این مجموعه فرستنده و گیرنده وایرلس بر اساس مدولاسیون ASK عملیات ارسال و دریافت سیگنال را انجام می دهد و دارای ابعاد کوچک و توان مصرفی پایینی بین 2.7 ولت تا 5.3 ولت می باشد. این ماژول دارای حساسیت بالا و پایداری مناسبی می باشد.
این ماژول دارای فرکانس کاری فرستنده و گیرنده 315 مگاهرتزی است که خاصیت عدم تداخل را به ارمغان می آورد. نرخ ارسالی این ماژول 4.8 کیلو بیت بر ثانیه و پهنای باند ارسالی مورد نیاز آن 2مگاهرتز است.
از ماژول گیرنده H3V3E 3V به دلیل حساسیت بالای آن و پشتیبانی تا برد حدود 120m در دربهای ضد سرقت هشدار دهنده، ارتباط بیسیم و ... استفاده میشود که به دلیل ارزان بودن، حجم و وزن کم کاربردهای متنوعی دیگری نیز دارد.
ببیشترین کاربرد ماژول فرستنده H34B در دربهای ضد سرقت، سوییچ های وایرلس، آلارم ها امنیتی و پروژههای اینترنت اشیاء IOT است.
ست کامل این دو محصول در ساخت پروژههای عملی و در اینترنت اشیاء IOT طرفداران زیادی پیدا کرده است.
Description:
The ASK superheterodyne receiver module using high-performance RF integrated chip and high- Q dielectric resonator frequency stabilization, built-in automatic temperature compensation circuit, with ultra-small size (18 * 12 * 2.1mm), low power (280uA), wide supply voltage range (2.7-5.3v), high sensitivity, high stability, high anti-interference, high cost, are all kinds of remote control systems and wireless data transmission system is the ideal choice.
H3V3E Receiver and H34S Transmitter Module is a pair set of an H3V3E wireless Receiver and an H34S wireless Transmitter, which is matched and specialized for a wireless remote control set.
The H3V3E Receiver is a 315MHz ASK superheterodyne receiver module which is tuning free, high -performance RF integrated chip and has a high-quality dielectric resonator frequency stabilization. With a built-in automatic temperature compensation circuit, a tiny size, low power consumption (280uA), low second harmonic, wide supply voltage range (2.7-5.3v), high sensitivity, high stability, high anti-interference, it is the best replacement of typical superheterodyne and super regenerating receivers. It can widely be used in home and industrial applications such as all kinds of remote control systems and wireless data transmission systems.
The H34S wireless Transmitter is a 315MHz ASK wireless transparent transmitter which is tuner free and is matched with the H3V3E wireless receiver. It is so user-friendly in installing and applying. It is tiny, low power consumption, high stability, and high anti-interference, which makes it suitable for remote controls and other portable and compact applications. It can widely be used in control light systems, electronic remote toys, electrical appliances, etc.
Receiver Features:
