Log Temperature Sensor Data to Google Sheet using NodeMCU ESP8266

There are many IoT clouds available to store and monitor the data from various sensors. With increasing popularity of IoT, more number of sensors are used every day and these sensors produce anonymous data which are useful to control other devices on the IoT network. These data can be studied further and used to modify design or improve the system performance. The Applications of Data Logging is vast and can be applied in Research Centres, Scientific Labs, Operation Theatres, Patient Monitoring System and many more.

Lora Based GPS Tracker using Arduino and LoRa …

Lora Based GPS Tracker using Arduino and LoRa Shield
In this tutorial we will build GPS tracking system using LoRa, the system will consist of a Transmitter which will read the location information from the NEO-6M GPS module and transmit it wireless over Lora. The receiver part will receive the information and display it on a 16×2 LCD display.

Top Open Source IoT Platforms to Cut Down Your IoT Development Cost
Just like with software, there are several IoT APIs available for different tasks, but most of them usually do not come free. For today’s tutorial, we will be looking at the top 10, very useful (in our opinion) Open Source IoT APIs to help you cut down on your development cost and time. These APIs are Open, free (or have free packages) and can be used by not just professionals but also makers, hobbyist and pretty much anyone who finds them useful and is okay with the terms of use. These APIs are listed in no particular order, were selected randomly across verticals, and are probably not comparable as they perform different tasks.

IoT Based Biometric Attendance system using Arduino and Thingsboard

In this project our aim is to leverage this IoT into the boring attendance system to make it smart and more effective. Most conventional attendance systems available today store the information over a micro SD card and have to be connected to software via a computer to access the information. Here, we will build a biometric attendance system using Arduino that scans for finger print and on successful identification of the person it will log the information to a cloud platform like ThingsBoard by using the ESP8266 Wi-Fi module. This information can then be displayed in the dashboard of ThingsBoard making it available for the required authorities to view and analysis information over the internet without having any direct physical access to the hardware. However the conventional Attendance system without involving IoT can also be built by following the link and Finger print sensor can be further used for many other biometric applications like Voting Machine, Security system etc.

Programming NodeMCU ESP8266 Over-the-Air (OTA) using Arduino IDE

OTA Programming (Over the Air) is a process which allows devices to upgrade their firmware or software wirelessly without any physical access. It uses wireless technology like Wi-Fi, Bluetooth, GPRS or 4G/3G rather than wired serial communication. OTA is used to reprogram the devices like microcontrollers, cellphones, computers, set-top box etc. OTA updates are generally sent for updating the software, resolving the bugs, adding some features etc. With the increasing use of IoT devices OTA is transferred using frequency bands having low data transmission rate (868 MHz, 900 MHz, 2400 MHz).
