My final version of the 3d printer wireless safety shutoff system. Designed to cut AC power in event of over-temp or smoke. This version uses a logic-level mosfet to get full range from the hacked wireless remote and is designed to be etched on a single-sided 70*100mm board and use cheap, easily obtainable components.
Attached are board layouts for etching, Eagle schematics and board files, png of schematic and board, Arduino sketch for editing/flashing, bill of materials and gcode for printing cover to attach to Anet A8.
Detailed look at schematic and demonstration of it working. Please feel free to improve and share.
Added a second Arduino sketch thaat incorporates a delay to allow the MQ2 smoke sensors to warm up in order to prevent false triggers when starting from cold.
Good luck All.
As usual, please do not rely on it for printing unattended.
