TEMPERATURE LEVEL DETECTOR
When connected to a simple network of thermistor and resistors, the Alarm IC provides a portable solution for temperature control and supervision. The example hereafter uses an NTC thermistor. An audible alarm will sound when the threshold value at the comparator input is reached. A logic output is usable for starting either a fan or a heater depending upon the required temperature.
GAS SENSOR APPLICATION
The MC14600, used with a flammable gas sensor and a few added components, provides a r... |
