Abstract
A method of determining a parameter includes providing a sensor that provides a sensor analog voltage. A peak detecting circuit for detecting a peak voltage in the sensor analog voltage is also provided. The sensor analog voltage is provided to the peak detecting circuit, and the peak voltage is detected. A microprocessor is provided in sleep mode and is awakened once the circuit detects the peak voltage. The microprocessor samples and records the peak voltage and the microprocessor goes back to sleep.
