Touch Sensor TTP223B, single channel, Capacitive Type Switch, use with arduino and relays module to turn ON your appliances. The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output lo..

TP4056 1A Li-Ion Battery Charging Board with Current ProtectionThe TP4056 constant current-voltage linear charging module for single-cell 3.7 V lithium batteries. During charging and discharging, it will continuously monitor the battery's voltage level and protects against overcharging and underchar..

  The touch sensor can detect the human touch by sensing the change of capacitance. 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 v..

Home automation capacitive touch sensor module uses the TTP224 integrated circuit, making it easy to add capacitive touch input to your project. It features 4 sensitive touch pads that make an ideal replacement for the old fashioned switches.Specifications:On-board 4-key TTP224 capacitive touch sens..

TTP229 - 16 Channel Capacitive Touch Sensor Module is easy to interface. It can be used along with a microcontroller or an arduino or even without one. When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the..
