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 ...
The MCP9800 is a digital CMOS silicon temperature sensor that provides an accurate digital temperature measurement. Data is converted from an internal diode temperature-sensing element to a digital ...
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 ...
