... plate and a metal oxide semiconductor material with low conductivity in clean air. When the detected gas exists in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of

VOC Sensor KGD - VOC - 100 Product Introduction The KGD - VOC - 100 air quality sensor module, based on MEMS gas-sensitive elements, is used to test the content of harmful substances in the ambient air and provides predicted relative equivalent concentration values of harmful substances. The test data is output through three methods: 4-level output, I2C interface communication, or UART interface communication. The surface of the MEMS...
