Weekly Progress
This week our team engineering show touch switch
circuit and RGB to product design team. I think that it’s not
stable so, I was searching for new technique for make touch
switch circuit. I was found IC WB2080B, it is touching IC.
The WB2080 is a touch pad detector IC which offers 8
touch keys. The touching detection IC is designed for
replacing traditional direct button key with fixed pad size. Low
power consumption and wide operating voltage are the
Figure 1: WB2080B Touching IC Application contact key features for DC or AC application.
The main remote control technology used in the home is infrared. The signal between a remote control
handset and the device it is controlling are infrared pulses, which are invisible to the human eye. The
transmitter in the remote control handset sends out a pulse of infrared light when a button is pressed on the
handset. A transmitter is often a light emitting diode (LED) which is built into the pointing end of the remote
control handset. The infrared light pulse represents a binary code that corresponds to a certain command,
such as (power on). The receiver passes the code to a microprocessor, which decodes it and carries out the
command.
Engineering Analysis
Strong Point - A WB2080 was used in any product that use interface by touched, so I think it will we stable.
Week Point - A WB2080 is surface mount. It is hard to make with PCB.
Next Week Job
Next week, we will test circuit with IC WB2080 after I received its.
