This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

Comparison of Capacitive with Induction Sensors. Capacitive sensing involves charging up plates, so it is somewhat slower than inductive: 10 to 50 Hz, with a sensing distance from 3 to 60 mm.

Migatron Corp., the leading USA ultrasonic sensor manufacturer has recently announced a two new sensor models aimed at proximity detection and displacement measurement tasks for production line ...

Ultrasonic Range Sensors Bring Precision to Social-Distance Monitoring and Contact Tracing Sept. 2, 2020 Ensuring safe social distancing is one piece of the puzzle for workers in the COVID-19 age.

Two independent RC networks, the adjustable reference network R4 with C2 and the sensor network R3 with CS (sensor pad capacitance), act to delay the pulses along different paths.

The low-frequency ultrasound sensor, with a surface component of around 10 x 10 mm 2 and a 5 MHz vibration frequency, is used for abdominal imaging. When measuring the low-frequency sensor, a 5x ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, ... The infrared receiver IR1 is only sensitive to light modulated with a specific (38kHz) carrier frequency, so it ...
