Wireless sensors scattered throughout a building can monitor everything from humidity and temperature to air quality and light levels. This seems like a good idea–until you consider the hassle and ...

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 ...

The Type LM35 temperature sensor from National Semiconductor is very popular for two reasons: it produces an output voltage that is directly proportional to the measured temperature in degrees Celsius ...

Using a home's electrical wiring as a giant copper antenna allows for wireless sensors that can communicate over a whole house and run for decades on a single watch battery. The device could be used ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

None of the dimensions in Monday's diagram match the earlier diagram "leaks" from April 12, nor is the Touch ID sensor located on the rear. For comparison, the iPhone 7 Plus has a smaller bezel at ...

Researchers have developed a sensor array design technology inspired by the human auditory system. By mimicking the human ear's ability to distinguish sounds through tonotopy, this innovative sensor ...
