This project gives you a simple temperature controlled fan. If the difference between real temperature and the user temperature is high then the fan will run at full speed and if the difference is low then the fan will rotate at slow speed. The speed of the fan varies with the temperature. The user can […]

There are lot of temperature sensors both with analog & digital outputs. This project gives you an another temperature indicator which has been done with a digital sensor SMT160. Although it is a digital sensor it does not gives out the temperature directly. The output is duty cycled modulated. The sensor can measure temperature from

LM35 can measure temperatures from -55deg to 150deg and we need negative supply voltage for measuring this negative temperature. This circuit eliminates the negative voltage power supply and this project can measure the negative temperature Download the protesu file to simulate the project on your desktop Bascom Code $regfile = “m16def.dat” $crystal = 1000000 Config

This project will display the temperature and time over the LCD display. LM35 is used to sense the temperature and the analog out of the LM35 is converted to digital by using the inbuilt ADC on the ATmega16 chip. An software clock is generated and the Time is also display. Download the Bascom code and

I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree C, which can be interfaced with microcontroller over two-wire serial i2c bus. It has operating voltage range from 2.7 to 5.5v. I’m operating
