WavzNode – An industrial Internet of things node | Part 2 | Electronics

I choose Arduino core to build this project for couple of reasons.  Ease-of-Use. String Community support. Easy to debug. Abundant of resources. Full of necessary libraries. According to last my last blog, I am going to start with Stage 1 of the development. Which is to use Woreless module(WiFi), On-board sensor coupled with Atmega-328P. I will carryout prototyping, firmware development, hardware design, PCB designing. Pretty much everything.  Node designed considering following conditions:           On-Board Sensor.           Internet connectivity - for Cloud data logging.           On-board Memory - For data-logging, in case internet connectivity fails.           Data to be logged in “.CSV” format, with new file on each day.           RTC for Date-Time stamp.           Mini/Micro USB Port - For Config...

WavzNode – An industrial Internet of things node | Part 1

Industrial Revolution 4.0 I believe industrial process monitoring & control should be smart, simple and efficient. Various manufacturing and processing industries demands constant monitoring of critical environmental parameters (Temperature, Humidity, Pressure, vibrations) to maintain product quality. Currently, most of the industry uses wired network of sensors & controllers. These networks have drawbacks such as –Costly to Maintain and complex to deploy, require timely calibration of system, susceptible to external noise, low reliability, high downtime, false triggering of Alarms and requires continuous mains power source. These systems are operated from local PC(RS-232/RS-485), using proprietary PC software. PC software which have complex UI and are irrelevant.  I wish to design the node, -real-time data log. -Simple plug-&-play interface. -Ease of use, installation and maintenance. -Simple to Configure and ability for Over-the-air-pr...

Designing ESP-01 & 12 Upgrader / Flasher Tool

ESP-01 and ESP-12 are widely used WiFi modules in the hacker community, thanks to the esperssif for such a low cost WiFi chip. Esperssif is quit active with the SDK development, And releases new versions almost every month, with some updated AT Commands or other firmware related upgrades. It's quit a tedious to flash/burn the updated firmware into ESP. Many hackers have build simple and nice PCB tools to upgrade/flash ESP. I also thought to build one. So here it is !!! Those who want to know How-To Upgrading firmware of the ESP modules read this article . I use ESP-01 for my small projects. I thought, it will be nice if I build a simple PCB widget, which will allow me to easily flash the latest firmware into ESP8266. For this project, I simply integrated ESP-01 and ESP-12 footprint into single PCB [with RESET+FLASH buttons and GPIO options], in that way, one can add ESP module and flash the firmware with Zero errors. There are going to be two versions of the t...
