Microwave Radar 5.8GHz Module (DFRobot) - SEN0521

The 5.8GHz Microwave Radar Module is an advanced microwave sensor designed for motion detection. Operating at a frequency of 5.8GHz, it transmits electromagnetic waves and distinguishes between the transmitted and reflected waves to identify movement within its detection area. Unlike traditional sensors limited to detecting large body movements, this microwave sensor excels in detecting subtle motions like breathing. It can accurately determine human presence, even when individuals are sitting or sleeping. The sensor outputs the detected results through the serial port or as a high/low level on the I/O port.

Features

  • LoRa SX1276 Wireless Module: Built around the SX1276 chip, the module employs LoRa technology, allowing for long-range data transmission and excellent penetration capabilities.
  • Configurable Output Power: The module's output power can be adjusted from +13 to +20 dBm (up to 100 mW) through software settings, providing flexibility in balancing communication distance and power consumption.
  • Low Power Consumption: During transmission, power consumption ranges from 50mA (+13 dBm) to 150mA (+20dBm), while in listening mode, it requires approximately 30mA, making it energy-efficient for battery-operated applications.
  • AES-128 Encryption Support: The module offers AES-128 encryption, ensuring secure and private data transmission, making it suitable for applications that require data confidentiality.
  • Multipoint Network Capabilities: It supports multipoint networks, allowing the establishment of individual nodes within the network for seamless and efficient communication.
  • Wide Power Supply Range: The module can be powered with a voltage range from 3V to 5V, making it compatible with various power sources and microcontrollers.

NOTE: It is important to solder a 16cm length of cable to the antenna pin before using it since not connecting any antenna can damage it. Optionally, the board has pads to solder an SMA connector with antenna thread.
