摘要（英）：

The invention discloses a micro-liquid sensing device and method. The device comprises a probe, a detection capacitor, a touch sensing module and an optical coupler, wherein the probe is connected tothe input end of the touch sensing module, the two ends of the detection capacitor are connected between the input end of the touch sensing module and the ground respectively, and the output end of the touch sensing module is connected with the input end of the optical coupler. According to the micro-liquid sensing device and method, slight voltage change in the detection capacitor is detected through the probe and the touch sensing module so as to detect micro liquid level or metal, and the detection precision is effectively improved while the cost is reduced; besides, the device can be usedin various detection environments by changing the probe, which is convenient and practical. The device can be widely applied to liquid level or metal detection.
