Operating voltage: DC 5V Static current: <2mA Detection distance: 2–450 cm Type: Ultrasonic distance measuring module Compatibility: Compatible with SRF05, SRF02 and other comparable ultrasonic distance modules Performance: Stable operation with accurate distance measurement Key benefits Accurate distance readings across a wide range (2–450 cm) for reliable sensing and measurement. Low idle power draw (<2mA) helps reduce overall system power consumption in battery-powered projects. Simple 5V operation makes integration easy with common microcontrollers and development boards. Stable performance minimizes false readings and improves repeatability in real-world conditions. Interchangeable with SRF05, SRF02 and similar modules, simplifying upgrades or replacements. What this module does Emits ultrasonic pulses and measures the time until echoes return to calculate distance to an object. Provides a straightforward, low-power way to add proximity or range sensing to electronic systems. Who needs this Hobbyists and engineers building robots, drones, or automation systems that require dependable short- to mid-range distance sensing. Developers who need a compact, compatible sensor module that works with existing SRF05/SRF02 designs. Projects where power efficiency and measurement stability are important. Practical applications Mobile robotics: Obstacle detection and avoidance for small robots operating in indoor environments. Vehicle parking or proximity aids: Short-range distance sensing for parking assistance or proximity warnings. Level sensing and automation: Non-contact detection for liquid level monitoring or item presence on conveyors. Why it stands out Wide detection range (2–450 cm) covers common short- and mid-range sensing needs. Low static current and single supply voltage (DC 5V) make it suitable for embedded and battery-powered designs. Compatibility with SRF05 and SRF02 ensures easy substitution or integration into existing systems. Notes on integration Operates from a DC 5V supply. Expect best performance when mounted with a clear forward path unobstructed by surrounding surfaces. Designed as a drop-in ultrasonic distance measuring module compatible with commonly used SRF05/SRF02 interfaces.
