Mr. N is an academic entrepreneur who is already a customer of our level sensors and is very interested in our wireless level sensors through communication. These include asking what kind of wireless technology is used, lora or NB, how long it will last if powered by a battery, and how sealed the sensor is. In addition, as we all know, Australia is a big agricultural country, we introduced our customer agricultural environmental sensors for agriculture, every 100 acres of land can use one of these agricultural comprehensive sensors. Sensor parameters include atmospheric temperature, humidity, PM2.5, wind, wind direction, rainfall, as well as soil temperature, humidity or moisture, PH value, water-soluble oxygen, and even including nitrogen, phosphorus and potassium content of the composite multi-functional sensor, through the battery solar photovoltaic energy and control panel, All parameters are transmitted to the management center via lora wireless or NB wireless. Australia is vast and sparsely populated, and some farmers even have tens of thousands of acres of land, which is a big market if it is promoted.

     By the way to understand the current situation of the Internet of things in Australia, Mr. N said that the development of the Internet of things in Australia is only in its infancy. As such an academic entrepreneur, he is developing a wireless controller called the TOC, which is also, in effect, a gateway. Its built-in battery, Lorawan wireless module, external 12-pin socket, can be a variety of sensor signals, through the gateway or known as the base station into Lorawan wireless signal, but such a product to sell 850 Australian dollars, converted into more than 4000 yuan, too expensive, it is difficult to promote.

      In addition, I learned that the Australian nbiot network can only cover about 60% of the main areas in big cities like Sydney, and the cost of the operator SIM card needs 50 Australian dollars per month. More than 600 Australian dollars a year, or nearly 3,000 yuan. In addition, certain regional lora regional operators will also charge $25 per month. Compared to China, this is too high, is this also a factor in the slow rollout of NB IoT in Australia? You are welcome to comment in the comments section.

      There are also fewer Australian terminal manufacturers, as can be seen from this show, although this is not a communications show or an electronics show. The few companies that do sensor and iot hardware are basically from Europe, China and the United States.

         After three days of exhibition understanding, and communication with major customers in Melbourne, Sydney and friends in the industry, we can draw a simple conclusion: the development of sensors/iot in Australia is not as fast as we think of developed countries. Whether in terms of basic research, or smart hardware and platform construction, Australia may be a big market to be developed in the future. It can also be simply said that the development of the Internet of Things in China is much earlier, much faster and much wider than that in Australia.

       Yesterday, at the end of the show, we went to a small corner booth in the exhibition hall and found what I think is quite a good sensor technology, a very small clamp current sensor. The size of this sensor is 20 ~ 30 mm, and its special place is that it has a self-fetching function, that is, it generates electricity through induction for the magnetic sensor to work, and then sends it out wirelessly. A receiver or router is installed about 10 meters away from the side, which can receive the signal of the sensor and transmit the information through long-distance wireless technology, and a receiver can accept the signal of about 30 sensors around.

       This can not only save energy known as 25% to 30%, at the same time, easy to install, small size, occupy small space, do not need external power supply and built-in battery, the popular self-electricity technology and wireless transmission technology perfect combination. Gu Ge believes that this current sensor application space is very large, and it is also the most advanced current sensor technology seen at present. However, the representative of the booth does not have more information to provide, the price is relatively expensive, the sensor price is more than 300 Australian dollars, the receiver price is more than 400 Australian dollars, asked if this is not locally produced in Australia, the exhibition representative did not directly answer, should not be produced in Australia.

       I do not know whether China's domestic current sensor manufacturers have such technology and products. Officers, if you see this, please tell Gu.

       During the exhibition, Gu talked with a customer who started his own business after leaving a large company in Australia, and learned that the management of some large companies in Australia often emphasized how to reduce costs and reduce expenses. Lack of innovation, lack of research and development of cutting-edge technologies, lack of exploration of new technologies within the industry, a certain degree of formalism. These are basically the same as many large companies in China, and the new technology companies in the United States, even if they are large, are not like this. This may be the Chinese companies should think about the problem, large companies have a strong strength to do research and development, do innovation, but do not do; Small companies, in order to survive, have to do some innovation, but it is difficult, and the speed of progress is slow, so the difference between us and American innovation is often in some way here.
