What is 433Mhz RF remote control
What is 433Mhz RF remote control
In the previous chapters, we talked about the transmit power and application range of the RF2.4G remote control. Today, what we want to share is how far is my remote control distance that customers often ask? In fact, this question is a bit general. How far are artificial satellites in space from us? We can all remotely control on earth. So what we must emphasize is the scope of application and what is the terminal equipment? In daily life, it is rare for some remote controls we use to control the distance in the range of 100 meters, so we use this remote control with a range of 100 meters to analyze the relevant technical knowledge.
Different from the RF2.4G remote control, the 433Mhz remote control is a high-power transmitting wireless remote control (RF) with a long transmission distance, which can reach a distance of 100 meters (subject to actual measurement). 433Mhz remote control is also commonly used for car electronic keys.
433Mhz remote control, the communication principle is: the remote control encodes high and low level data, then loads it on the high-frequency circuit and sends it to the air. The receiving module (device end) of the corresponding frequency band can receive the signal, whether it can be decoded, if The coding rules are consistent, that is, the format of the synchronization code, address code, and data code is the same, and the number of digits is the same, and then communication is possible. For example, coding IC 2240/1527, which has the same coding specifications of different manufacturers, can be used together.
Therefore, for the 433Mhz remote control, our Shenzhen Fandou Technology Co., Ltd. sales requirement, the customer only needs to provide each button level rules. A prototype can also be provided to read the level rules of each button.
For the 433Mhz remote control, the closer the transmitting frequency is to 433Mhz, the more ideal the frequency is. The transmission frequency and transmission power are required to be 100% inspected to ensure the quality of the remote control.
The wireless transceiver module adopts radio frequency technology, also called RF433 radio frequency small module. It is composed of a single IC radio frequency front end produced by all-digital technology and ATMEL AVR single-chip microcomputer. It can transmit data signals at a high speed and can package wirelessly transmitted data. ﹑Error detection and error correction processing.
The components adopt industrial-grade standards, work stably and reliably, and are small in size and easy to install. It is suitable for security alarm, wireless automatic meter reading, home and industrial automation, remote control, wireless data transmission and other system fields.
