Technology is ubiquitous in our world today. From our smartphones to our cars, we rely on technology to simplify our lives. One little piece of tech you may never have heard of is the IR sensor module. This little device is a great boon and assist us in multiple ways.
Before we start connecting and using an IR sensor module in a project, we should know how it works. IR sensor module uses invisible light known as Infrared light to detect motion and objects. Our eyes are unable to perceive infrared light, but the IR sensor is capable of doing so.
Now that we understand what an IR sensor module is, lets check how to interface and use one in a project. IR Sensor module is very easy to connect. All you have to do is to wire up the power and ground to some micro controller and Arduino Uno board. Then navigate to the IR sensor module and program it to detect motion or objects. This can be done using coding languages such as C++ or Python.
IR sensor modules are not only motion/object detectors. Automation is another area where they are being utilized. For example, IR sensor modules are used to automatically open the door when someone approaches it. They also serve as security systems for locating intruders. Automation stands with an ocean of projects where IR sensor modules can be used.
As with all technology, IR sensor modules can occasionally have issues. Interference from other sources of infrared light is a common problem. If that is the case, you can change the sensitivity of the IR sensor module or move its position. A loose connection may also be an issue. Check that you have all your wires connected properly to the microcontroller or Arduino board.
If you want to enhance your projects further, consider integrating advanced functionality into your IR sensor module. You are known to add a timer that determines how long it will detect motion or objects. Or use a distance sensor to view further afield. IR sensor modules can spice up a lot of your projects in interesting ways.
