Free and easy circuit diagram of model  project for Student, Hobbyist and Educationist. All are DIY (Do it yourself) and EFY Projects for School.

Project using Sensor Circuit:

Clap Switch : Classical project for turning ON/OFF appliances by a sound of clap.

Automatic Street Light : Needs no manual operation for switching ON and OFF.

Electronic Letter Box : When letter is kept inside this letter box then a LED indicates its presence.

Rain Alarm : A tone is produced when wire is in contact with water. This circuit can also work for tank overflow indicator.

Heat Sensor : Simple, but sensitive Circuit for indication of temperature.

Temperature Sensor : For Detection of  Accurate Degree Centigrade by which you can make  many interesting projects.

Temperature Display using LCD: Digital Display Current Temperature using Microprocessor.

Automatic Fan Controller : Fan automatically starts rotating when temperature is hot. Speed is also controlled according to temperature. Easy Mini Projects.

Electronic Eye : It can be used as an automatic guest indicator at the door, if fitted on the bottom of the door entrance. Once it is installed at the door there is no need to install a call bell. It can also be used at homes or in banks as a burglar alarm.

Burglar Alarm : LDR is kept at such a place that when thief enters our house then a shadow will fall on the LDR.

Touch Switch : A tone is generated when any one touches sensor

Magnetic Switch : Switch ON a Circuit using a magnet. Hall effect sensor.

Fire Alarm : Simple Circuit for detection of fire. Simple and Mini
