Description
The KEYESTUDIO KS0504 SR01 Ultrasonic Sensor V3 measures the distance between the module and a nearby object using 40 kHz ultrasonic pulses. It works with both 3.3 V and 5 V controller logic, making it useful for Arduino-compatible boards and many other microcontroller projects.
With a maximum sensing range of 3 m and a blind zone below 4 cm, the module suits robot obstacle detection, distance measurement and interactive electronics. A familiar four-pin trigger-and-echo interface keeps integration straightforward.
Why you’ll love it
- Correct V3 hardware: Uses the CS100A-based KS0504 design rather than the older SR01 V2 module.
- 3.3 V and 5 V support: Connects to a wider range of development boards.
- Up to 3 m range: Covers common robot and benchtop distance-sensing tasks.
- Simple digital interface: Uses standard trigger and echo signals.
- Compact module: Measures 49 × 22 × 19 mm for easy project integration.
