LR35B 315 MHz superheterodyne receiver module for ASK and OOK signals

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The LR35B-315MHz is a compact superheterodyne receiver module designed for receiving wireless signals at 315 MHz. The module supports ASK/OOK modulation and provides high sensitivity and stable reception compared to simpler superregenerative receivers. It is suitable for remote controls, alarm systems, home automation, wireless sensors, and other applications requiring reliable signal reception. The digital data output can be easily connected to microcontrollers such as Arduino, ESP32, and other control systems.

The module is highly sensitive and produces a significant amount of noise, therefore advanced synchronization and data validation are required.
