Bayangkan sebuah situs tambang yang sangat luas dan jauh dari peradaban dan pastinya jauh dari jangakuan sinyal. Sementara beberapa peralatan perlu dipantau dan hasilnya bisa dilihat dari tempat lain yang jaraknya bisa ratusan kilometer dari situs tersebut. Di sisi lain, ada sebuah gudang yang luas pada pinggiran kota dan butuh dipantau secara real-time untuk memastikan […]
Do you have an Arduino or ESP32 project that requires remote control of a mains-voltage device—such as an air conditioner or lamp—via MQTT? Here’s the challenge: most household electronics need significantly higher voltages to operate, while your board only runs on 3.3 to 5 volts. How can one safely close that gap, then? This is […]
Like us humans, the world of IoT devices communicates in its own special way by speaking various languages to share ideas and thoughts. Much like humans navigate through a variety of languages and dialects, IoT devices have their own ‘communication protocols,’ each with unique characteristics and specializations. They have intelligent conversations in this digital environment, […]
Before diving deeper into understanding what the usage MQTT in IoT is, let’s look at the history of MQTT itself. In 1999, Andy Stanford-Clark of IBM, and Arlen Nipper (then of Arcom Systems, later CTO of Eurotech), created MQTT. In its initial version, MQTT helped oil pipeline sensors communicate with satellites. In 2014 OASIS accepted […]
One of the human advantages is the ability to have their own language to communicate with each other, telling how they feel, and exchanging information. We have overcome language differences by agreeing that an understanding of an object remains the same, even if it has a different meaning in another language. And as time passed, […]
