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. read more : RF 433 MHZ TRANSMITTER AND RECEIVER (WITH DEMO) Video Tutorial: Applications: Remote Controls Automation System Wireless Security System Sensor Reporting Car Security System Remote Keyless Entry Package Includes: 1 X RF Wireless Module Pair (433MHZ) Specifications: Range in open space(Standard Conditions)   100 Meters RX Receiver Frequency   433 MHz RX Typical Sensitivity   105 Dbm RX Supply Current   3.5 mA RX IF Frequency   1MHz RX Operating Voltage   5V TX Frequency Range   433.92 MHz TX Supply Voltage   3V ~ 6V TX Output Power   4 ~ 12 Dbm

RF433 MHz Transmitter Receiver Wireless Module This 433 MHz wireless rf module is a superheterodyne ASK (Amplitude Shift keying ) / OOK (On-Off keying based ) module. Design ideal is to use a SAW filter, highly suitable for industry control or bad place for use, strong anti-jamming. Built-in automatic gain circuit (AGC), it will automatically change front-end LNA gain among received signal strength also makes signal output will not be strong or weak signals which caused by phase distortion so that it can rise higher sensitivity. To receive the local oscillation circuit for the PLL lock loop design, no offset, and stability is high. The frequency is 433MHz and the receiver structure is Superheterodyne, the received signal is OOK. After receiving the signal, it will output the TTL signal to the external decoder IC for decoding. It is convenient to the applicant in different products and external components are not necessary to make products be wireless also bring value-added for your products. read more : RADIO FREQUENCY Applications: Remote Controls Automation System Wireless Security System Sensor Reporting Car Security System Remote Keyless Entry Package Includes: 1 x RF433 Transmitter 1 x RF433 Receiver Specifications Operating voltage 3.6~5.5V sensitivity 110dBm Operating Current  5 mA Dimensions  5 x 4 x 3cms  Weight  15 grams

RFM69 FSK Transceiver Module The RFM69 series wireless communication module is intended for global free application at the 434 MHz ISM band. It is a low-power, high-bandwidth module with low cost, stability, and product consistency, capable of transmitting data packets up to 300Kbps. The module has broad applications, including daily life activities that require wireless connection, industrial control, access control, attendance, surveillance, and security industries.The RFM69HCW variant of the module communicates with a host microcontroller using an SPI and supports up to 256 networks with 255 nodes per network. It features AES encryption for data privacy and can transmit data packets of up to 66 bytes long.The RFM69HCW operates at 915MHz frequency and can transmit up to 100mW at 300kbps. These values can be adjusted to match specific application requirements, with an option to maximize range by increasing transmit power and reducing data rate or reducing both for short-range sensor networks with low battery consumption.The module can cover a considerable distance at full power, reaching over 500 meters in open air or transmitting from space to the ground using more complex antennas and modulation schemes. The RFM69 series has various models with different characteristics such as MCU, power amplifier, data interface, and packaging methods. These models can communicate with each other, meeting FCC/CE standards and satisfying clients' authentication needs.
