A few simple components are all it takes to create an over-temperature alarm. The circuit in Figure 1 requires only an ordinary negative-temperature-coefficient (NTC) thermistor, two common ICs ...
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 multimeter is a measurement device most used by engineers and we use it in this temperature indicator circuit schematic. The temperature sensor is LM335 wich has a linear characteristic of 10mV / ...
Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.
Researchers have developed a 'fever alarm armband,' a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. The flexible organic components developed for ...
It combines a flexible amorphous silicon solar panel, piezoelectric speaker, temperature sensor, and power supply circuit created with organic components in a single flexible, wearable package.
