URM05 High Power Ultrasonic Range Finder
Overview
- Range: up to 10m
- Direction angle 15° (-6dB)
- Operating temperature range: 0°C ~ + 40°C
- Operating voltage: 6V-24V
The DFRobot URM05 High Power Ultrasonic Range Finder is based on electrostatic senscomp's 6500 ultrasound transducer design. It can measure a distances of up to 10m. The angle between the ultrasound probes is only 15 °, while the majority of the ultrasound is 60 °.
Features

- Current: normal current 55mA, when sending the instant the current is 2A
- Operating temperature range: 0°C ~ + 40°C
- Interface: TTL level pulse
- Operating frequency 49.5KHZ. Probe direction angle 15 ° (-6dB)
- Ultrasonic Distance Measurement: 15 cm to 10.5 m
- Operating modes: single-echo mode and multi-echo mode
- Module Size: diameter 43mm, height 24mm
- Module Weight: About 19g
