GY-271 QMC5883L 3-Axis Electronic Compass Module Magnetic Field Sensor

GY-271 QMC5883L 3-Axis Electronic Compass Module Magnetic Field Sensor
The GY-271 QMC5883L 3-Axis Electronic Compass Module is a compact magnetic field sensor designed for precise heading and orientation detection. Ideal for low-field magnetic sensing applications, this module features a digital interface and is commonly used in projects like UAVs (unmanned aerial vehicles) and robotic navigation systems.
While the GY-271 is typically equipped with the HMC5883L sensor, some boards may feature the QMC5883L, which offers similar functionality but is not directly compatible with the HMC5883L. This sensor converts magnetic field data into a differential voltage output across three axes. The voltage change serves as the raw digital output, which can then be processed to calculate headings or detect magnetic fields from various directions.
If you are using a GY-271 board and notice an I2C address of 0x0C and only receive zeros in response, it’s likely that the board contains a QMC5883L chip instead of the HMC5883L.

GY-9833 AD9833 Programmable Sine Square Wave DDS Signal Generator
-15%
Basic Electronic Components, Electronic ComponentsGY-9833 AD9833 Programmable Sine Square Wave DDS Signal Generator
The AD9833 is a low power, programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed.
The AD9833 has a standard serial interface that allows the part to interface directly with several microprocessors. The device uses an external serial clock to write the data or control information into the device.
The AD9833 is written to via a 3-wire serial interface. This serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates with a power supply from 2.3 V to 5.5 V.
The AD9833 has a power-down function (SLEEP). This allows sections of the device that are not being used to be powered down, thus minimizing the current consumption of the part, e.g., the DAC can be powered down when a clock output is being generated.
Features:
- Digitally programmable frequency and phase
- 12.65 mW power consumption at 3 V
- 0 MHz to 12.5 MHz output frequency range
- 28-bit resolution: 0.1 Hz at 25 MHz reference clock
- Sinusoidal, triangular, and square wave outputs
- 2.3 V to 5.5 V power supply
- No external components required
- 3-wire SPI interface
Package Includes:
1 x GY-9833 AD9833 Programmable Sine Square Wave DDS Signal Generator

HB100 Microwave Doppler Radar Wireless Motion Sensor Module
HB100 Microwave Doppler Radar Wireless Motion Sensor Module
The HB100 Miniature Microwave Motion Sensor is a module that uses X-Band Bi-Static Doppler technology to detect motion. It consists of a Dielectric Resonator Oscillator (DRO) and a pair of Microstrip patch antennas, which make it suitable for motion detection equipment.
This module can be used for various applications, such as alarms, motion detectors, lighting control, vehicle speed measurement, and automatic doors.
Doppler Principle
The text below explains the Doppler effect based on time. When radio waves encounter a moving object, they will be reflected by the object. The frequency of the reflected waves will change depending on the motion of the object. If the radio waves encounter a stationary object, then the frequency of the reflected waves will be equal to the frequency of the transmitted waves. If the object moves towards the source, then the reflected waves will be compressed, which will increase their frequency. On the other hand, if the object moves away from the source, then the reflected waves will be stretched, which will decrease their frequency.
