Build a People Counter Using an ESP8266, NodeMCU and HC-SR501 PIR Motion Detector

Posted by Envistia Mall on

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...

Make Your Own Arduino Header Pins

Posted by Envistia Mall on

If you've ever made a custom Arduino shield using standard perfboard, you know the two digital IO headers are separated by a non-standard distance and won't line up.Rssalnero on Thingiverse tried using needle nose pliers to bend the pins to match and failed miserably. So he created two simple 3D printed jigs that let you bend an 8-pin header. The first jig bends the correct offset and the second helps you straighten out the ends again. You can see the result in the picture above.t's a pair of jigs for bending an 8 pin header the precise amount needed to...
