DEVICE FOR DETECTING APPROACH OF OBJECT AND METHOD FOR DETECTING APPROACH OF OBJECT USING SAME

摘要

According to one embodiment of the present invention, a device for detecting the approach of an object comprises: a sensor strip with a variable capacitance value; a plurality of RF oscillators connected to the sensor strip to generate oscillation frequencies with different phases; and an MCU detecting an object approaching the sensor strip using divided oscillation frequencies, and analyzing the variation of the of the divided oscillation frequencies and resetting a switching group to oscillate the oscillation frequencies.;COPYRIGHT KIPO 2020
