Description
The integrated circuit PCF8883 is a capacitive proximity switch that uses a patented (EDISEN) digital method to detect a change in capacitance on a remote sensing plate.
Features
- I I I I I I I I I I I I I I Dynamic proximity switch Digital processing method Adjustable sensitivity, can be made very high Adjustable response time Wide input capacitance range (10 pF to 60 pF) Automatic calibration A large distance (several meters) between the sensing plate and the IC is possible Open-drain output (P-type MOSFET, external load between pin and ground) Designed for battery powered.
