Abstract: This study presents a passive and chipless humidity sensor to monitor relative humidity (RH) continuously. The sensor is constructed on kapton substrates, a C-shaped resonator integrated ...

The Texas Instruments CC1101 is a very versatile, high quality and cheap transceiver, supporting a wide range of frequencies and modulations. Ready-to-use CC1101 modules are as cheap as 5.00€ and at ...

I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless control to Arduino or ESP8266 projects. In this video, I’ll walk you through ...

Abstract: This work presents a compact smartphone-integrated relative humidity (RH) sensor based on intensity modulation using agarose-coated polymer optical fibers (POFs). The sensing architecture ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Installing a smart water sensor can save you a lot of money and hassle. The top leak detectors we've tested immediately alert you to issues and even shut off your home's water supply. I’ve been ...
