Sensitivity can adjust by the capacitance(0~50pF). Technical Article Introduction to Capacitive Touch Sensing May 24, 2016 by Robert Keim In this article, we will take a detailed (but not too detailed) look at the electrical principles that allow us to detect the presence of a human finger using little more than a capacitor. The touching … Sensitivity can adjust by the capacitance(0~50pF) outside. When triggered the module's output will switch from its idle low state to high (default operation). The sensitivity adjustment must according to the practical application on PCB. This touch detection IC is designed for replacing traditional direct … After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is … The TTP223-BA6/TTP223N-BA6 offers some methods for adjusting the sensitivity outside. For example, if you needed the touch switch to work through glass or acrylic you will be needed to adjust the sensitivity based on … Low power consumptionand wide operating voltage are the contact key features for DC or AC application. Otherwise it can decrease sensitivity. Using a larger elect rode size can increase sensitivity. Input Voltage : 2 Volt – 5.5 Volts DC. TTP223 Touch Sensor Module is based on the dedicated TTP223 touch sensor IC which offers 1 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. TTP223 Touch Key Module – 2Pcs ₹ 69.00. The TTP223 is a touch pad detector IC which offers 1 touch key. TTP223 Capacitive Touch Sensor Module The TTP223 is a touch pad detector IC replicating a single tactile button. FEATURES Operating volta It consumes very low power and the operating voltage is only between 2.0V~5.5V. 1-1 by the electrode size Under other conditions are fixed. The value of Cs use smaller, then the sensitivity will be better. The TTP223-BA6 offers some methods for adjusting the sensitivity outside. The capacitance Cs can be used to adjust the sensitivity. Sensitivity can adjust by adding a capacitance, the value of capacitor ranges from 0 to 50 pf, where 0pf gives the full sensitivity and 50pf will gives the lowest sensitivity. Using a larger electrode size can increase sensitivity. The sensitivity of TTP223N is better than TTP223’s. The TTP223 is … 1-1 by the electrode size Under other conditions are fixed.
