The Car Temperature Gauge is basically the same circuit as March’s project with some minor changes to the input circuit. This circuit will display the water temperature to 1 degree resolution.
It is often difficult to properly calibrate a temperature sensor since there is no suitable aid for doing so available. This article, which describes a temperature reference source, aims at putting this right. Since the source is made variable, the reference temperature may also be used for adjusting thermostats correctly…. Read more »
At the heart of this heat-sensitive switch is IC LM35 (IC1), which is a linear temperature sensor and linear temperature-to-voltage converter circuit. The converter provides accurately linear and directly proportional output signal in millivolts over the temperature range of 0°C to 155°C. It develops an output voltage of 10 mV… Read more »
High Accuracy Temperature Sensor Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, announced the MCP9808 silicon temperature sensor, which serves a broad range of applications by guaranteeing high accuracy of 0.5 degrees from -20 to +100 degrees Celsius, along with high temperature resolution of 12 bits… Read more »
Extended Temperature Oscillators Fox Electronics has expanded its line of XpressO configurable crystal oscillators with an extended temperature version of its 3.3 V HCMOS oscillator in a compact 3.2 mm x 2.5 mm package. Part of the FXO-HC33 series, the new oscillator can withstand temperatures from -40°C to +85°C, while… Read more »
As described in the previously article about the AD7711, this family of ADCs device are designed specifically for low frequency, high accuracy industrial transducer applications. This device has an on-chip self calibration to compensate for temperature drift and reference inaccuracy. It is known about the possibilities to calibrate the ADC… Read more »
