Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

A floodlight camera combines a security camera with bright lighting in a single outdoor fixture, typically with Wi-Fi connectivity that lets you control it remotely from your phone. We've been ...

This is a breadboard friendly breakout board for the Maxim MAX30105 reflectance, particle, and pulse ox sensor. This library should work with other MAX3010x sensors including the MAX30102, MAX30101, ...

The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors. The DHT11 only returns ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

Abstract: In this tutorial, we discuss trade-offs in sensor system design. With examples from engineered systems in our laboratories, we address design considerations at the different system levels, ...
