This project uses IC LM35 as a sensor for detecting accurate centigrade temperature. Linearity defines how well over a range of temperature a sensor’s output consistently changes. Unlike thermistor, Linearity of a precision IC Sensors are very good of 0.5°C accuracy and has wide temperature range. its output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 is rated to operate over a -55° to +150°C temperature range.It draws only 60 µA from its supply, it has very low self-heating, less than 0.1°C in still air. LM35 Operates from 4 to 30 volts. Output of IC is 10mv/degree centigrade for eg if the output of sensor is 280 mV then temperature is 28 degree C. so by using a Digital multimeter we can easily calculate the degree temperature. For trigger point you should set the voltage of pin 2 of IC 741 by using preset or potentiometer. Our aim of this project is not to construct a thermometer but to activate or deactivate a device at a particular m...

If you want will build a Small stereo amplifier project for computer. This projects is best for you. Before read detail of they we should read mono model on This is Super Small Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little. This is Super Small Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little. And still can use force against large-sized get comfortablely ( I has tried already ) besides it still use volt power supply very wide be about 1.5V arrive at 15V as well. Regard as IC TDA7052 be worthwhile very much. For you who want to try build this circuit. I has model PCB give a friend tests to see with. Request have fun the circuit amplifies miniature please.
