LCD Thermometer TCN77 Using AVR Microcontroller

Description The TC77 is a digital temperature sensor with a Serial Peripheral Interface. Temperature data is converted from the internal thermal sensing element and made available at anytime as a 13-bit two’s compliment digital word. Communication with the TC77 is accomplished via a SPI and MICROWIRE compatible interface. It has a 12-bit plus sign temperature resolution of 0.0625°C per Least Significant Bit ...

LCD Thermometer TCN75 Using ATTiny2313

Description This small thermometer board uses the Microchip TCN75 device. It is a cheaper clone of the LM75, it costs about 2,50 Euro. The TCN75 comes in a SO8 packaging. The TCN75 is a serially programmable temperature sensor. It has an output that is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Hysteresis is also programmable. Communication with ...

LCD Thermometer LM35 Using AT Mega8

Description The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55ºC to +150ºC and a accuracy of ±0.5ºC . The output voltage is 10mV/ºC . The output voltage is converted by the AD convertor of the AT Mega8. The temperature is displayed on an LCD module. In this example the thermometer has a rang ...

Temperature controlled fan using PWM microcontroller

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 enter the temperature limit through the keypad. The speed of the fan is adjusted by using the PWM. Circuit ...

SMT160 based Temperature indicator

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 -45deg to +150deg. The output duty cycle is D.C. = 0.320+0.00470 x t, ...

Thermometer with Clock using ATmega16

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 the proteus simulation code For more Detail: Thermometer with Clock using ATmega16 ...
