Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...
Abstract: Water level monitoring has long been an important task for farmers. Because weather conditions can change quickly, farmers have often checked that the water levels of their crops were ideal ...
Abstract: In this letter, we introduce a self-calibrating electrochemical sensor for water acetaminophen (ACT) detection. The sensor is built upon a graphite pencil lead (GPL) electrode modified with ...
This project pairs a pressure transducer with 2 microcontrollers which read and publish the water pressure periodically to an mqtt server. Why 2 microcontrollers? Because the pressure transducers I ...
Object anomaly detection is essential for industrial quality inspection, yet traditional single-sensor methods face critical limitations. They fail to capture the wide range of anomaly types, as ...
