Abstract
The disclosure provides an emergency message transmission method and an electronic device implementing the method. The electronic device stores a reference voltage value and comprises a smoke assessing unit. The method includes steps: capturing air composition around the electronic device, assessing whether the air composition has changed, if the air composition has changed, detecting an electrical current of the smoke assessing unit, amplifying the electrical current and converting the amplified current to a voltage value, comparing the converted voltage value with the reference voltage value, judging whether the converted voltage value reaches the reference voltage value, and if the converted voltage value reaches the reference voltage value, outputting a signal including an emergency message.
