Abstract:
A sensor circuit which operates under control of a controller circuit, the sensor circuit comprising:a transmitter; a receiver receiving signals produced by the transmitter in order to sense an event, the receiver comprising: a front end circuit which receives an input signal from a sensor element and amplifies the input signal to produce an amplified signal therefrom; a demodulator receiving the amplified signal and converting the amplified signal to a digital signal; an output circuit for producing an output signal in response to commands from the controller; an interface circuit coupled to the controller, wherein the interface circuit receives an operational parameter from the controller and relays the operational parameter to at least one of the transmitter, the output circuit, the demodulator and the front end circuit, and wherein the operational parameter is received by at least one of the transmitter, the output circuit, the demodulator and the front end circuit, and wherein the operation of at least one of the transmitter, the output circuit, the demodulator and the front end circuit is adjusted in response to receipt of the operational parameter; and wherein the front end circuit can also receive input signals from an external remote controller via the sensor element that convey operational parameters to the interface circuit.
