Fire pit ignition systems range from simple ones using a match to complex ones using electronics and an app. At one end of the spectrum are match-lit fire pits, with which you start the gas and light a match to get it started, and that's it. The next step up is a spark ignition system, which features a battery-operated sparker, so you just push a button to get the flame going. Moving up another notch is a flame-sensing fire pit, which has a spark ignition but also a flame sensor that can stop gas flow once flames die down for extra safety. At the far end of the spectrum are electronic ignition kits, which also are flame-sensing, and have an automated ignition process that can be controlled with a timer, a switch, a remote, or a phone app. These are the most expensive, and often require you to have electricity at your fire pit.
