DC 5V 433Mhz RF Wireless Transmitter Module and Receiver Kit

The TX-ASK is an effective low-cost solution for using the 433 MHz frequency. This ASK hybrid transmitter module is designed with a saw resonator, making it small, cost-effective, and easy to use for designing. However, it's important to note that this 433mhz rf transmitter and receiver kit does not support direct UART communication when connected to PCs or microcontrollers due to the high levels of noise on these frequencies.

The RF module comprises a 433mhz rf transmitter and receiver. The transmitter receives serial data and wirelessly transmits it through RF via its antenna connected at pin4. The transmission rate can be set to 1kbps or 10kbps. The transmitted data is received by an RF receiver operating at the same frequency as the transmitter. This 433 MHz RF transmitter and receiver pair is cost-effective and can transmit signals up to 100 meters (although the antenna design, working environment, and supply voltage will significantly impact the effective distance). It's ideal for short-distance battery-powered device development.

1. How does 433MHz RF module work?

The 433MHz RF module is a wireless communication module that operates on the 433MHz frequency. It is comprised of a transmitter and receiver module that can be interfaced with microcontrollers such as Arduino. The transmitter module sends wireless data to the receiver module, which then transmits it to the microcontroller. To work with the 433MHz transmitter/receiver with the Arduino, the RadioHead library can be utilized.

The transmitter module is designed to be the most cost-effective and straightforward RF transmitter, using an on-off RF transmitter to transmit data. On the other hand, the receiver module has a frequency range of 433.92MHz and an input voltage of 5V, while the transmitter module has a frequency range of 433.92MHz and an input voltage of 3-12V.

2. What is the range of the 433 MHz RF module?

The maximum range of the 433MHz RF module can vary due to different conditions. One source states that, under normal conditions, the maximum range with the antenna is 100 meters. Additionally, the RF 433MHz receiver has a frequency range of 433.92 MHz, as mentioned by another source. However, it's crucial to consider that the range of the module can be influenced by several factors, including interference, obstacles, and the quality of the components used.

3. What is 433 MHz used for?

The 433 MHz radio band is widely used in various household devices for wireless signal transmission. It is also utilized in innovative applications such as wireless doorbells, garage doors, home automation, and access control systems. This frequency band falls within the amateur radio range and is allocated for licensed radio amateurs who can transmit at up to 40 W between 430 and 432 MHz and 400 W between 432 and 440 MHz. Additionally, in certain regions, the LPD433 (low power device 433 MHz) UHF band allows for license-free communication devices. Moreover, 433 MHz is also utilized for wireless connectivity in the Internet of Things (IoT) applications.
