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
