Would LIDAR-Lite 3 be useful for measuring the distance to the car behind?
Will it be confused by the road moving beneath?
Is the range of 40m also outdoor in sunlight?
I plan to use this in combination with a GPS to measure speed, to make a “You are too close!” sign flash at the rear of my car.
(People don’t carry guns, and road rage is very rare here, so I’ll take the risk…)
Hi,
Yes, it may work.
Please note that most cars’ front are rounded and made of materials that may not reflect the signal properly. Therefore, you may not get great readings in all cases.
Sunlight will certainly affect the measurements but should not be too bad since this sensor uses the signal’s signature over hundreds of readings to produce one measurement, not simply time of flight (like most other sensors). This will help with working in sunlight. You may want to try and aim it at something reflective, like a licence plate (if cars where you are have them in front), since these are normally flat, perpendicular to the road and made to be reflective to IR.
Also, for your GPS needs, you may be interested in products we carry here.
For a display, this one may fit your needs. If you provide enough current to the display it can be quite bright.
We hope this helps!
Sincerely,
