Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

Components used in this project: 1x Arduino 101 3x Jumper wire 1x PIR sensor 1x LED light 1x USB cable Background: Arduino 101 is a microcontroller which can take in inputs and produce an output. In ...

In this DIY project tutorial, let's discuss what is turbidity, how to measure the turbidity of a liquid using Arduino and turbidity sensor.

In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

These sensors use a fresnel lens to collect the infrared light in the viewing area and transmit directly to the sensor. Although the solar lights used in this project had a PIR sensor built in, they ...

In this video tutorial, we will learn how a PIR Sensor works and how to use it with the Arduino Development Board for detecting motion.

To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate distance, and the Arduino ultrasonic sensor uses the ...
