Design of intelligent street light controller based on 51 microcontroller-EEWORLD

Collect

1. System Overview

The modules used in the system include AT89C51 microcontroller + LCD1602 display screen + ADC0832 + buttons + small lights.

The intelligent street light control system designed this time uses the AT89C51 microcontroller as the control core, and uses the LCD1602 display screen to display the digital voltage signal of the light intensity collected by the ADC. The light intensity threshold is set in the system program. It is in automatic mode by default. At this time, adjust The potentiometer can adjust the light intensity. Pressing the automatic button will switch to manual mode. At this time, pressing the manual on and manual off buttons can control the light on and off.

2. Simulation Overview

1. Use LCD1602 to display the light intensity voltage signal value.

2. Press the button to switch between manual and automatic modes. Press the manual on and manual off buttons to directly control the light on and off.

3. Adjust the potentiometer to simulate changes in light intensity.

3. Programming

Use Keil 51 for programming. When you open Proteus, the program is burned by default. If it is not burned, click on the AT89C51 microcontroller and import the program to run the system (the program file is a file with the suffix hex).
