How can sensors be used to detect objects?

Ultrasonic sensors use sound waves to detect objects. Most ultrasonic sensors detect objects and measure distance by listening for the return echo of an emitted sound wave reflecting off of a target or background condition.

Can IR sensor detect humans?

The Passive Infrared (PIR) sensor is used to detect the presence of human. But this detects the human only if they are in motion.

Which sensors are used to identify objects for pick and place purpose?

The sensors used for detecting and classifying objects are using an RFID system (Radio Frequency Identification) because each RFID tag has a unique code and different from another. STM32VLDISCOVERY was used as a main controller for displacement movement of objects in the robot and classifying objects simultaneously.

What is a human body sensor?

Body sensors are considered as a highly advanced data acquisition and information gathering system. The biophysical/biochemical mechanisms governing processing of gathered data result in involuntary mechanical movements like heart rate control or voluntary artistic movements such as in painting.

How can we detect human movement?

Among them, in this paper, we focus on pyroelectric infrared (PIR) sensors as sensing systems to detect human body movement in an indoor environment. PIR sensors are well known and have been widely used as a simple, but powerful presence trigger for alarms, such as surveillance systems and automatic lighting control.

What is sensors in human body?

Humans have 5 main senses: vision, hearing, smell, touch and taste. Our sensors include the eyes, ears, nose, skin and tongue. Additional sensors include temperature sensors, body position sensors, balance sensors and blood acidity sensors.

How can we detect humans?

Modern technologies proposed or deployed for human sensing include:

  1. Acoustic sensors.
  2. Image recognition of human shapes.
  3. Infrared detectors.
  4. Pressure-sensitive floor tiles.
  5. Radar.
  6. Chemical sensors.
  7. Detection of the mobile phone, computer, Bluetooth, or Wi-Fi signals of a device assumed to be in the possession of a person.
