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 ...

This digital thermometer circuit diagram uses a common 1N4148 diode as the temperature sensor. The temperature coefficient of the diode, -2 mV/°C is exploited for this application to create an ...

When they need to add temperature control to a project, many hackers reach for a K-type thermocouple for their high-temperature needs, or an integrated temperature-sensing IC when it doesn’t get that ...

The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

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, ...

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 ...

How an advanced material can become both p- and n-material based on temperature gradient. The process by which this material was discovered and enhanced. The possible applications of this device ...
