Description

The Grove - 2-Channel Inductive Sensor is based on Texas Instruments(TI) LDC1612, a 28-bit inductance to digital converter(LDC) for inductive sensing solutions. With multiple channels and support for remote sensing, the LDC1612 enables the performance and reliability benefits of inductive sensing to be realized at minimal cost and power. Inductance is an effect caused by the magnetic field of a current-carrying conductor acting back on the conductor. So by sensing the inductance, this sensor can detect the proximity of conductors especially metal nearby.

LDC1612 works based on measuring the parameters of the LC oscillator, formed by the PCB copper trace and the capacitor.

LDC1612 is able to measure the amount of energy it needs to provide to maintain the LC oscillation when a conductive object which is magnetically coupled with the LC oscillator approach. As the power loss of the oscillator circuit is proportional to the impedance of the conducting object, and the impedance value is affected by the distance of the object, it can then be used to determine the distance between the object and the LC oscillator. In this case, the PCB copper trace can be seen as an impedance sensor.
