A team of researchers from Koç University in Turkey has developed a tiny sensor that can monitor the freshness of protein-rich foods like meat, chicken, and fish in real time and send the data to your ...

Abstract: Gas sensors are increasingly being utilized in food spoilage detection due to their high sensitivity, miniaturization, and low power consumption. These sensors play a crucial role in ...

Scientists have created an edible sensor that can detect whether your frozen food has thawed and then been refrozen – and is therefore potentially contaminated. The proof-of-concept sensor, created at ...

Researchers at the University of São Paulo (USP) in Brazil have developed a kraft paper-based electrochemical sensor that can detect traces of pesticides in fruit and vegetables in real time when ...

This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...
