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 ...

It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

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 ...

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 ...

Abstract: Humidity significantly affects the accuracy and stability of smart gas sensors by altering response characteristics, introducing signal drift, and masking target gas signals, which poses ...

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 ...

The program creates a transparent overlay window on top of the screen that dims the image based on room lighting. Brightness is determined via ESP8266 with a connected photoresistor or Digispark ...
