Microwave Doppler Radar Motion Sensor for 10.525GHz

Radar is what the military relies on for object and motion detection, as it is one of the most reliable methods available. This technology can be leveraged in your next project by integrating it with your Android device or microcontroller. The HB100 Microwave Doppler Radar Wireless Module Motion Sensor is a versatile option that offers a range of features and benefits.

Features: - Compact size: 37mm x 45mm x 8mm - Operating voltage: DC 5V - Non-contact detection - Reliable performance regardless of temperature, humidity, noise, air, dust, or lighting conditions, making it suitable for harsh environments - Immunity to radio frequency (RF) interference - Low power consumption, with only 40mA of input power required - Detection range of more than 20 meters

Compared to sonar or infrared detection commonly used in robotics, the HB100 provides a more accurate and efficient solution. Its sensor can be discreetly integrated, ensuring reliable performance even when hidden.

The package includes two HB100 Microwave Doppler Radar Wireless Module Motion Sensors, each operating at a frequency of 10.525GHz. This microwave frequency offers several advantages:

1. The microwave antenna has good directionality during transmission, allowing for easy control of the probe's range.
2. Microwaves are more susceptible to attenuation, absorption, and reflection during transmission, making them less affected by interference from walls and other obstructions outside the target object.

The HB100 can be powered in two modes: continuous direct current (CW) mode and pulsed power (PW) mode. In CW mode, the typical current consumption is 35mA. In PW mode, the recommended power supply is a 5V pulse with a width between 5μs and 30μs (typically 20μs) and a frequency between 2 and 4kHz (typically 2.0kHz). The average current consumption in this mode is 1.2mA to 4mA, with a 3-10% duty cycle.

The RF output of the HB100 is designed to be safe for human exposure. In CW mode, the total output power is less than 15mW, with a power density of 1mW/cm^2 at 5mm and 0.72μW/cm^2 at 1m. In a 5% duty cycle PW mode, the power density is reduced to 50μW/cm^2 and 0.036μW/cm^2, respectively.

The IF (Intermediate Frequency) output of the HB100 provides a linear relationship between the object's radial velocity and the output frequency. When an object moves radially at 1m/s relative to the antenna surface, the IF output frequency is 72Hz/s.

In conclusion, the HB100 Microwave Doppler Radar Wireless Module Motion Sensor offers a reliable and versatile solution for motion detection, making it a valuable component for various applications, including robotics and automation projects.
