How Do Motion Sensor Lights Work? There are three kinds of motion sensor lights: Active Sensors PIR (Passive Infrared Sensors) Dual Tech SensorsActive Sensors Tomographic Ultrasonic Microwave sensorsTomographic Sensors Tomographic sensors use radio waves to determine when something in the room has ...
Your eye is the principal light detector for any telescope. For most amateur astronomers, this is the only detector that they will ever need. You might want to take photographs of what you see, however, and you can do that with conventional lens and film cameras or with CCD devices/digital...
The motion detector emits radio energy into a room and monitors the reflection pattern. Circuit alarms are very effective for guarding the perimeter of a house, but they don't work so well inside a building. This is because the intruder's actions are highly unpredictable -- you don't know ...
