This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

This circuit diagram illustrates a fire and smoke detection system using an Arduino UNO R4 WiFi, MQ2 smoke sensor, and a flame sensor (fire sensor). The Arduino is the central controller that receives ...

Constructor The DS18B20 library supports only the DS18B20, only one sensor per pin, no parasite mode, no Fahrenheit and no alarm functions. The only feature the class supports is the asynchronous ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging between 0.1 and 10 THz, could be leveraged to ...

Researchers have developed a flexible, transparent sensor that can detect temperature changes in real time without needing an ...

For those of us who aren’t blessed with a green thumb and who are perhaps a bit forgetful, plants can be surprisingly ...

TDK Corporation has expanded its MEMS inertial sensors portfolio with the Tronics AXO315T0, a high-temperature MEMS ...

Modern RC cars can be pretty darn fast. That’s fun and all, but it also makes it easy to crash them into things. This problem ...

A high sensitivity hollow fiber temperature sensor based on surface plasmon resonance (SPR) and liquid core is designed and analyzed using a finite element method. Toluene with high refractive index ...

A simple and compact sensor based on a cascaded fiber Bragg grating (FBG)/droplet-like fiber structure is proposed for simultaneous measurement of refractive index (RI) and temperature. The sensor can ...

As we all know, wearing a helmet is mandatory in most countries, including India while driving a vehicle, not just because of police fines but to save our own lives. Since it holds such an important ...
