This sensor uses I2C to communicate. And I2C instance is required to access to the sensor. The API provides simple distance measure, single swipe gesture detection, directional (left/right) swipe ...

Self-hosted, local only NVR and AI Computer Vision software. With features such as object detection, motion detection, face recognition and more, it gives you the power to keep an eye on your home, ...

This paper presents a robust motion-detector video sensor. It is intended to operate in surveillance applications for long periods of time with time-varying noise level. It makes use of the fact that ...

Zigbee is a protocol that has been around for quite a long time, and you can purchase many cheap smart sensors to incorporate into your own Zigbee network. Zigbee is its own network, meaning that it ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

This project uses an Arduino microcontroller to find and locate internal cable line faults. In many environments, electrical cables are buried rather than overhead, making it difficult to locate ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.
