碩士 === 國立勤益科技大學 === 資訊工程系 === 103 === In this thesis, we design an indoor temperature monitoring system to prevent fire accidents. The system is equipped with a multi-element thermopile for measuring the temperature of a given plane, a RGB LED of which colors indicate the temperature range and a ZigBee-RS232 module that transmits the temperature values to be displayed as different colors on a PC screen. The buzzer in the system is activated when the temperature reaches the threshold. The measuring information will be sent to Google Drive and displayed on the web and informed by Android App. The indoor temperature monitoring system will send a text message and E-mail to the users when the threshold temperature reached. The effective detection range of the system is from –20℃ to 100℃ or 0℃ to 60℃ and the field of view is 56⁰X8⁰ or 30⁰X22⁰. The temperature measurement error is confined to ±1℃. The simulation results of the system are proved effective for fire accident prevention.
