The HyperText Transfer Protocol (HTTP) is a client-server protocol powering most of World Wide Web. Every time you surf the web, your browser is sending HTTP request messages for HTML pages, images, scripts, and styles sheets. Web servers handle these requests by returning response messages containing the requested resource, completing the HTTP request-response cycle. Just like your browser or mobile..
This piece is here to introduce you to the Server and Client Concept. Firstly, how does the Server/Client concept work within Internet of things? The client is the device that initiates the communication. The server is Ubidots (or any other server connection), that will accept connections and manage the data transfers using a simple protocol..
Industrial process control has long been associated with legacy systems in the shop floor. As Internet technologies continue to advance, bringing increased security and connectivity, manufacturers have begin to turn to connected devices to bring their industrial processes online. This video, made by our friends at VERSE Technology, shows a practical example of how a..
The Internet of Things has brought a lot of formerly complex device applications into the homes of many craft brewers and wine makers. Applications with level sensors have been used for decades in large refineries, water treatment plants, and chemical plants. With sensor prices falling, now both industrial and DIY can monitor the volume of..
Build and deploy a soil moisture and temperature sensor using a Particle Device with Ubidots Platform. Nothing will replace walking out and handling soil for yourself, but today’s technology has made it possible to remotely monitor soil and track parameters that are unmeasurable to the human senses. Soil probes like the SHT10 have advanced technologically..
