MULTIFUNCTIONAL PORTABLE ELECTRONIC DEVICE

摘要

A multifunctional portable electronic device (100) that easily allows a user to test dangerous fumes level is described. A power module (10) supplies a working voltage to a gas-sensing module (12) and an output voltage of the gas-sensing module is generated after sensing gas. A signal processor converts the output voltage of the gas-sensing module into a digital signal and calculates a corresponding gas concentration value that can be displayed on a display module (18).
