This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

Abstract: This paper introduces a novel screen-printed temperature sensor with a conductive ink made of reduced Graphene Oxide (GO) and Kish Graphite (rGO/KG). KG, an industrial waste, was recovered ...

Remember Sidewalk, Amazon’s low-power “neighborhood” network that incorporates Echo speakers; Ring sensors, cameras, and video doorbells; and some third-party devices–such as Level smart locks and ...

Abstract: A Complementary Metal Oxide Semiconductor (CMOS) temperature sensor using auto-zero technology was designed based on the CMOS 55 nm process. The sensor consists of a temperature detection ...

Scientists in Japan have created a new metal catalyst that turns carbon dioxide and hydrogen into liquid methanol at room temperature. In early tests the catalyst converts every carbon atom it ...
