Multipurpose Pedometer with Temperature Sensor
Multipurpose Pedometer with Temperature Sensor

Multipurpose Pedometer with Temperature Sensor

The design is comprised of MMA9553LR1 Freescale xtrinsic motion sensing platform that serves as the main component of the system. It monitors the step of an individual through the embedded pedometer of the system. It has a built-in temperature sensor that monitors either the surrounding temperature or the user's body temperature. It makes the user aware of the temperature so that they can provide the temperature limit preventing heatstroke and other related health problem. The LCD simply displays the data about the steps counting and temperature reading. The LC circuit serves as low pass filter while the discrete capacitors and resistors serves as stabilizers and pull-ups.

This design is applicable to some physical activity like jogging and running. It helps people monitor and ensure their activity. It is useful to people that undergo treatment requiring them to have daily exercises. It can still be modified in order to add more features.
