                  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
