The design parameters affecting performance are improved, helping Microdul meet the needs of their customers when it comes to proximity sensors.
The Challenge: Reliability Of Electrostatic Proximity Sensors In A Difficult Environment
Microdul produces proximity sensor chips that can be used with remote sensing plates. Changes in plate capacitance are detected by a digital auto-calibrating algorithm. An approaching human finger typically causes a switching operation.
The capacitive switch can be used for many non-contact applications. The main challenge is to develop a sensor which can reliably distinguish between intentional switching operation and environmental interference.
