RF Wireless Transmitter & Receiver Module FS1000A 433MHz

RF Wireless Transmitter and Receiver Module FS1000A 433MHz

This FS1000A-based RF wireless transmitter and receiver module provides a simple, economical way to add long-range wireless data transfer to your Arduino, IoT, robotics, or home automation project. Built for 433MHz operation, the pair delivers stable data transmission with low interference when paired with a suitable antenna and proper wiring.

Key Features

• Frequency: 433MHz – clear performance in many regions for remote control and telemetry.
• Includes both transmitter and receiver modules for two-way development and testing.
• Compact and lightweight design for easy integration into embedded systems.
• Works with common Arduino libraries such as VirtualWire, RadioHead, and RCSwitch.
• Long-range capability – up to 100+ meters in open space with a proper antenna and line of sight.
• Low power consumption on the transmitter for battery-powered projects.

Technical Specifications

• Module model: FS1000A (transmitter) with compatible 433MHz receiver
• Operating frequency: 433.92 MHz (nominal)
• Supply voltage: typically 5V (check module labeling and use proper regulation)
• Modulation: ASK/OOK compatible signaling for simple digital data
• Typical range: up to 100+ meters (open area, with antenna)
• Interface: simple data input/output pins for MCU connection

Pinout and Wiring Tips

• Transmitter pins: VCC (5V), GND, DATA (digital input)
• Receiver pins: VCC (5V), GND, DATA (digital output), sometimes additional address or enable pins depending on the receiver variant
• Use a common ground between your microcontroller and the module for reliable data transfer.
• Add a pull-up resistor or brief timing checks on the DATA line if you see unstable readings.

Software and Libraries

Common Arduino libraries that work well with FS1000A modules:

• VirtualWire – simple encoding/decoding for ASK/OOK modules
• RadioHead – supports many RF modules and more robust protocols
• RCSwitch – useful for basic remote control signal emulation

Optimizing Range and Reliability

• Use an external quarter-wave antenna for 433MHz (approx. 17 cm) on both transmitter and receiver to maximize range.
• Place modules away from noisy power supplies, motors, or large metal objects that can cause interference.
• Test in open space and then evaluate in the final installation environment to determine real-world performance.
• For critical applications, add simple error checking or packet ACKs in your firmware to improve reliability.

Typical Applications

• Wireless sensor networks and telemetry
• Remote controls for gates, shutters, and lighting
• Home automation sensors and wireless triggers
• Robotics control and simple data links between modules
• Educational projects and prototyping with Arduino and other microcontrollers

Package Contents

• 1 x FS1000A 433MHz transmitter module

Regulatory and Safety Notes

Operate the module within local regulations for unlicensed 433MHz use. Always verify permitted transmission power and antenna requirements in your region before deploying long-range or commercial systems.

Quick Start

1. Connect module VCC to 5V, GND to ground, and DATA to a digital pin on your MCU.
2. Install a compatible library such as VirtualWire or RadioHead in your Arduino IDE.
3. Load an example transmitter sketch on one board and the receiver example on another to confirm basic communication.
4. Attach antennas and test range in an open area to verify performance before final installation.
