Description

433MHz RF Wireless Transmitter and Receiver Kit is a simple, low-cost wireless communication set used for sending digital signals over the air. It is ideal for remote control projects, wireless sensors, alarms, and Arduino/ESP32 DIY applications. The kit typically includes a 433MHz RF transmitter module and a 433MHz RF receiver module that work together for basic one-way data transmission.

Key Features

Frequency: 433MHz (ISM band)
Kit Type: RF Transmitter + Receiver pair
Supports common DIY RF protocols (with encoding/decoding libraries)
Works with microcontrollers: Arduino, ESP32, ESP8266, STM32
Easy wiring (VCC, GND, DATA pins)
Suitable for remote ON/OFF and simple wireless sensor data

Full Specifications (Typical)

Exact range and performance depend on antenna, voltage, environment, and module type.

Transmitter Module

Operating Voltage: typically 3V–12V (many common TX modules)
Output Power: increases with higher supply voltage (within rating)
Data Input: 1 digital data pin (ASK/OOK modulation)
Use: Sends data from MCU encoder/library to air

Receiver Module

Operating Voltage: typically 5V (some RX modules support 3.3V versions)
Data Output: 1 or 2 digital data pins (varies by board)
Modulation: ASK/OOK reception
Sensitivity: suitable for short-to-medium range DIY links

Communication

Modulation: ASK / OOK (most common 433MHz cheap modules)
Direction: Usually one-way (simplex) per transmitter/receiver pair
Recommended Antenna: external wire/coil antenna for best range

Applications

Wireless doorbell / remote switch projects
Home alarm and sensor transmission
Wireless temperature/humidity sensor nodes
Arduino remote control / RC switches
Garage-style remote signal experiments
IoT prototypes (simple RF link)

Used In

Arduino UNO/Nano wireless projects
ESP32/ESP8266 with encoding libraries
PT2262/PT2272 style remote control circuits
DIY home automation triggers (with proper receiver decoding)
