HW - M21 microwave induction module adopts the planar antenna transmitting and receiving. Induction object for moving objects (or car), after induction to the output voltage signal, for active microwave induction, induction Angle of 180 * 180 °, former hemisphere.Widely used in security monitoring, intelligent systems, control of lamps and lanterns, automatic doors, garage, corridor, roads, etc


Features:

  1. Is not affected by temperature, humidity, air flow, such as dust, noise, light and dark, strong anti-jamming capability.
  2. microwave module is a pattern to launch out, no dead Angle blind area, wide coverage.
  3. microwave is reflected more easily in the process of transmission, sensitivity inside will be better, outdoor is a bit poor.
  4. can signal through the glass, obstacles such as trees, plastic (this will make the induction distance less)
  5. professional design planar microstrip antenna, low power consumption, ROHS, high product consistency.

Package Includes:

1 x HaiWang HW-M21-2, 10m, Microwave Radar Sensor Module

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
