In this tutorial you will learn about publishing and retrieving sensor data from dweet.io cloud using a mobile app developed with Evothings Studio. The example build is 100% Apache Cordova compliant, and this way you can also easily add Dweet capabilities to your existing projects! An IoT sensor main task is to generate data and passing it on to the … Read More
This article is all about connecting your NXP Hexiwear device to an iOS or Android phone or tablet using Bluetooth Smart (BLE). The Hexiwear is a multi-sensor device based on the ARM Cortex M4 architecture, with a sidekick ARM M0 for the BLE connectivity and an on-board array of sensors in order to become aware of the world around it. … Read More
Visualization is an important part of any IoT deployment, especially when you are using sensors such as temperature, humidity, light etc. Plotting sensor data on a live updating line chart is what we discussed in our second installment, however, if you have a more continuous form of data incoming, such as a stream, you may want to visualize it as … Read More
In a previous tutorial on Bluemix, we successfully published TI SensorTag readings to IBM Bluemix IoT cloud service using MQTT API and our mobile app that was developed Evothings Studio. In this tutorial, we’ll use the same sensor device from Texas Instruments, adding to the mobile app a JavaScript chart library for visualising the SensorTag readings on a line chart … Read More
Storing event data in a secure and stable cloud is a necessity for many IoT deployments. Imagine having a network of devices that are concurrently collecting ambient temperature, humidity and light levels at an industrial plant. All of these devices will generate events that are required to be captured and stored. Typically, this network of devices would need one or a … Read More
