AC/DC current measurement using ACS712 sensor and NodeMCU ESP-12E micro-controller.
Getting Started A glimpse of what you will read through this document to get you started on how to measure AC current by using an Allegro ACS712 Current Sensor and the NodeMCU ESP8266 ESP-12F module . Also, how this data could be uploaded to ThingSpeak analytic IoT platform. The Current Sensor This section highlights relevant features that need to be known for this tutorial related to the Allegro ACS712 Hall Effect-Based Linear Current Sensor . Allegro ACS712 Hall Effect-Based Linear Current Sensor Board This section will describe, and highlight the main features of a common Development Board used for IoT projects and compatible with the Arduino IDE platform. NodeMCU ESP8266 ESP-12F module All together A step-by-step process to set up your work environment using the ACS712A and NodeMCU ESP-12E module . Programs This part will walk you through a sequence of programs (sketch), starting from a baseline and eventually modifying until reaching a complete...
