The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

This dual-slope temperature sensor combines one negative-sloped and one positive-sloped temp sensor to create a V-shaped output, which can be used to compensate for a dual-temperature-coefficient ...

This circuit is a temperature sensing as well as alarm circuit. The circuit raises an alarm whenever the temperature crosses a certain limit. This circuit is a temperature sensing as well as alarm ...

The project aims to build a digital sensor thermometer based on TMP275which is 0.5°C accurate and uses 2-wire interface to connect to a microcontroller. The TMP275 is a serial output temperature ...

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...
