The BX404 PIR Motion Sensor is a smart, low-power digital passive infrared sensor designed for accurate human motion detection in IoT, automation, and security systems. It directly interfaces with up to two conventional PIR sensors via a high-impedance differential input, ensuring reliable detection with minimal interference.

The on-chip digital circuit processes PIR signals and provides stable digital outputs when motion is detected. Timing parameters can be set by connecting corresponding inputs to DC voltages, offering flexibility for different applications. With a 120° wide detection angle, 12-meter sensing range, and ultra-low static power consumption (<11µA), this sensor is ideal for energy-efficient smart devices.

Note: Refer to User Manual in the ATTACHMENTS section for more info. regd. the product.

  5. Wide detection angle of 120°
  6. Long sensing distance up to 12m
  7. Low static power consumption <11µA
  8. Adjustable timing via DC voltage inputs

Package Includes:

1 x SmartElex BX404 PIR Motion Sensor

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.
