DISCONTINUED

REPLACED BY: DFRobot High Power Ultrasonic Range Finder V2.0 (SKU:SEN0003)

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

• Power Supply: Internal voltage regulator circuit with wide operating voltage 6V-24V
• 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
