I want to detect objects between two closing doors with the AD7747.
The Sensor consists of two pair of electrodes, which are one after the other. One pair of electrodes will sit on the top closing area and the other pair on the bottom closing area of the door.
I want to use the AD 7747 with the differential mode. In theory, there will be capacitance changes, when there is an object converging to one of the two electrodes.
My questions are:
Thank you very much for your help!!
this is same as AD7747 Differential Mode
