Abstract

Abstract: The core of environmental pollution detection is quartz crystal microbalance and data acquisition circuit. Under certain conditions, when the quartz crystal vibration surface adsorbs other substances, the natural frequency of quartz crystal vibration changes with the size of adsorption mass, and the frequency is converted into identifiable micro-mass data through the data acquisition circuit. This project USES quartz crystal to detect environmental pollution.
