The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

The MAX471 is an older current sensor which can handle up to 50 Watt, with a maximum of 25 Volts or a current of 3 Amperes. It is officially not supported any more however there are still many for ...

Easy-to-use interface for configuring and reading radar data. Supports both single and multi-target detection modes. Works with Arduino-compatible board that has a separate hardware UART.

Abstract: Heart sound, pulse wave and respiration are simultaneously measured with single fiber Bragg grating(FBG) sensor. The FBG sensor is inscribed in optical fiber so that it is quite thinner than ...

Abstract: Microcomputers and medical devices with signal transceivers that operate on a specific radio display constitute the backbone of wireless sensor networks (WS Ns) that monitor environmental ...

Recently, I talked about how using your old Android phone as a security camera isn't the best approach for repurposing it, and discussed the possibility of using it as a smart home remote of sorts.

The system is built upon four foundational pillars: Autonomous Safety: Utilizing MQ-series gas sensors and flame detectors to provide real-time protection against fire and gas leaks through automated ...

Finally, eco-friendly music.
