Building Arduino projects with multiple sensors can unlock powerful environmental monitoring, automation, and IoT applications. From DHT11 temperature sensors to motion, gas, and light detectors, ...

Recent Arduino projects showcase increasingly sophisticated multi-sensor integration, from multiplexers solving I²C address conflicts to interactive hubs with multiple modes. Developers are pairing ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

UV (ultraviolet) sensors of all sorts have been an interest of mine. They become interesting when you find the diversity of real-world practical applications. While searching for affordable UV light ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...
