This project is a full-stack IoT application designed to monitor ambient temperature using an Arduino Uno R4 WiFi and a DHT11 temperature sensor. It operates in a local development environment and ...

Abstract: This paper presents the design and implementation of a low-cost, portable temperature and humidity monitoring system based on the Arduino Uno microcontroller, a DHT11 sensor, and ...

The Sharp GP2AP03VT00F Time-Of-Flight sensor seems to be a nice part for makers and roboticists, focusing on good short distance sensing where other parts sometimes have problems. Alas, Sharp seems to ...

Abstract: Automatic Smart Plant Watering System is a smarter solution that works on Arduino Uno, which can automatically operate for plant watering at optimal moisture conditions of soil. It checks ...

Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) ...

Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...
