TTP223B CAPACITIVE TOUCH SENSOR

The TTP223 is a touch pad detector IC which offers 1 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application.

• Operating voltage 2.0V~5.5V
• Operating current @VDD=3V, no load, SLRFTB=1, At low power mode typical 1.5uA, maximum 3.0uA and at fast mode typical 3.5uA, maximum 7.0uA
• Operating current @VDD=3V, no load, SLRFTB=0, At low power mode typical 2.0uA, maximum 4.0uA and at fast mode typical 6.5uA, maximum 13.0uA
• The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V
• Provides Fast mode and Low Power mode selection by pad option (LPMB pin)Operating Temperature:-20 ~ +70 ℃

5V 1 CHANNEL RELAY MODULE

The module is uses SRD relay module to control high-voltage electrical devices. (maximum 250V).It can be used in interactive projects and can also be used to control the lighting, electrical and other equipment can be controlled directly by a wide range of microcontrollers and can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.

• Number of I/O Channels: 1
• Type: Digital
• Switching capacity available by 10A in spite of small size design for high-density P.C. board mounting technique.
• Control signal: TTL level
• Max. Allowable Voltage: 250VAC/110VDC
• Max. Allowable Power Force: From C(800VAC/240W), From A(1200VA/300W)
• UL, CUL,TUV recognized.
