This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

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 ...

With CPUs and chip sets running at clock speeds that were once thought of only in terms of UHF and microwave communications frequencies, heat generation is a problem for PC-system designers. The ...

Microchip has announced 10 automotive-grade multi-channel temperature monitoring ICs that use external diodes, transistors or substrate diodes (MCU or other die) as sensors. Called the MCP998x family, ...

To understand the concept of a remote temperature sensor and how it differs from a local temperature sensor, it’s best to first review some basics of temperature-sensor ICs. A silicon ...

For temperature sensing from 1.8V supplies, Microchip has introduced the EMC181x family of temperature monitors. Working with on on-chip sensor, plus various combination of external diode-connected ...
