Enhance your distance measurement projects with this high-precision Ultrasonic Ranging Module, designed to deliver accurate and reliable results using advanced ultrasonic ranging technology. Compatible and fully interchangeable with popular modules like SRF05 and SRF02, this module offers superior performance with a minimal blind zone of only 2cm and a sensing angle of up to 15°, making it ideal for a wide range of applications including robotics, obstacle avoidance, and security systems. Key Features: · Accurate Ultrasonic Distance Measurement: Utilizes ultrasonic pulses to measure distances with high precision, achieving an accuracy of ±0.3cm over a range of 2cm to 450cm. · Ultra-Close Detection Capability: Features a super close blind zone of just 2cm, enabling precise measurement even at very short distances. · Stable and Reliable Performance: Engineered for consistent operation with low static current consumption (<2mA) to ensure energy efficiency and long-lasting use. · Broad Compatibility: Fully compatible with GH-311 anti-theft modules and other similar systems, offering flexible integration options. · Easy Integration and Wiring: Simple control interface with VCC, trig (control terminal), echo (reception terminal), out (empty), and GND pins for straightforward connection and operation. · Compact and Efficient: Operates on a 5V DC supply and supports quick measurement cycles through IO-triggered ultrasonic pulse emission and echo detection. Specifications: · Operating Voltage: DC 5V · Static Current: < 2mA · Output Level: High 5V / Low 0V · Sensing Angle: ≤ 15° · Detecting Distance: 2cm - 450cm · Measurement Accuracy: ±0.3cm · Wiring Terminals: VCC, trig (control terminal), echo (reception terminal), out (empty), GND Module Working Principle: By applying a minimum 10µs high-level trigger signal to the control terminal, the module emits a series of eight 40kHz ultrasonic pulses and listens for their echoes. The output pin provides a high-level signal whose duration corresponds to the time taken for the ultrasonic waves to travel to the target and back, enabling precise distance calculation using the speed of sound (340 m/s). Package Includes: · 5 x Ultrasonic Ranging Modules Note: For optimal performance, ensure the module is connected before power is applied to avoid misoperation. The trig pin contains an internal 10K pull-up resistor and requires a 10µs or longer pulse from the microcontroller for triggering. The out pin is reserved for anti-theft module functionality and is unused in distance measurement mode. This Ultrasonic Ranging Module is a dependable and easy-to-use solution for anyone seeking precise distance sensing capabilities in embedded systems, automation, and robotics.
