1. An arm-based pedometer comprising:
- an article to be worn on an arm of a user, the article having a first surface and a second surface;
a processor;
a powering source;
a short range wireless transceiver for transmitting data from the article;
an accelerometer; and
an optical sensor communicably coupled to the processor for generating a signal corresponding to the heart rate of the user, the optical sensor comprises a light-to-voltage photodetector capable of transmitting a digital signal, and one or more light emitting diodes capable of radiating green light in a range between 500 to 570 nanometers;
wherein the processor is configured to generate a real-time heart rate from a signal from the optical sensor, and to process a signal from the accelerometer in a pedometer function to determine distance traveled by the user.

Abstract
A monitoring device with a pedometer function preferably comprises an article, an optical sensor, an accelerometer and processor. The optical sensor preferably comprises a photodetector and a plurality of light emitting diodes. A sensor signal from the optical sensor is processed with a filtered accelerometer output signal from the accelerometer to generate a pedometer function.
