Part Number: LDC1612EVM

Dear Ti community

I am working on the aforementioned evaluation board (LDC1612EVM) and was trying to see if i can hook up  an external loop of wire to it to detect the presence of a car or multiple cars? what value to i need to pay attention to ? what parameters do i need to adjust based on the wire inductance i am adding?

Please Advise ASAP

Thanks

    Hello Mohanad,

    Inductive sensing is not suitable for detecting cars. The sensing range is at most 200% of the coil's diameter, so an extremely large coil would be needed to detect a car even 25-50cm away from the target. The LDC devices cannot effectively drive coils this large. In addition, the variation in target shape, conductivity, and location would be a significant challenge.

    Instead, I recommend looking into ultrasonic sensing or mmwave sensing.

    Best Regards,
