Laser Distance Sensors; Infrared Distance Sensors; Time of Flight (ToF) Sensors; Time-of-Flight (ToF) sensor is a very effective sensor for range-finding and distance sensing as it emits light rather ...

On its own, the ultrasonic distance sensor is only accurate to about 5%. By incorporating a temperature sensor, [Neil] was able to nail down the accuracy of his sensor to about 1%.

Like the Sharp it’s more of a proximity sensor than a distance sensor. Adafruit’s testers found it worked best at around 10 mm to around 150 mm, or around 7.5″ and under.

Sensor technology is also used frequently in medical devices. Input sensors such as myo-electrodes are used in prosthetic technology. Myo-electrodes detect electrical signal from a patient’s muscle ...

Ultrasonic sensors operate by transmitting sound waves that reflect from the liquid surface and are obtained by the sensor. The sensor measures the time interval between the transmitted and received ...

The formula for this calculation is D = ½ T x C (where D is the distance, T is the time, and C is the speed of sound ~ 343 meters/second). For example, if a scientist set up an ultrasonic sensor aimed ...
