3pcs RX531 433MHz Lead-free Environment-friendly Wireless Receiver Module High Sensitivity Super Heterodyne Super Anti-jamming 2.2V-5V DC

Features: The RX531 receiving module is a wireless receiving module based on the super-disturbing interference chip WL531R. It is a UHF ASK receiving and demodulating machine that supports ASK and OOK modulation. The receiver module has high sensitivity (-112dBm) and a high dynamic range (greater than 60dB). The module uses a highly integrated chip, built-in front-end low-noise amplifier, mixer, filter, frequency synthesizer and other circuits, which can optimize the signal to a large extent. - Support ASK/OOK modulation mode, the receiving sensitivity reaches -112dBm; - Adopt environmentally friendly materials and production and processing technology, can pass ROHS environmental certification - Good selectivity and stray radiation suppression, easy to pass CE/Fcc international certification; - Good local oscillator radiation suppression capability, multiple receiver modules can work together (ie, single-shot and multi-receipt) without interfering with each other, and use together does not affect the receiving distance; Operating frequency: 433.92 MHz, bandwidth about 150KHz; Power supply voltage input range: 2.2V-5.0V; Temperature range: -40-85 C Size: 23.5 9 1mm Number symbol name Description 1 ANT Antenna pin RF signal output, directly connected to the antenna 2 GND Power ground pin Power ground, can be connected to the antenna housing shield 3 DO Data output pin When the module receives the carrier of the corresponding frequency, the pin outputs a high level; 4 DO Data output pin When the module does not receive the carrier of the corresponding frequency, this pin outputs a non-standard square wave. 5 GND Power ground pin Power ground Application Range: - Motor type strong dry resistance - Wireless power switch, socket - Remote control curtains, access control, electric vehicles - Security, monitoring system - Hotel room control - Smart home products Package Included: 3 x 433MHz Lead-free Environment-friendly Wireless Receiver Module
