Key Features:

• Voltage Range: Operates on a low power supply with a working voltage of DC 2.7-12V, making it ideal for battery-operated projects.
• Ultra-Low Power: The static power consumption is less than 0.1mA, ensuring minimal impact on your project's power budget.
• Immediate Response: Features a quick delay time of just 2 seconds after detecting motion, followed by a blocking time of 2 seconds to prevent repeated triggers.
• Trigger Mode: Offers a repeatable trigger mode, meaning it can detect continuous motion within its range.
• Wide Sensing Area: Provides a sensing range within a ≤100-degree cone angle and 3-5 meters distance, depending on the lens used, perfect for room-scale projects.
• Adaptable: Designed to function in various environmental conditions with a working temperature range from -20 to +60°C.
• Compact Design: With PCB dimensions of just 10mm*8mm, it's perfect for tight spaces or where discretion is required.
• Module Lens: Equipped with a small lens to focus the detected infrared radiation, enhancing the sensor's sensitivity and range.
