Occupancy sensor; What do they do?

Occupancy sensor, Occ sensor, motion sensor. They have various names but they all do basically the same function.

So Many Infrared Sensors to Choose From

While there are different sensor technologies (infrared, ultra sonic, and dual technology) today's post is about which applications are not suited to the PIR, or infrared sensor and how to choose an Infrared Sensor.

Do Occupancy Sensors Save Big Money?

I have written in the past about which sensors are for various applications, however a common question I hear is "how much electricity do they save?". In this article I will run through a common scenario and show the benefits of adding them to your lighting system.

Infrared, Ultrasonic, Dual Technology, which do I choose?

In a previous post "Motion Sensors 101", I listed the functions of motion sensors.
