According to the two EU environmental protection orders, since August 13, 2005, manufacturers of electrical and electronic equipment circulating in the EU market must bear the cost of recycling their own scrapped products in the legal sense. Electrical and electronic products placed on the EU market after July 1, 2006 shall not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. The products covered by these two directives include nearly 200,000 kinds of 10 major categories, and most of them belong to Guangdong's strong export of mechanical and electrical products. Guangdong's exports of mechanical and electrical products to the EU account for 20.3% of Guangdong's exports of mechanical and electrical products, and the amount of exports directly affected each year. Will exceed $20 billion.
According to customs statistics, in August, Guangdong's mechanical and electrical products exported 2.2 billion U.S. dollars to the EU, an increase of 17.1% over the same period of last year (the same below). The growth rate was 5.8 percentage points lower than that of Guangdong's mechanical and electrical products in the previous July, which increased by 22.9%. In September, Guangdong The export of mechanical and electrical products to the EU was US$2.25 billion, and the growth rate further dropped to 14.6%. This is the lowest increase in Guangdong's export of mechanical and electrical products to the EU this year, except for February, which is affected by the Spring Festival. The negative impact of the EU environmental protection directive on Guangdong's exports of mechanical and electrical products will gradually emerge. These two directives will not only significantly increase the manufacturing costs and export costs of Guangdong enterprises, but will also expose some products that are not up to standard to the threat of being excluded from the EU market.
According to analysis, the EU's two environmental protection directives will add four major costs to “Guangdong Manufacturingâ€:
The first is the increased cost of recycling electromechanical products. For products placed on the market after August 13, 2005, producers shall pay for the recycling, disposal, recycling and environmental disposal of all their own products. At the same time, the EU has a recovery rate and recycling rate of 70% to 80%. After the two orders are launched, the recycling cost of electronic appliances will be passed on to the manufacturers. Due to the high labor costs in Europe, the recycling cost may make the Guangdong manufacturing industry lose its cost advantage, thus reducing the competitiveness of related export products.
The second is the increased cost due to the detection of hazardous substances. The EU has enacted corresponding laws requiring that the necessary means be used to test to determine whether the product meets the requirements. The manufacturer must identify all the raw materials and components that make up the product one by one, and ensure that no harmful substances are contained. These require the manufacturer to pay certain tests. Costs, thereby increasing export costs.
The third is the increased cost of using alternative materials. Most of the electronic and electrical products produced in Guangdong use six kinds of banned harmful substances. To find alternatives, the cost of the products is increased. The use of substitutes requires improvements in related manufacturing processes and production processes, and some are currently banned. It is also difficult to find suitable substitutes for hazardous substances.

What is 2.4g wireless module?
2.4g line module operating frequency in the range of 24400-2484mhz, can communicate through the scanning protocol, air rate up to 1Mbps, output power up to +4dBm, the module has the advantages of low power consumption, cost-effective. Movingcomm's current 2.4g antenna modules are: IOT04, IOT05, IOT09, IOT18, IOT60, etc. Users can choose a variety of modules with a transmission distance of 50-500 meters according to cost considerations.
Second, the role of 2.4g wireless module
Function 1, for the formation of a star topology wireless communication network, and must be a multi-point star topology, some extraordinary places need wireless communication. On the one hand, the transmitting and receiving module is cheap, and the cost of forming the star topology is relatively low. On the other hand, the transmitting and receiving module can adopt the modular design, which is small in size, easy to use and easy to integrate. For the wireless network with low communication speed and close distance, the transmitting and receiving module is very practical.
Function 2, for wireless multi-channel (parallel) control. Such as complex remote-controlled robots, some places require multi-channel (parallel) control. One method is to use the receiving module to directly connect to the decoder, and then connect to the relays and other electronic components to drive the subsequent controlled object; the other method is to use the receiving module to connect to the single chip microcomputer, and after the data is disposed of, the single chip microcomputer is connected to the relays and other electronic components to drive the subsequent controlled object. Usually a pair of transmitting and receiving modules can achieve up to six parallel wireless control, if the required number of channels is greater than six, you can use multiple pairs of transmitting and receiving modules, and work at the same time to meet the actual needs.
Function 3, used for general serial port, RS232 antenna data transmission, there are usually many control instruments and equipment using serial port, and communication with these devices must meet the requirements of serial port. In some extraordinary places, when the industrial control site must use the antenna transmission mode, it is natural to choose the transmitting and receiving modules mentioned in this article, but it must be explained here that to use this communication mode, the corresponding software must be prepared at the transmitting end and the receiving end respectively to achieve the conversion of file formats, in order to achieve the purpose of wireless communication, if the communication system is full-duplex. It can be achieved by using two pairs of transmitting and receiving modules, working simultaneously.
Third, 2.4g wireless module application field
2.4G wireless module is widely used in wireless health sports products, wireless mouse and keyboard, product information push, wireless remote sensing, wireless ranging system, alarm security system, smart home, toy control, tire pressure monitoring and other fields. With the 2.4G wireless module, all the whole house wireless smart home can be linked together, you can control all the smart home devices through the link of the network, and then you can control the switch of all the whole house wireless home, adjust the brightness of the lamp, adjust the rise and fall of the curtain, etc., through the continuous innovation of technology, The whole house wireless smart home can be controlled by a small white robot voice, can be controlled by a smart scene panel, can be controlled by sensors and so on.
Four, 2.4g wireless module how to choose antenna
In general, the 2.4g wireless module requires an impedance of 50 ohms, a red wire used with 2.4g, a 2.4g folded rod antenna, a 2.4g gold-plated straight head rod antenna, a 2.4g gold-plated elbow rod antenna, and a 2.4g small suction cup antenna. These antennas are special antennas designed for 2.4g wireless communication system, antenna standing wave ratio performance is good, small size, clever structure, easy installation, stable performance, with good anti-vibration and aging ability.
