433Mhz antenna design and debugging
In the field of wireless communication, spring antennas play a very important role and are often used in conjunction with wireless modules in many projects.
The height of the transmitting antenna and the receiving antenna Sensitivity of the receiver are very important.
The specific 433.92MHzz antenna debugging needs to be adjusted according to the actual product. For this part of the technical support work, you can directly contact C&T RF Antennas Inc. for antenna design and debugging.
You only need to modify the circuit board in advance and reserve the antenna pads and matching devices.
Application for 433MHz wireless modules in the Asia-Pacific region
The wireless module is divided into different frequency bands: 433mhz, 868MHz, 915MHz, etc.
The 433MHz wireless module is a license-free ISM open frequency band in China, and there is no need to apply for authorization to use the 433MHz frequency band.
Therefore, the 433MHz frequency band is widely popular in various industries in the Internet of Things in China and the Asia-Pacific region.
However, the 433MHz wireless module has strong diffraction ability, long transmission data, strong anti-interference ability, and other advantages that make it survive in the IoT market.
The application fields of 433MHz wireless modules are also very extensive. Next, I will give you some examples of common areas in our lives.
1. Smart home security alarm
In addition to money, what is most important to people nowadays? It is their own personal safety. Robbery, robbery, theft, and even some girls who have endangered their safety are not rare. Many of these criminals did it when the victim was not paying attention.
The smart home security alarm system can remind us in the fastest time. For example, under the security system, criminals can be reminded immediately when they steal into the house late at night. Or strangers often hover at the door to remind them.
The 433Mhz wireless transceiver module uses LoRa wireless technology, and the transmission distance can reach 2-5 Km in towns and 15 Km in suburbs. The ultra-low-consumption shutdown mode is also widely used in the field of smart home security alarms.
2. Remote control
Everyone is familiar with the remote control, the TV remote control, the air conditioner remote control, the car key, and so on you come into contact with all wireless modules that need to be used. These all need to use the wireless module!
3. Remote meter reading
With the rapid development of the Internet of Things era, the traditional way of manual meter reading from door to door one by one will be gradually eliminated this era.
Remote meter reading can greatly reduce our manpower, material resources, and time, so smart Remote meter reading will become a development trend in this field.
The high-power wireless 433MHz wireless module adopts LoRa TM spread spectrum modulation frequency hopping technology, its communication distance and receiving sensitivity are far beyond other FSK and GFSK solutions.
Its multiple transmission signals occupy the same channel without being affected, making it super anti-interference, it can be widely used in remote industrial control, remote meter reading, and other fields.
4. People flow monitoring
The popularity of the Internet of Things has brought us too many conveniences. In the past, it was a difficult problem for you to know the accurate flow of people around you, but today with advanced technology, it is no longer a difficult task.
The core element LoRa module can monitor the flow of people.
It is based on LoRa radio frequency, 868MHz (common in North America), 915MHz (common in Europe), and 433MHz (common in the Asia Pacific). We can choose its frequency according to different situations in different regions.
Support long-distance transmission, transmission distance>5000 meters; adopt multi-level sleep mechanism, transmit power adjustment mechanism, wireless wake-up mechanism, the average receiving current of the module in wireless wake-up mode is 2uA-20uA, suitable for long-distance wireless that requires battery power transmission.
Besides the Internal Antenna 433MHz RF Module 433MHz Receiver, C&T RF Antennas Inc also supplies the spring antenna coil helical antenna with 315 Mhz, 433 Mhz, 868 Mhz, 915 Mhz, Wifi, GSM, etc.
