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...]

Kalman Filter to Stabilize Sensor Readings

Kalman Filter Commonly Used to Stabilize Sensor Readings. The Kalman filter reduces the errors of raw measurements, provides estimates for quantities. The Kalman filter is widely used in robotics, navigation, GPS, biomedical, electronic control circuits of ubiquitous communication systems such as radio and computer. It is a mathematical model which can be applied as a snippet. The Kalman filter is … [Read more...]

What is Deniable Encryption in Cloud Storage?

Deniable Encryption is like tit for tat. Let us as assume, you want to decipher an encrypted file of your enemy. If an encrypted file gives you wrong information, you are likely to miss it. The required effort to find the correct file will consume too much time. Deniable encryption is a type of encryption that allows to convincingly deny that usable data is encrypted or keeps no way to be able to … [Read more...]

How to Create Custom Parts for Fritzing

Fritzing is an underappreciated Free Software with own standard. Few parts are sometime missing or you simply need to create your own part or board. Fritzing breadboard view can be made far superior looking than the default look provides. Commonly peoples open some file in Fritzing, or "draw" the circuit and simply forget about it. Tinkercad looks great because the parts are nicely designed. … [Read more...]

Connecting ESP32 Arduino with DHT11 with IBM Watson IoT

Earlier, we described how to create graph on IBM Watson IoT dashboard by using the default widgets. In previous guide, we described how to use ESP32 Arduino with DHT11 sensor. Here is the Code and Diagram to Connect ESP32 Arduino with DHT11 with IBM Watson IoT and Get Odometer Like Gauges on Dashboard. For this guide, you will need : Reading the above linked guides for setup and materials … [Read more...]

ESP32 Arduino with DHT11 Sensor : Connection & Code

Here is Connection & Working Code for ESP32 Arduino with DHT11 Sensor. We will use Adafruit's libraries for DHT11 and DH22 Temperature Humidity Modules. For using DHT11, DHT21, DHT22 with non-ESP32 Arduino please read our previous guide on Arduino Temperature Humidity Sensor. For ESP32, it is mandatory to have the common required setup for Arduino IDE (ESP32 does not work with Arduino IDE out of … [Read more...]

Which One is Preferred to Make a Smart Doorbell – Raspberry Pi or ESP32 Arduino?

Ideal answer is none. If our previous publication on Watson Visual Recognition with cURL beside guides like sending Push Notification via Watson IoT giving hope of ultra-modern DIY project, then such hope must be killed. We will not supply ideas, projects which will fail with time. Smart Doorbell if used for security purpose demands a commercial solution. DIY solutions mostly for fun at … [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...]
