This Thermometer used LM35 precision centigrade temperature sensor from National Semiconductors which has an analog output voltage. It has a range of -55ยบC to +150ยบC and a accuracy of ยฑ0.5ยบC . The output voltage is 10mV/ยบC . 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 range of 0ยบC to 40ยบC and a resolution of 0.5ยบC. If you want to have a readout in Fahrenheit you can use the LM34.[more]
This project is a 3-digit digital thermometer easy to build for beginner or hobbyits.PIC16F628 used to read digital value of temperature from a DS1820 sensor.All 7-segments drived by power logic 8-bit shift register TPIC6B595 with open collector output. For the 7-segment need 12V volt to drive because it have 3 LED per one segment.All segment no need to scan display. Source code programming with CCS C Compiler availible. [more]
This is a digital clock and temperature display which is alernate display between time and temperature.Here are some features:
- Display time 24-hour format. 00:00 - 23:00
- Use DS1307 RTC with 3V betterry back-up.
- 1 channel temperature sensor(DS1820)
- measures temperatures from -55 to + 125 degree Celsius.
- Temperature accuracy 0.5 ‘C
- software compiled with CCS C compiler V 3.222
Each encoder channel has a dedicated microcontroller, this feature gives it a high speed encoder tracking ability.It will track at up to 30 KHz ! All four channels are controlled by a main chip. The main chip takes care of calculating values for the LCD display.The main controller uses 32 bit counters so there are no practical limits for it’s use.[more]
The Nokia 6100 display is able to display 130 by 130 pixels with 8-bit or 12-bit color (4096 colors) and it has a LED backlight. It is controlled with Serial Peripheral Interface Bus (SPI). That means it needs only 3 wires for controlling it : Serial data(SDATA) ,Serial clock(SCLK) ,Chip select (CS).[more]
