Reference Title: 1 Set 433Mhz RF Superheterodyne Receiver Transmitter Module Kit with Antenna for Arduino/ARM/MCU Description: 1. Receiver Module: Features: WL101-341 superheterodyne wireless receiver module receives UHF ASK demodulators supporting ASK and OOK modulation. The receiver module has high sensitivity (-110dBm), Low power performance, along with high dynamic range (greater than 60dB). The module uses a highly integrated chip, built-in front-end low noise amplifier, mixers, filters, frequency synthesizer circuit, etc., can maximize signal optimization. Low power consumption Good selectivity and suppression of spurious radiation. Good local oscillator radiation suppression, multiple receiver modules to work with (i.e., 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. Application environment: Remote control switch, receiver module, motorcycles, car anti-theft products, home security products, electric doors, shutter doors, for windows, remote control socket, remote control LED, remote audio remote control electric doors, remote control for garage door, remote control retractable doors, remote controlled volume gate, pan doors, remote control door opener, door closing device control system, remote control curtains, alarm host, alarm, remote control motorcycle remote control electric for cars, remote control MP3.
