Picture of productUltrasonic Range Finder SRF04



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. Manufacturer: DV. Manufacturer's Part Number: SRF04.

  • Simplifies direction by resolving magnetic field measurements into two components axes.
  • 8-bit angular resolution +/- 1 brad after calibration.
  • Only 30 to 40 ms between start measurement and data-ready with simple synchronous serial interface.
  • Built-in resistor protection for data pins eliminates bus conflict risks.
  • Compact and breadboard-friendly 0.3 inch, 6-pin DIP package.

Application Ideas:
  • Mobile and walking robot direction sensor
  • Handheld electronic compass
  • Weathervane indicator for remote weather stations

 QTI Line Follower AppKit for the Boe-Bot
from Parallax




This add-on kit uses QTI infrared emitter/receiver modules to easily enhance the line following capability of your Boe-Bot robot. The QTI sensors mount underneath the front of the Boe-Bot chassis, and can be positioned to adjust to different width lines. The application in this kit uses three QTI sensor/mounting hardware sets, arranged to follow 3/4-inch black electrical tape on white poster board. As a bonus, we have added a fourth sensor/hardware set. Once you master the basics, use all 4 QTI sensors together to make your own custom applications. Learning to use the QTI is easy with these illustrated instructions and example BASIC Stamp code written by Andy Lindsay, author of Robotics with the Boe-Bot.

This kit includes all the circuit and sensor hardware you need to add QTIs to your Boe-Bot:
  • (4) 10 k 1/4 watt resistors
  • (4) 3-pin male-male headers
  • (4) QTI sensor modules
  • (4) 3/8" 4-40 pan-head screws
  • (4) nylon washers
  • (4) 1" round standoffs
  • (4) 7/8 inch 4-40 pan-head screws
  • (4) inch round spacers
  • (2) bags of 10 3" jumper wires
  • (4) 10 inch servo cable extenders
  • Printed 6-page documentation (view it below)


You will need to supply your own Boe-Bot, white poster board, and black electrical tape. Manufacturer: Parallax. Manufacturer's Part Number: 28108.

 SHT11 Temperature and Humidity Sensor Module
from Parallax




When it comes to precision temperature and humidity measurement, Sensirion has simplified the process their SHT1x sensor series. Through a two-wire serial interface, both temperature and humidity can be read with excellent response time and accuracy. Parallax has simplified the use of the SHT11 by mounting it in a user-friendly 8-pin DIP module. The module includes a data-line pull-up and series limiter making it possible to connect directly to the BASIC or Javelin Stamp.

Features:

  • Temperature range: -40 F (-40 C) to +254.9 F (+123.8 C)
  • Temp. accuracy: +/- 0.5 C @ 25 C<
  • Humidity range: 0 to 100% RH
  • Absolute RH accuracy: +/- 3.5% RH
Manufacturer: Parallax. Manufacturer's Part Number: 28018.

 Thermocouple Kit
from Parallax




Thermocouples provide a low-cost, reliable means of measuring temperature over a wide range. Interpreting thermocouple output can be challenging because of the very low Seebeck output voltage (fractional to low millivolts) and the need to provide cold junction temperature compensation. The Parallax Thermocouple Module uses the Dallas/Maxim DS2760 High Precision Li+ Battery Monitor IC to process the thermocouple output. The Thermocouple Module has the following features:
  • 1-Wire interface allows multiple devices with just one BASIC Stamp I/O pin
  • Cold Junction measurement: 0C to +127C (0.125C resolution)
  • Low power consumption: Active current = 90 A max, Sleep current: 2 A max

In addition to the interface module, the kit includes 3 Thermocouple elements: K-type (Chromel / Alumel), J-type (Iron / Constantan), and T-type (Copper / Constantan). This kit is ideally suited to work with a BASIC Stamp BS2P24, BS2P40 or BS2PE. Manufacturer: Parallax. Manufacturer's Part Number: 28022.

 Twinkle Toes Touch Sensor for Toddler
from Parallax




These optional bumper sensors (called "Twinkle Toes" in the Advanced Robotics text that comes with Toddler) detect low-lying objects which are not seen by the infrared sensors. Bi-color LEDs glow green for "path clear" and red when the sensors detect an object.

The kit includes two toes, extra pieces of wire so you can experiment with custom bumper designs, mounting hardware and two 12" cables for an easy connection to Toddler's BASIC Stamp board. Manufacturer: Parallax. Manufacturer's Part Number: 27312.
