433MHz Wireless RF Tx Rx Transmitter Receiver Module Green

This FS1000A is the simplex Tx Rx 433MHz RF module. The transmitter/receiver pair operates at the frequency of 433MHz and at the rate of 1Kbs – 10Kbps. 

An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected to pin4. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.

This is an easy-to-use module and can be easily interfaced with Arduino, ESP866, ESP32, etc. it can transmit signals up to 100 meters (the antenna design, working environment, and supply voltage will seriously impact the effective distance).  This is the best choice for short distance communication, battery power device development.

Instruction

Only simplex LOS communication is possible. The transmitter can only transmit data and the receiver can only receive it, so you can only send data from point A to B and not from point B to A.
