Picture of productParallax Laser Range Finder



the Parallax Laser Range Finder (LRF) Module is a distance-measuring instrument that uses laser technology to calculate the distance to a targeted object. The design uses a Propeller processor, CMOS camera, and laser diode to create a low-cost laser range finder. Distance to a targeted object is calculated by optical triangulation using simple trigonometry between the centroid of laser light, camera, and object. Catalog number: 45948. Brand: Parallax. Brand's Part Number: 28044.

Picture of productUltrasonic Range Finder SRF05



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: 22624.

The Memsic 2125 is a low cost, dual-axis thermal accelerometer capable of measuring dynamic acceleration (vibration) and static acceleration (gravity) with a range of 2 g. For integration into existing applications, the Memsic 2125 is electrically compatible with other popular accelerometers.

Some of the Memsic 2125's features:
  • Measure 0 to 2 g on either axis; less than 1 mg resolution
  • Fully temperature compensated over 0 to 70 C range
  • Simple, pulse output of g-force for X and Y axis
  • Analog output of temperature (TOut pin)
  • Low current operation: less than 4 mA at 5 vdc

A sampling of possible BASIC Stamp applications with the Memsic 2125 include:
  • Dual-axis tilt sensing for autonomous robotics applications
  • Single-axis rotational position sensing
  • Movement/Lack-of-movement sensing for alarm systems
  • R/C hobby projects such as autopilots

Mesmic provides the 2125 in a surface-mount format. Parallax mounts the circuit on a through-hole providing all I/O connections so it can easily be inserted on a breadboard or through-hole prototype area. Catalog number: 15818. Brand: Parallax. Brand's Part Number: 28017.

Picture of productPIR Sensor



he PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load. Dual output modes and a sensible design that performs within stated datasheet specifications are a few reasons over 100,000 units are in use around the world. Catalog number: 46458. Brand: Parallax. Brand's Part Number: 555-28027.
