Build a People Counter Using an ESP8266, NodeMCU and HC-SR501 PIR Motion Detector
Want to get an idea of how many people are coming and going in an area? Build your own people counter with an ESP8266 NODEMCU, HC-SR501 PIR Motion Sensor, Ubidots Cloud, and the Arduino IDE.
A people counter is a device that used to measure the number of people traversing an entrance, hallway, street corner, etc. If you need to know how many people exist in a space, this is your simple solution. Mostly used in retail stores, shopping malls, and smart office buildings, this counting technology has provided insight to how shoppers/employers behave.
How is the people counter application applicable to you (other than just being really cool technology)? Imagine you're the owner of a shop; this counter would alert you to daily visitors, the walking paths taken when inside, where they stop, and how long they linger at in a place. Wouldn't you like to know what materials gain the most attention; possibly being able to reposition products geographically to increase awareness to benefit your customers' needs and your bottom line?
In this guide in DZone, you will learn how to build your own home-made people counter using a NODEMCU and HC-SR501 PIR Motion Detector.
Also included are instructions for you newly collected data to be utilized via Ubidots, an application enablement platform.
