Design of Automobile Detection of Oil Quantity Alarm
Abstract: This paper takes AT89C51 MCU as the core component, and the capacitance liquid level sensor, ADC0808 converter and LED digital tubes as the peripheral circuit to realize the design of oil quantity alarm detection. The designed Alarm can display the surplus oil quantity digitized and when the residual oil volume is out of the preset range the alarm can give off alarming signals in different tones with LED lights lighting. The whole design uses Proteus software to complete the simulation, and the results are expected.
