No. There are not machines that can detect motion sensors. You may be able to detect the sensor rays through special lighting, but the beams are normally invisible.
yes
Sensors are used to detect things, such as motion, light, or color.
Infrared laser sensors that can detect movement.
The homeguard may use various sensors such as motion sensors, pressure sensors, or heat sensors to detect the presence of a person. These sensors can detect movement or changes in weight or body heat, which help the homeguard identify the presence of a person in its vicinity.
Puffin crossings have special sensors built in which can detect when people is there.
One can detect heat sensors by searching their surroundings. Often, heat centers are located on ceilings in most rooms, and especially concentrated in areas such as the kitchen.
sensors can detect blood flow ,the movements of body and IR sensors can find the temperature of human body
Why are sensors helpful? That's my question.Well! Sensors help detect. If you have set a alarm light to get on when someone opens your pencil case that's sensor.
There are many different types of system sensors. These can detect anything from heat, fire, dust, and smoke. There are many different manufacturers as well.

No. Proximity sensors are generally used to detect objects, not people. Motion sensors use a different technology.
