The new PING))) ultrasonic sensor is a popular solution for anyone who wants to measure the distance between any moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as a replacement for infrared sensing stations. The PING))) sensor measures distances using sound; an ultrasonic sound (well above human hearing) pulse is transmitted from the unit and is echoed back to the target. The distance from the sender to the target is determined by measuring the amount of time that was required for the echo return. Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target. The PING))) can be easily implemented into any design and requires only 5V, GND, and a single I/O line. Range - 2cm to 3.35m (~.8" to 11.3')
Supply Voltage: 5V +/-10% (Absolute: Minimum 4.5V, Maximum 6V). Supply Current: 30 mA typ; 35 mA max. 3-pin interface (power, ground, signal). 20 mA power consumption. Narrow acceptance angle. Simple pulse in / pulse out communication.
Indicator LED shows measurement in progress.

The SRF04 Ultra Sonic Ranger Module is a high quality ultra sonic range finder, which can easily be connected to many microcontroller's to measure/detect the presence of obstacles. Using a 5V supply and drawing from 30mA typical. to 50mA max. The SRF04 can be connected directly to many micros without the need for a separate power supply. The URG-04LX Scanning Laser Rangefinder is a small, affordable and accurate laser scanner that is perfect for robotic applications. The URG-04LX is able to report ranges from 20mm to 4m (1mm resolution) in a 240° arc (0.36° angular resolution). Its power consumption, 5V 500ma, allows it to be used on battery operated platforms. Provided with diagnostic software and sensor cable. URG-04LX Features: Class 1 infrared laser scanner. Light weight (160g). Ultra compact size (50 x 50 x 70mm). 240° area scanning range with 0.36° angular resolution. +/- 10mm accuracy. 10Hz scanning rate. Detectable range is 20mm to 4m. Low power consumption (2.5 Watts) allows for longer battery life in robotic application. 500mA at 5V. USB and Serial (RS-232) interfaces for maximum flexibility.
