Overview: 

The ST01B touch sensor can detect changes in capacitance at a sensing point using the average capacitance value as a reference. It can sense capacitance changes through any non-conductive medium, so that the sensing module can be well isolated from water and dust. The ST01B has better immunity to interference and better consistency. This chip can work in low power consumption environment, when the power supply is 5v, the working current is 70ua, standby current is 5ua or less, also suitable for battery applications. 

Features:

● Single-channel sense chip with self-calibration.

● Can sense ‘key touch’ through any non-conductive medium.

● Adjustment of sensitivity by external capacitor.

● Open-Drain output.

● Operating voltage range: 2.5v~6.5v.

● Package: SOP8. 

Applications:

● Replacement Switch

● Human Sensor Detection

● human interface for toys and interactive games

● light switch

● LED dimming

● Replacement diaphragm switches

● sealed keypad panel
