|
 |
Specifications:
 |
Circuit board dimensions are 0.8" by 0.4" by 0.1"
|
 |
Recommended Vdd is 2.4 to 3.6 VDC (So works fine
with Propeller's Vdd=3.3 VDC) |
 |
Output is open-drain with a 100k pullup resistor to Vdd.
 |
Output goes low when object detected |
|
|
 |
Only $5.99 with free shipping and comes with free servo
extension cable.
 |
|
 |
If you cut the extension cable in half, you can solder
the wires to Prox1 |
|
 |
Example Usage:
 |
We've used 4 Prox1 sensors on the front of this robot
for object detection and floor detection. Can also be used as line
follower. (Note: Even though they are made for 3.3 VDC, this
robot is using them at 5 VDC without problem). |
