A system including an assembly arranged in at least one of a seat and a steering wheel of a vehicle and a measurement circuit. The assembly includes a sensor and a heater arranged adjacent to the sensor. The measurement circuit is configured to output an excitation signal to the measurement circuit and the assembly and measure a resonant frequency of the measurement circuit and the assembly in response to the excitation signal. The measurement circuit is configured to determine a capacitance value based on the resonant frequency and determine whether a body part is in proximity to the sensor based on the capacitance value.
