Using this measurement and the speed of sound in air, you can make your program calculate the object's distance in centimeters, inches, feet, etc. The controller uses a variable to store how long the high signal from the Ping sensor lasted. Then, at the same time the Ping sensor chirps its 40 kHz tone, it sends a high signal to the controller. Most common sizes ? Then, the Ping sensor waits a short period of time, enough for the controller to start a elapsed time counter. L change in length due to a force and L0 the original length before the force was applied Can be caused by tension or compression forces 28 Sensors and Transducers Strain gages Strain and Stress Strain? Therefore, the space between the two contacts is made narrow and long for low cell resistance at moderate light levels. These thin films have a high sheet resistance. Thin film devices made by depositing a layer of a photoconductive material on a ceramic substrate. Signal current from the detector can be varied over a wide range by adjusting the applied voltage.
