433 MHz RF receiver module is the most common and cheapest RF receiver for commercial use. This module helps to receiver the 433MHz frequency commonly but it also has a node on it that is changeable by users for different frequencies. The variable node can adjust the frequency from 315MHz to 433MHz.

The module can receive the data but it is unable to decode and view the data from the receiver without using any third device. Most of the time smart boards and microcontrollers interface with the receiver. The output of the module comes in an encoded form that is decodable through programming and encoders. On the other hand, it works well with the 433 MHz RF transmitter module.

Applications:

1. Home automation
2. Transmit Serial data for a short distance
3. Car security system
4. Wireless logging
5. Short distance communication

Features:

1. The Transmitter offers one-way communication through 433.92MHz frequency at a 1Kb data rate
2. It operates at 3-12V which is the power operating volts of most of the microcontrollers and boards.
3. The module uses the ASK modulation method to transmits the data.
4. It is one of the low-cost power effective modules for both commercial and developers.
5. 433MHz Transmitter is one of the oldest RF transmitters and it has a lot of applications and examples on the internet which helps to achieve interfacing with almost every application.

CMT2210/17LH is a low power, high performance OOK RF receiver, suitable for wireless applications with 315 / 433.92 / 868 / 915 MHz and nearby frequency points in a ISM band. The CMT2210/17LH is a real plug and play chip. The CMT2210LH operates in a band of 300 – 480 MHz. While the CMT2217LH operates in a band of 300 – 480 MHz by default and can be configured through a CMOSTEK tool to operate in a band of 300 – 480 MHz.
The change of RF frequencies can be fulfilled by selecting crystals with different frequencies. The crystal frequencies corresponding to different RF frequencies can be read from the RFPDK interface. This chip is capable of a data rate range of 0.5 – 40 kbps and it is optimized to 1 – 5 kbps as factory setting, ideal for pairing with the low-cost transmitter based on the encoder or MCU.

The  RFM95W transceivers feature the  LoRaTM long-range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using Hope RF’s patented LoRaTM modulation technique RFM95W can achieve a sensitivity of over -148dBm using a low-cost crystal and bill of materials.

The high sensitivity combined with the integrated +20 dBm power amplifier yields an industry-leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity, and energy consumption.

The RFM119W/RFM119SW is a high performance, highly flexible, low-cost, single-chip (G)FSK/OOK
transmitter for various,240 to 960 MHz wireless applications. It is a part of the HOPERF Next Gen RFTM family, which includes a complete line of transmitters, receivers and transceivers. TheRFM119W/RFM119SW provides the simplest way to control the data transmission. The transmission is started when an effective level turnover is detected on the DATA pin, while the transmission action will stop after the DATA pin holding level low for a defined time window, or after a two-wire interface (TWI) command is issued. The chip features can be configured in two different ways: setting the configuration registers through the TWI, or programming the embedded RFPDK. The device operates from a supply voltage of 1.8 V to 3.6 V, consumes 27.6 mA (FSK @ 868.35 MHz) when transmitting +10 dBm output power, and only leak 20 nA when it is in sleep state.
