💡 How does a sealed phototransistor float switch prevent false triggers?
To get reliable readings without mechanical contact, these units rely on light paths through clean fluid. They prove handy when your setup needs zero drift over long run times. - They isolate the sensing beam from abrasive sludge buildup - They stabilize voltage drops during rapid liquid shifts - They match well with microcontroller pins requiring steady input - They simplify wiring for compact brewing and mopping rigs
