## Description
**PDM** is a digital MEMS silicon-based microphone based on PDM (Pulse Density Modulation). The microphone has high signal-to-noise ratio, high sensitivity, low power consumption, anti-radio frequency interference, smooth frequency response and other characteristics. It automatically switches the microphone state according to the clock frequency (power down/activate/sleep)and can be widely used for audio data collection on wearable devices and smart digital devices.

## Description
**TVOC** 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.

## 描述
**TVOC** 是一款数字式多像素气体传感器单元，内部集成SGP30,主要测量空气中的各种VOC(挥发性有机化合物)和H2，通过编程可实现对TVOC(总挥发性有机化合物)和eCO2(二氧化碳等效)浓度的测量，在测量范围内典型测量精度为15%,SGP30读数经过内部校准输出，可保持长期稳定。SGP30采用I2C协议通讯，带有片上湿度补偿功能，可通过外接湿度传感器开启该功能。如果您需要获取精确的结果，您需要根据已知测量源进行校准，SGP30内置校准功能。此外，eCO2是根据H2浓度计算得出的，并不能完全替代CO2传感器。
