PURPOSE: A smart touch type automatic faucet device is provided to automatically and stably control the supply of water by measuring the amplitude of reference voltage changed when a user touches a hanger housing. CONSTITUTION: A smart touch type automatic faucet device comprises a hanger housing(100), a spray(200), a body(400), a control box(600), and an LED unit. The hanger housing is formed using a non-insulation material. The spray is formed on one side of the hanger housing. The body is formed on the other side of the hanger housing and has a cold and hot water control valve. The control box has an amplitude modulation measurement unit, an AD conversion unit, a solenoid valve, a battery monitoring unit, and a temperature measurement unit. The amplitude modulation measurement unit measures the amplitude modulation of a capacity. The AD conversion unit converts the measured value into a digital signal. The solenoid valve supplies water. The battery monitoring unit measures the residual capacity of a battery unit. The temperature measurement unit senses the temperature of the water supplied from the solenoid valve. The LED unit displays the measured residual capacity of the battery unit and the measured temperature value. |
