Connected Weighing scale using HX711 and ESP8266

HX711 and ESP8266

Since I got into Home Automation System, I have always wanted a central system with as much as information about me starting from my food habit to each and everything that can be measured or collected. You can say that it is greatly influenced by JARVIS of Iron Man which came around my Engineering days. Coming to the topic, I recently managed to connect a regular bathroom weighing scale to my Home Automation System (OpenHAB) using MQTT. So basically this post is all about how to do that. For the weighing…

ESP32 LoRaWAN Node using Arduino

Bikash Narayan Panda

To test out the recent addition in my lab that is the LoRa gateway, I needed one LoRa node also. LoRa modules are available to be used with Arduino as well as Raspberry Pi and are pretty cheap too. However, you can get complete LoRa module with ESP32 and OLED display at pretty low price from Banggood, and they fit the purpose. And by using these, you don’t need to jumble around jumpers. In this post, I have covered how to make a simple, cheap LoRa node that can send…

RAK831 LoRa Gateway

Lately, I have been working with LoRAWAN and I don’t have Lora gateway around. As you might be knowing LoRAWAN network requires a gateway to push data to the internet. As Lora is not an IP based protocol the gateway helps it in doing so. Basically, multiple LoRAWAN nodes transmit data to the gateway and the gateway transfers the concentrated data to server backend. Server backend which resides in the cloud contains a network server which helps in managing the network and the application server which is responsible for the data and…

Access Watchdog Timer of Raspberry Pi using JAVA

Bikash Narayan Panda

This tutorial is all about using the watchdog timer of Raspberry Pi by using JAVA. For this, we are going to use Pi4J library. Watchdog Timer: “A watchdog timer (sometimes called a computer operating properly or COP timer, or simply a watchdog) is an electronic timer that is used to detect and recover from computer malfunctions. During normal operation, the computer regularly resets the watchdog timer to prevent it from elapsing, or “timing out”. If due to a hardware fault or program error, the computer fails to reset the watchdog, the timer will elapse and generate a timeout signal.…
