It helps to control the home appliances using DTMF technology. DTMF Based Home Automation System Circuit: This is a simple and very useful circuit in our real life named DTMF controlled home appliances system.Here, the input voltage should be DC voltage to get the accurate output on LCD. This circuit measures the input voltage from 0V to 5V. Digital Voltmeter using 8051 Microcontroller: This is a simple digital voltmeter circuit designed using 8051 microcontroller.These are mainly used in environmental applications. Digital Temperature Sensor: The main principle of this circuit is to display the digital temperature value.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.Digital Tachometer using 8051 Microcontroller: Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec.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.
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.Bidirectional Visitor Counter using 8051: This Bidrectional Visitor Counter Circuit is helpful to count the number of persons entering or leaving a room and to display it on a screen.Automatic Railway Gate Controller with High Speed Alerting System: The main aim of this project is to operate and control the unmanned railway gate in the proper manner in order to avoid the accidents in the unmanned railway crossing.Auto Intensity Control of Street Lights: This is a simple circuit that automatically controls the intensity of street lights which is designed using microcontroller and LEDs.8 Channel Quiz Buzzer Circuit using Microcontroller: We built the circuit using a microcontroller which scans the input from push buttons and displays the corresponding number on a display device.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.This circuit can be mainly used in scoreboards. 2 Digit Up Down Counter: The main principle of this circuit is to increment the values on seven segment displays by pressing the button.
