![]() ![]() Based on these sensors, controller detects the traffic and controls the traffic system. All these sensors are interfaced to the microcontroller. We have to arrange one IR sensor for each road these sensors always sense the traffic on that particular road. Density Based Traffic Signal System using Microcontroller: In this system, we use IR sensors to measure the traffic density.It can be used at homes, mobile places like cars to keep a track of the temperature. This circuit works on analog to digital conversion principle. ![]() Celsius Scale Thermometer using AT89C51: This Celsius Scale Thermometer circuit is designed using at89c51 and lm35.This circuit can be mainly used for indication purposes. Bipolar LED Driver Circuit: This bipolar LED driver circuit is very useful at the places where flashing of light is required, as in beacon flashing.This circuit works on the principle of IR communication. 5 Channel IR Remote Control System using Microcontroller: This article is aimed to design and demonstrate a simple 5 channel remote control system to drive five loads. ![]()
