How Do You Pass A Motion Sensor Light?
Light-based motion sensors emit brief pulses of invisible microwave radiation and then measure the time it takes for the pulses to reflect back to the sensor. This return time provides the sensor with a rough idea of the geometry of the space it is monitoring. If the return time changes drastically, this indicates to the sensor that the geometry of the space has been changed — by the body of an intruder passing through, for instance. Though no method is foolproof, you can take steps to increase your odds of slipping through the sensor’s field of view without triggering it. Soak the black bedsheet in water. Wring until it’s damp but not dripping. Place the damp black sheet over your body, cutting eye holes as necessary. Secure sheet so that it fits the body snugly, with no stray ends trailing behind it. The color black and the chemical H2O are both excellent absorbers of microwave radiation, and they will diminish the amount of microwave light you reflect back to the sensor. Walk very
