YW101: ON/OFF Motion Sensor

Arduino Zero Crossing Microwave Movement Detector

Zero-crossing point operation helps protect the microwave motion sensor against in-rush current. It is a algorithm designed to detect the point where a signal waveform crosses the zero voltage axis. This point is where the signal changes polarity from positive to negative or vice versa.

>> B2B Hardware Engineering & Customization

The Arduino-compatible zero-crossing microwave movement detector is an industrial-grade, high-precision embedded hardware module engineered explicitly for IoT developers, firmware engineers, and smart appliance OEMs. By fusing advanced **high-frequency microwave Doppler radar principles** with an integrated, robust **zero-crossing detection circuit**, this breakout board allows mikrocontrollers to switch AC inductive and capacitive lighting loads precisely at completely eliminating catastrophic inrush currents and extending switching relay lifespans substantially.

* **Hardware-Level Zero-Crossing Protection:** Embedded with a high-speed zero-cross monitoring pipeline that detects the exact phase inversion point of the AC power line. By shifting the relay or TRIAC trigger point precisely to the zero-voltage node, it achieves absolute **arcing prevention**, shielding your connected smart building infrastructure from localized EMI noise and circuit degradation.

* **Flawless Arduino & MCU Ecosystem Integration:** Fully optimized for seamless deployment across open-source electronics architectures. Featuring a standardized **3.3V / 5V TTL compatible digital I/O interface**, the module pairs effortlessly with Arduino Uno, Mega, ESP32, Raspberry Pi Pico, and standard STM32 industrial platforms without requiring external logic level shifters.

* **Advanced Microwave Doppler Signal Processing:** Operates far beyond the constraints of legacy PIR sensors. The onboard radar hardware emits continuous high-frequency waves, tracking localized frequency shifts to detect macro and sub-millimeter human micro-motions even through non-metallic walls, enclosures, and architectural wooden panels.

* **Onboard Potentiometer Calibration:** Equipped with precision, multi-turn miniature trimmers allowing developers to adjust detection sensitivity thresholds and output hold-time delays directly on the PCB, minimizing firmware overhead during early-stage prototyping.
