ماژول گیرنده وایرلس LR45B از دسته ماژول فرستنده گیرنده رادیوییست که از پروتکلهای انتقال بر پایه امواج رادیویی فرکانس
433 مگاهرتز استفاده میکند. این ماژول گیرنده بی سیم بر اساس چیپ ارتباطی LR45B ساخته شده که دارای توان مصرفی پایین، حساسیت بالا، عملکرد خوب و قدرت جلوگیری از تداخل است و می تواند سیگنال ورودی AM را دریافت و خروجی سیگنال دیجیتال داشته باشد و تمام تنظیمات IF و RF به صورت خودکار بر روی ماژول انجام می شود.
Description:
DL-LR45B is a micro-power, highly sensitive, superheterodyne RF receiving module. It is a high performance, cost-effective receiving module with simple peripheral circuit. It has high stability, and strong anti-interference capability. The typical frequencies of applications ranging from 425~525Mhz, while 433.92MHz is commonly used. The peripheral components are the least of the similar superheterodyne reception schemes.
This RF receiving module is compliance with European and American radio security regulations, can be directly applied to your wireless products, and a variety of embedded applications, to avoid tedious high-frequency performance debugging, effectively shorten the development cycle.
DL-LR45B is a real "high frequency antenna AM signal input, digital signal output" receiving module. All RF and IF tuning is done automatically on the chip, which eliminates the manual adjustment process in the development and production, will reduce your R&D costs and enhance the product competitivenes.
