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 ...

A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

Abstract: This work presents a low-cost sensor and machine learning methods approach for plastic recognition in daily used objects. The sensor is a multi-spectral near-infrared sensor capable of ...

After testing hundreds of smart home devices, I rounded up the best options to get started with your smart home without breaking the bank.

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

Abstract: To address issues such as lost suitcases, incorrect retrieval, or overweight luggage during travel, this paper designs an automatic-following smart suitcase. The system consists of an STM32 ...

Belay is a sensor for FFF 3D printers for keeping a secondary extruder in sync with the primary extruder, avoiding error accumulation regardless of how long a print ...

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.
