CJMCU-0401 4-bit Button Capacitive Touch Proximity Sensor keyboard With Self-locking



CJMCU-0401 4-bit Capacitive Touch IC Sensor Button Keyboard Sensor With Self-locking Function For Arduino

Product description:



CJMCU_0401 is a leisurely touch IC using capacitive sensing principle design, the stability of the sensor can be applied to a variety of different electronic products, the panel medium can be completely insulated material, designed to replace the traditional mechanical switch structure or ordinary button design. Provides 4 touch inputs and 4 direct output pins, and 4 LED indicators.







Product characteristics:



Working voltage: 2.0V - 5.5V



Maximum power consumption of 11.5uA, low power mode only 4uA (both 3V and no load)



The external configuration pin is set to multiple modes



High reliability, chip built-in jitter circuit, which can effectively prevent the external noise interference caused by misoperation



Can be used in glass, ceramics, plastics and other dielectric surface



With auto calibration function, the system recalibration period is about 4 Sec when no button is touched.
