Design of a portable ammonia detector for supporting gas safety fields

摘要

In this paper, we proposed a design of the field-supported portable ammonia detector. Ammonia gases are toxic gases so they stimulate nose and throat and cause many diseases. So, we designed the detector for detecting the ammonia gases more safely. The structure of this detector is a detachable structure. Its detection part and display part can be separated. It has algorithms of an accuracy improvement using least square method and Neville interpolation. Also, it can use Bluetooth communication. Bluetooth communication is used when the display part and detection part is separated. So, it can check, adjust, and transmit the measured data when it is separated. Furthermore, the measured data of concentration of ammonia gases can be transmitted to the smart devices using Bluetooth communication and can be manage the data in the smart devices.
