Abstract
A system for automatically igniting a gas lamp by sensing the presence of a flame according to one embodiment of the present invention may include an igniter, power source, relay, valve controller, pulse-width modulator, and microcontrol unit. The microcontrol unit is connected to the igniter, the power source, the valve controller, the relay, and the pulse-width modulator. The microcontrol unit uses the pulse-width modulator to calibrate a total power supply to the igniter and determines the presence of a flame by sensing an electrical resistance of the igniter to the total power supply. The microcontrol unit also controls the amount of electricity supplied to the igniter through the relay and adjusts the amount of combustible fluid supplied to the igniter through the valve controller to automatically ignite the gas lamp.
