Flame effect tip sensor for emergency power cutoff, using an ATtiny84 and ADXL335 3-axis accelerometer. Compatible with ADXL335 SparkFun breakout board if you don't want to solder surface mount parts.

To use the tip sensor, place it (at any orientation) and press the "set" button. Connect the power input to the load power and the output to the load device (such as solenoid valve). If the sensor changes orientation, it will disable the output power and deactivate the load device.
