Hackathon winners cleverly avoid the billions of IoT sensor truck rolls needed to help visually impaired people navigate by using sounds instead of sensors. The Internet of Thing’s dirty little secret ...

If you need to measure a distance, it is tempting to reach for the ubiquitous ultrasonic module like an HC-SR04. These work well, and they are reasonably easy to use. However, they aren’t without ...

Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually ...

Researchers designed an IoT network using sound and motion sensors that estimates public space utilization. The ideas can be applied to other IoT sensor networks. Sensor Fusion for Public Space ...

The sensors in your smart device are a big part of what make it, well, smart. Sensors allow our devices to understand context— they tell phones where they are in space and how we’re using them. This ...

Does anyone know where I can find a sound sensor that would pick up a pitch that I can program it to detect? When this sound is detected I would then like to send an email alert to a specified address ...

At Build this year, Satya Nadella promised it would be "the most powerful sensor with the least amount of noise", and with an ultra-wide field of view. It's small enough and low-power enough to use in ...
