CAPACITIVE TOUCH SWITCH FOR AC APPLIANCES [DIY]

AC Touch Switch How to make CAPACITIVE TOUCH Switch for AC(220V) Appliances. In this video, we will see how to make a TOUCH SWITCH for AC appliance/load. This project is based around a capacitive touch sensor module TTP223. Components Required:- ) TTP 223 Module ) Resistor 1 K ) Transistor BC 547 ) Relay 5V ) AC wall Socket ) 5V Power Supply. ------------------------------------------- Schematic https://drive.google.com/file/d/1OVKDOmAXEAurbzNoUB_XOb-GIjLwY5AY/view?usp=sharing ------------------------------------------ after adding a metal plate, sensitivity can become very high. To reduce this sensitivity we can add a capacitor between Gnd and Pin 3 of IC TTP223. The value of capacitor will be anything between 3pF to 50pF. Sensitivity will decrease when the value of capacitor is increased and vice versa, when no capacitor is used then sensitivity will be at maximum. https://drive.google.com/file/d/10se0wFPMz8fBTLhH5xhtQN4YOKBKBWWk/view?usp=sharing --------------------------------------------- Hope you Like this Video Please LIKE Share SUBSCRIBE AND COMMENT hAVE A wONDERFul Day --------------------------------------------- and thanks to music creators.
