A Arduino/ESP32 project on using PZEM Energy monitoring module to measure power consumption (Home/Devices) and publish the data using MQTT. Same data is received by OpenHAB for monitoring and integration for HA.

LoRaWAN-Energy-Meter

A LoRaWAN enabled Energy monitoring device using ESP32 and PZEM004T Energy Monitoring Module.

Ultrasonic-Sesnor-With-Raspberry-Pi

Code for using HCSr-04 ultrasonic sensor with Raspberry pi using JAVA. The library used fro this is Pi4J

Arduino-Node-RED-Websocket

This is an example code for communicating with any Websocket [In this case Node-RED] server from Arduino.

Dual-UART-Raspberry-Pi

A JAVA project around adding an additional serial port to the Raspberry Pi. The whole idea is around the usage of a multiplexer.

Linkit7688-Python-Firmata-MQTT-Example

Example of using Python to interact with I2C sensor with Firmata to read data from the Atmega32u4 controller and publish the smae using MT7688 MPU available in the Linkit7688 DUO module.

Aruco-NodeJS

A simple Aruco marker Generator developed on top of NodeJS. It exposes HTTP POST endpoint to make request and get resultant marker in SVG/png/jpeg format.

smarty

A full stack e-commerce solution built with Nuxt.js, VueJS, Node-RED. The stack is fully containerized using Docker. Duplicati is used to backup docker volumes periodically and portainer is used to expose docker health matrices to make it moniterable.

Pi-Email-Alert

Email Notifier is a Raspberry Pi based project using SenseHAT along with the Pi that notifies when the user gets any new email. Right now it shows whenever it gets a new email irrespective of the sender and the content. But it can be customized and priorities can be assigned so that it will notify only when an important email is received. Any model of Raspberry Pi (Except Raspberry Pi 1 A/B) can be used for this project provided it has an active internet connection. The user can also integrate other services like social media notifications, which I will cover in some other post. As a notification, the RGB LEDs present over the SenseHAT is used and produces and email icon, ehich blinks if a new email is received. Again the LEDs can generate many colors and generated icon for notification can be customized depending upon the sender of the mail and priority. Instead of SenseHAT external WS2812B based modules like neopixel can also be used with a little bit of tinkering of the code or even normal RGB LEDs can be used with GPIOs. The code is written in python.
