Circuits Designed by Dave Johnson, P.E. :
Detects Flame in Water Heater  -  Design a device that detected whether the gas flame of the heater was off or on - whether it was heating water or not -  and convey that information to the bathroom.  With a readout in the bathroom, one would know if there were enough hot water to take a shower. A battery powered circuit would be best for his situation.  The flame detector circuit could be connected to a battery powered LED flasher circuit.  The actual LED could be mounted next to the thermostat, using the same wire pathway as the furnace thermostat wires, located nearby.  A remote flashing LED would change color from green to red, whenever the flame was on. . . .

Fire Alarm -  With the onset of summer, chances of fire accidents increase.  Such fire accidents can be prevented if timely alarms are available.  The circuit presented here warns the user against such fire...__ Electronics Projects for You

Flame Failure Monitor -  A minimum amount of hardware is needed to build a simple flame or fire failure monitor that enables you to monitor the status of the flame in a chamber/furnace.  Owing to its integrated alarm generator, the interface can be easily adapted for use with a wide range of light/heat sensors.  Here a readily available photo transistor __ Designed by T.K. Hareendran

Infrared Flame Sensor Switch -  the infrared detector switch is a very sensitive circuit that can be use to detect the presence of a flame, match, or a heat source, such as an iron or soldering iron.  up to 3 feet away an then activate a relay.  the heart of the infrared flame detector circuit is two tiny thermistor, as shown in figure 1.   __ Designed by Edy Jankovic

Op Amp Comparator & Reference IC provides miscropower Monitoring capability -  Design Notes 190__ Linear Technology/Analog Devices

Pyroelectric Fire Alarm -  Here is an ultra-sensitive fire sensor that exploits the direct piezoelectric property of an ordinary piezo element to detect fire.  The lead zirconate titanate crystals in the piezo element have the...__ Electronics Projects for You
