Integrating a shunt resistor and Hall-based current sensor into a single device helps simplify EV architectures and enhances ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...

A simple transistor circuit offers an effective solution to this problem. The I 2 C bus is highly vulnerable due to its design — both SCL and SDA “float” at high potential and are pulled low by the ...

This DIY seismograph project uses a sensitive vibration sensor to monitor tremors, including those too subtle for humans to feel. Want to detect earthquakes and other seismic events—from natural ...

Abstract: In particular primary electronics of sensor systems is strongly subject to deviations and degradations caused by environmental and manufacturing conditions. Current approaches cope with ...

The circuit makes it possible to obtain a high signal-to-noise ratio by effectively transferring signal charges accumulated in the photodiode to a small capacitance. We fabricated and tested a CMOS ...

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.
