The Anti sleep alarm works on the principle of electronic balance and does not interfere with normal movements in the car. The alarm sounds only when the driver's head falls forward in drowsiness, simple but effective.
How does it work
Turn the power on, and wear it on right or left ear. It emitts "Bi-Bi-" alarm when driver tends to fall asleep with his head lowered; there is no sounds emitted when driver keeps normal driving status with eyes looking forward.
