Possible Application – Need advice

Sean Havanas

Would it possible to use the LDC1000 to detect the presence of a vehicle at a stop light? The application would replace the large coil they use now with a smaller coil, a micro, wireless transmitter and a battery. I read the height is about equal to the size of the coil. How large of a coil can the LDC1000 drive?

Hello,

Please refer to FAQ question2 here: http://e2e.ti.com/support/data_converters/inductive-sensing/f/938/t/295036.aspx#Q2

This is mostly a concern for small coil designs. For big ones, as in this application, it should not be a problem.

The coil diameter will rather be limited by detection range - if the coil is too small, it will be too far away from the car.
