common VOC gases present in an indoor environment and this value can be combined with Sensirion＇s VOC Index Algorithm to detect the relative intensity of VOC events in relation to the average readings in a 24hr period. Think of the SGP40 as a sensitive electronic nose for detecting VOCs in a room.The SGP40 communicates via I2C so naturally we broke out the pins on the sensor to Qwiic connectors so you can easily connect it to SparkFun＇s ever growing Qwiic Ecosystem!The SparkFun Qwiic Connect System [ https://www.sparkfun.com/qwiic ] is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.Get Started with the SGP40 Air Quality Sensor Hookup Guide [ https://learn.sparkfun.com/tutorials/air-quality-sensor－－－-sgp40-qwiic-hookup-guide ]Features:Uses I2C interface (Qwiic-enabled)I2C Address: 0x592x Qwiic connectorsOperating voltage range:1.7V - 3.6V (Typ. 3.3V)The Qwiic interface provides 3.3VTypical current consumption:2.6mA during continuous operation (at 3.3V)34µA when idle (heater off)Output signal:Digital raw value (SRAW): 0 - 65535 ticksDigital processed value (VOC Index): 0 - 500 VOC Index pointsSwitch-on behavior:Time until reliably detecting VOC events:
