In this video, I'm making a carbon monoxide monitor for my home using an MQ7 carbon monoxide sensor, a DHT11 temperature and humidity sensor, and a NodeMCU microcontroller board. This sensor is ...

Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...

Abstract: In this article, we present the design of an on-chip polarization image sensor with a hardware root of trust (RoT) for trustworthy sensing provided by an interconnection metal-wire-grid (MWG ...

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove - Light Sensor, this ...

I wanted to build a sensor to determine the state of my garage door—open or closed—and send that state to Home Assistant so I can display the status in a dashboard and build automation from it (e.g.
