Yesterday, I wrote about a 2-year-old open-source hardware ESP32-based DAB+ receiver project, but it turns out there’s also a digital radio project for the Raspberry Pi that was released about three ...

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

Abstract: To address the issues of low efficiency and frequent manual intervention in traditional greenhouse environmental monitoring and management, a multi-sensor smart greenhouse environment ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

pH sensors typically consist of a glass electrode that produces a voltage proportional to the hydrogen ion activity (pH level) in a solution. This voltage signal then needs to be interpreted by an ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

Although the Raspberry Pi started out as a way for kids to learn to code, it has turned into so much more since its invention in 2012. At first, the Pi was something of a simplified computer, and ...

A Raspberry Pi 5 has the ability to capture video via attached cameras and access the Internet using wired and wireless protocols, all while driving a pair of personal computer displays. However, if ...
