433Mhz Superheterodyne RF Receiver and Transmitter Module
Br 750.00
A 433 MHz superheterodyne RF transmitter and receiver pair is a low-cost, short-range (30-100m) wireless communication module set using ASK/OOK modulation for DIY electronics (e.g., Arduino). The superheterodyne receiver provides improved sensitivity and noise reduction compared to simple super-regenerative types.
Support ASK / OOK modulation, the receiver sensitivity of -108dBm
Operating frequency: 433.92 MHz, bandwidth of about ± 150KHz
mains input voltage range: 2.2V-5V
Working current :2.1mA (Requirement:VDD=5V)
Quiescent Current: 1uA
Low power consumption
good selectivity and spurious radiation suppression, and easy to pass CE / Fcc international certification
Good local oscillator radiation suppression, multiple receiver module to work with (ie, more than single income) and will not interfere with each other, used together without affecting the receiving distance
multiple transmission rates, the general module for 2KHz, up to 10KHz
Temperature range: -40-85 °C
External antenna: 32cm single core wire, wound into a spiral
433 Mhz Superheterodyne RF Receiver and Transmitter Module ASK kits with antenna For Arduino uno Diy kit 433Mhz Remote controls.
These RF modules are very popular among the Arduino tinkerers.
The 433MHz is used on a wide variety of applications that require wireless control.
These modules are very cheap and you can use them with any microcontroller (MCU).
Components
Transmitter (e.g., FS1000A/XY-FST): Simple module with VCC, GND, and Data pins; acts as a basic oscillator.
Receiver (e.g., XY-MK-5V): More complex, often featuring superheterodyne, designed to filter out unwanted signals.�
