| If you are looking for Range Finder, to measure the distance then here is Parallax's PING)))™ ultrasonic sensor, which is perfect for varies applications that require you to perform measurements between moving or stationary objects. |
Applicable in:
• Robotics
• Security systems or as an infrared replacement
How..?
- Through sonar Ping sensor measures distance
- An ultrasonic (above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return.
- Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target.
Features:
- Provides precise, non-contact distance measurements within a 2 cm to 3 m range
- Simple pulse in/pulse out communication
- Burst indicator LED shows measurement in progress
- 20 mA power cosumption
- Narrow acceptance angle
- 3-pin header makes it easy to connect using a servo extension cable, no soldering required
Key Specifications:
- Power requirements: +5 VDC
- Communication:Positive TTL pulse
- Dimensions: 0.81 x 1.8 x 0.6 in (22 x 46 x 16 mm)
- Operating temp range: +32 to +158 °F (0 to +70 °C)
