Sensors
Some commonly used sensors
- SRF02 & SRF05 - ultrasonic distance sensing modules from Devantech.
- Ping - ultrasonic distance sensing modules from Parallax
- QRB1114 - focused IR reflective sensor
- QRD1114 - unfocused IR reflective sensor (datasheet)
- GP2D12 - Sharp distance measuring sensor
- GP2Y0A21YK - similar to the GP2D12 but with twice the beam width (datasheet)
- CNB1302 - a very small unfocused IR reflective sensor (datasheet)
- QRE1113 - a very small unfocused IR reflective sensor. Available on a breakout board
These sensors can be ordered from Robotshop and HVWTech
Here are two sensor articles taken from the articles section of the ORE website.
- The Sharp GP2D02 IR Distance Sensor
- Interfacing and using the GP2D02, along with sweeping it back and forth so that you don't have to buy a bunch of the expensive little suckers.
(Note: The GP2D02 has been discontinued) - Ultrasonic Sensor - Build a ultrasonic sensor that outperforms the polaroid units.
