Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane. For [Jianj… ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

The same transducer is used as the receiver. An on-chip LDO allows for connection directly to the automotive battery for dc power. A complete ultrasonic sensor module is shown in Figure 2.

An evaluation kit from TDK showcases its USSM1.0 PLUS-FS ultrasonic sensor module for designs requiring obstacle detection and distance measurement. Aspencore network. ... The starter kit comprises a ...

Ultrasonic sensors can measure distance without contact. can measure distance without contact. They bridge the gap between proximity and photoelectric sensing. They possess a longer sensing ...

A single sheet placed between the emitter receiver pair attenuates the ultrasonic signal. For example, a single metal foil sheet can reduce audio intensity up to 80% at the receiver.

This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

Ultrasonic sensors are already widely used in automotive applications and a variety of industrial applications. Now, though, new potential applications are being discovered in the home-automation ...

The receiver also holds promise beyond the human body. Its ability to function underwater makes it suitable for long-term deployment in marine sensors and autonomous underwater drones, where wired ...

GRAZ, Austria, December 19, 2024--USound, the global leader in MEMS loudspeakers, today announced the showcase of its fully developed ultrasonic sensing module at CES 2025 in Las Vegas, Nevada.

Fraunhofer researchers will present their development at the SENSOR+TEST measurement fair in Nürnberg, May 30 to June 1, 2017. Technical systems must be regularly checked for defects, such as cracks.
