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 ...

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 ...

A split system heat pump's defrost sensor is used to detect ice buildup on the heat pump's outdoor coil. When ice builds up on the coil, it reduces the heat pump's ability to transfer heat, which can ...
