please send to me a circuit diagram , explanation of that circuit diagarm, installation of that i.e how could we connect that to the fan, how can we tested this before using it in the main circuit of automatic temperature controlled fan .

And
also send to me explation of my attachement................. ....etc

Here is a circuit through which thespeed of a fan can be linearly controlledautomatically, dependingon the room temperature. The circuit ishighly efficient as it uses thyristors forpower control. Alternatively, the samecircuit can be used for automatic temperaturecontrolled AC power control.In this circuit, the temperature sensorused is an NTC thermistor, i.e. one havinga negative temperature coefficient. Thevalue of thermistor resistance at 25°C isabout 1 kilo-ohm.Op-amp A1 essentially works asI to V (current-to-voltage) c ....etc

ABSTRACT

As a part of curriculum prescribed for B. Tech degree of Engineering I have taken my practical summer training. The period of training was from May 18, 2009 to June 18, 2009.
The training report has been divided into 2 modules. First module concerns with the study and experiments performed on both Phase Change Materials (PCM) and Solar Radiation Chamber. The ....etc

INTRODUCTION
0-100°C electronic temperature controlled relay is a circuit using which the temperature can be controlled with the help of a LM35 temperature sensor.
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in˚ Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade ....etc

Abstract
The task of this project works with AC 230V, 50Hz power supply. The AC 230V converted into DC and the output of 12V DC source fed to the load via R1, R2, R3 and PT100 thermostat. The entire module performs by the logic gates of Thermostat and LDR. Particularly the module works whenever the instructions to be followed by the Industries according to the power sector rules. Similarly the work men of the industry as well as the superior’s related to the management of the plant followed by the above stated pa ....etc
