I am searching for a solution for detecting "Reverse" for vehicle video-recorder(black box).
Could you let me know which is the best part of it?
Solved! Go to Solution.
I'm not able to get your point here.
Can you give me more detail what you are looking for?
Do you want to find a solution to decoding the black box for vehicle video recording box?
Or you want to find a solution to detect the motion of the car then trigger vieo recording?
Sorry about that.
I'm looking for a part to detect the reverse direction. For example, when I drive a car, I believe the accelerometer or gyro can detect the forward and reverse direction.
So I want to know which is the best solution between acc and gyro for detecting the direction?
OK, now i understand. you want to detect the deceleration of vehicles.
I will say using IMU will be able to achieve this target.
The linear acceleration sensor can be used for this purpose which is sensor fusion of accel and gyro data.
