Arduino Digital Thermometer

This Digital Thermometer based on famous Arduino board and LM35DZ as temperature sensor. The sensor component has three pins, +5V, ground and a variable voltage output to indicate the temperature. This simple project wired the sensor output straight to the Arduino's analogue input 0. As display, it use two line LCD (a Displaytech 162B).

AVR Based Diode Temperature Meter

This is Multi channel diode temperature meter project with Microcontroller AVR AT90S2333 as main controller. It can be use to replace thermister temperature meter.

Front end of the temperature sensor and amplifier circuit consists of constant current. Approximately a constant current of 63µA sensor (diode) in the sink, a diode voltage drop of 3-fold amplification and A / D converter (10bit, 3.3V/fs) type. Drift in this block is the main cause of measurement error, the components must be selected as the low temperature drift.

Where an adjustment is not analog, EEPROM calibration parameters are calculated from the temperature to make sure that you store in it. The calibration process is required for proper equipment such as computer terminals instead of the driver. Some cases, ISP via cable (N81, 38.4kbps) has been to enter the calibration mode is turned on and connected.
