The company has launched boards running Linux before, including the Yun and the Tian, yet it's typically competed more with ...

For some, Halloween is starting to rival Christmas for setting up elaborate holiday decorations. Homeowners now spend many hours─and sometimes dollars─creating ghoulish displays of lit pumpkins, ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

After introducing the 1 GHz RA8T2 MCU earlier this month, Renesas has recently expanded its RA8 lineup with the RA8D2 and RA8M2 groups of MCUs, where the ...

Wearable sweat biosensors enable the non-invasive, real-time monitoring of hormones. Here, we highlight the development and commercialization of a wearable technology that can measure hormone levels ...

Abstract: Human thermal comfort is highly influenced by environmental parameters such as temperature, relative humidity (RH), and air velocity in addition to personal factors. The available sensors to ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...

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 ...

Abstract: Flexible dual-mode sensors that are capable of simultaneously sensing temperature and strain exhibit huge prospects in applications such as health monitoring, human-computer interaction, and ...

Use a capacitive soil moisture sensor (it’s corrosion-resistant). If using a resistive type, power the sensor only during readings (use a transistor or MOSFET controlled by Arduino).
