| Abstract: | According to the principle of air pressure altitude measurement, the composition and working principle of mini UAV altitude measurement system which is based on MPX4115 sensor and C8051F020 single Microcontroller Chip are introduced. The circuit design of measurement system is also demonstrated in detail. In order to ensure measurement accuracy, the pressure instrument is used to identify MPX4115 sensor. The mathematics formula of altitude and atmospheric pressure is imitated, and the compute program is obtained. It is solved effectively that the lacking of calculation of C8051F020 single Microcontroller Chip. The system has a lot of advantage such as small size, low power consumption, high speed, simple and reliable circuit, and so on. |
