What is Zigbee? ZigBee is a personal-area network standard. ZigBee specification considered as an alternative to Wi-Fi and Bluetooth for some applications. Unlike LoRa and Wi-Fi, multiple central controllers can be used for Zigbee. Zigbee is the name of the specification of a set of high-level wireless communication protocols for use with low-power digital broadcasting, based on the IEEE 802.15.4 … [Read more...]
What is LoRa? What Are the Differences Between LoRa and WiFi
What is LoRa? What Are the Differences Between LoRa and WiFi? WiFi is limited in range, consume huge battery. LoRa is specially designed for the IoT devices. LoRa stands for Long Range. LoRa gives long-range transmissions of more than 10 km in rural areas with low power consumption. It is a patented wireless data communication technology developed in 2012. LoRa is a wireless communication standard … [Read more...]
Big Data Analytics in Internet of Things (IoT)
What is the Role of Big Data Analytics in the Internet of Things (IoT)? We can connect all the things to the cloud database & find the pattern. A voluminous amount of data have been produced since the advent of the Internet of things (IoT) devices. Data are not useful without analytics. Numerous solutions have enabled to obtain insight into large data generated by the devices. These solutions … [Read more...]

Wearables and Internet of Things : Part IV
In the previous part of this series, we discussed about few of the use cases. This is the Forth Part of Wearables and Internet of Things Series. In this part, we have disccused about usage in production and logistics, field service. Production and logistics Due to its flexibility and sensorimotor capabilities, humans will remain an important part of production and … [Read more...]
IoT Prototyping : Pushover Ready to Use Android App for Push Notification
A button press sending a push message and email from ESP32 to Android is most wanted project. It is limited by people's abillity to develop Android app. I was finding an easy way for the readers. I re-discovered and tested Pushover with Node-RED on IBM Watson IoT platform. Within 15 minutues with minimum clicks I received beutiful push message from IBM Watson IoT platform with ESP32 HTTP POST on … [Read more...]
Arduino ESP32 : HTTP(S) POST Request to IBM Watson IoT on Button Press
Here is How to Send an HTTP POST Request to IBM Watson IoT on Button Press from Arduino ESP32. The basic is dependent on our earlier two separate examples, first is the set of working examples of codes for IBM Watson IoT and second is the example of using a button press to make a LED turn on for a pre-defined time. Earlier, we had another example of using Blynk to send a basic push message on a … [Read more...]
Cloud Based SMS vs Push Notifications for IoT
A Brief Article on Cloud Based SMS vs Push Notifications for IoT Will Help the Developers to Choose Between Two Options With Maximum Delivery Rate. Obviously, we can use a GSM module with 1-2 IoT setup. But when the number of devices increases, Wi-Fi becomes the obvious choice for connectivity. Furthermore, the GSM module will demand a SIM card and SIM card commonly have some payments to send SMS … [Read more...]
