A system for generating a high DC voltage for a spark to ignite a flame in a combustion device, and a high AC voltage for a flame rod to sense a flame in the device, from a low voltage for combustion device control. The system may be an inexpensive mechanism.

Low cost high speed spark voltage and flame drive signal generator

A light detector having spaced electrodes preset by pins or a spacer within a sealed enclosure. The detector may have a MEMS structure that is separate from the sealing of the enclosure. Further, the detector may have a lens for the transmission of light onto the elements. The lens may be coated to affect the amount of light admitted into the enclosure. Light detectable by the sensor may be ultra-violet.
