433MHZ RF Wireless Transmitter Recevier Module with 433MHZ frequency

Original price was: ₹199.00.Current price is: ₹142.00.

433MHz frequency is a commonly used frequency band for all types of equipment that require little power. 433MHz frequency wireless transceiver module, using high-frequency RF technology, so is also called RF433 RF small module

The typical range of a 433MHz RF transmitter and receiver module is generally 20 to 200 meters in open space. However, this can vary significantly depending on factors like the specific module used, the environment (e.g., number of walls, interference), and the power output. Some modules may offer ranges exceeding 300 meters in ideal line-of-sight conditions with a suitable antenna.
