With the advent of low-energy, long-range wireless communication technologies that the Internet of Things has brought, many existing solutions have been given a new look. They are technically much more suitable for real applications. One of these applications is monitoring flammable gases, something of paramount importance to ensure greater safety for people and buildings and essential for identifying and rapidly mitigating an imminent fire or explosion. This article shows the design of such a solution, capable of detecting flammable gases or smoke in the air and monitoring the room temperature by using communication technologies such as Wireless and SigFox.
In the previous article (The Electrical Signals of the Human Body - Part 1 (BM077E)), we showed how electrical signals can be generated in a chemical environment such as the human body, and how they are used for communication between its parts, such as the nervous system, in addition to being responsible for other electrical properties which we observed. We have seen that these signals can be used for our body interaction with technology devices, which is growing in our world. We now continue to detail some of the most important signals and how they can be used.
Scientists researching the possibilities of life on other planets define ecosphere as a region where temperature and other conditions can allow some kind of life to develop. On Earth, we know that life can only exist within a narrow range of temperatures. If too hot or too cold, living beings cannot survive.
In several of our articles, we have dealt with the increasing integration of our body with the environment which surrounds us. Our senses can integrate with electronic devices leading us to what many call transhumanism. Soon, we will not know where our body ends, and a high-tech device begins. We also have an intensification of research to reveal more about our senses and this has led to very important discoveries.
What would a bionics evil genius think about being able to hear very weak sounds from far away such as light footsteps on a carpet or even conversations through walls? Steve Austin, the six-million-dollar bionic man, had those same abilities. He could hear the weakest sounds, even ones produced from many miles away. Of course, the fantastic ears of the bionic man can't he reproduced by simple electronic equipment. Our natural ears are the most sensitive sensor that nature can create, and no other sensor, even an electronic one, could be superior to them.
Smell is one of the chemical senses. The other is taste. They are so called because they sense chemicals. Smells are chemicals because the senses are stimulated by chemical substances present in the air.
