Simple Proximity Sensor Circuit using a Single Opamp
Ultrasound sensor: learn about ultrasound sensors and systems features for different types of robots. They are also used to avoid obstacles, to navigate, and for what is known as map building. This article focuses on this technology, its benefits and limitations, how it is used and what the differences are between the sensors on offer
Robotic Sensing using - UC
Working principle of the proposed proximity detector circuit using IC 555. In the design a generation of rapid bursts of peak voltage pulses from the IC LM555 is implemented at a relatively lower frequency rate, which is transmitted via the infrared LED as jets of IR beams.
Sharp GP2Y0A02YK0F IR Distance Sensor (20-150 cm) Arduino
/27/2016If any object or other obstacles comes in front of the sensor, then the IR signals are get reflected and reach back to the receiver sensor. The IR receiver sensor then produces an output which is
What are Infrared Emitters, Receivers and Repeaters?
Time of Flight Sensor Technology Principle. Time-of-Flight (ToF) is a method for measuring the distance between a sensor and an object, based on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object.

We've extended our range of SmartLine active infrared beams with the SL-TNR series, wireless and hybrid
An application of infrared sensors for electronic white stick
Underwater distance measurement/Sensing. a 5-way split would be ideal for 5 beams in a flat plane. They do have a non-linear response and you will likely have to map values to the response of the sensor based on testing as IR attenuates pretty heavily in water, but this sensor is low cost and is incredibly easy to install and leverage.

2/30/2018Hello Friends, Is there any sensor to detect human presence . Am aware of PIR (Passive Infra Red) sensor , which would human motion but not the human presence . Another way is by using image processing technique.
Sensor to detect Human Presence - element14 - Arduino
An electronic walking stick for blinds. a new IR sensor based on the light intensity back-scattered from objects and able to measure distances of up to 1 m is described. The present
