Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching ...

The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...

Conventional wireless sensors typically rely on dielectric capacitors with inherently low capacitance, requiring operation at MHz frequencies. Here, the authors develop a wireless low-frequency ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...
