Ultrasonic Sensors


Picture of product
Ping Bracket Kit from Parallax



With this information you can effectively navigate the path with few obstructions, or hone in on an object you would like follow.

Parallax offers this kit for a very low price to encourage robot enthusiasts to experiment with our Ping))) ultrasonic sensor. For the price of what many companies sell a Futaba S148 servo were providing the complete kit with free technical support. Download the documentation to review the parts included in this kit.

With the purchase of a few additional components identified in the documentation for this product you can also mount a HM55B Compass Module on the same bracket.

This kit does not include the Ping Ultrasonic Range Finder Catalog number: 2952. Brand: Parallax. Brand's Part Number: 570-28015.

Ultrasonic Range Finder SRF05 from Robot Electronics



This SRF04 is the most popular sonar sensor for use in hobby robots. It transmits an ultrasonic "ping" when instructed by your program and returns a signal when it receives an echo. Your program determines distance by timing the interval between signals. Its overall range is approximately 1" to 9'. It can detect a 1" diameter broom handle 6.5' or further away. This device works great for most "target avoidance" applications including most combat competitions. For simpler programming and greater control, consider the SFR08 sensor. Catalog number: 2262. Brand: Robot Electronics. Brand's Part Number: SRF05.

Ultrasonic Range Finder SRF08 (High Performance) from Robot Electronics



This is the smarter cousin of Devantech's popular SRF04 sonar sensor. It provides twice the sensing range of the SRF04 plus an on-board MCU which handles the critical timing functions and distance calculations. The SRF08 can report up to 17 echoes from each ping, allowing your robot to identify the shape of a target or identify an open doorway. Echoes can be reported as inches, centimeters or time of reflection. Its overall range is approximately 1" to 18'. Catalog number: 1053. Brand: Robot Electronics. Brand's Part Number: SRF08.

Picture of product
QTI Sensor from Parallax



The QTI Sensor is an infrared emitter/receiver that is able to differentiate between a dark surface) with low IR reflectivity) and a light surface (with high IR reflectivity). These little sensors can be very handy for line following, maze navigation, or sensing the outer rim of a SumoBot ring. Wiring options allow it to be used digitally for fast black/white line following, or as an analog sensor to detect different shades of gray. A daylight filter is built into the sensor.

What does QTI stand for?
Q = Charge
T = Transfer
I = Infrared

When your microcontroller measures the time it takes for the QTI's capacitor to decay, it's measuring a rate of charge transfer through an infrared phototransistor. This rate indicates how much infrared is reflecting off a nearby surface. Catalog number: 4231. Brand: Parallax. Brand's Part Number: 555-27401.

Sharp GP2Y0A21YK IR Sensor - 31" / Analog



This is an integrated sensor with IR emitter, detector, optics and timing logic. Its output is an analog voltage proportional to the distance to the nearest object in its field of view. The output signal is compatible with low-cost ADC circuits including those built into many robot controllers. The sensor can detect objects within a range of approximately 5" (12cm) to 31" (80cm).".

The electrical connections to this sensor use an unusual miniature connector. We recommend that you order either Cable for Sharp 3-Pin IR Sensors or Cable for Sharp 3-Pin IR Sensors for Breadboarding with your sensor. Catalog number: 4177. Brand: Sharp. Brand's Part Number: GP2Y0A21YK0F.
