Hi. I bought a Sparkfun A111 radar and was hoping to use it with an Arduino but have now realised it is not going to work - or at least there are not any Arduino libraries.
My aim is to make a ground proximity detector for a light aircraft. I am only looking for at least 2m measure distance. Since it has to measure the distance to the ground at about 100kph over variable (grass, bitumen, dirt) surfaces in daylight I suspect Lidar may not be reliable.
(And don’t worry - this is not a critical flight control or life dependent function … just a non-critical guide to landing height.)
It looks like your SEN0306 - 24GHz Microwave Radar Sensor - might do the job, but it is getting expensive (on top of the A111 board I can’t use …)
So can you please advise - as far as possible and to your best guess:
- Confirm there are no Arduino libraries for the A111?
- Do you think Lidar like SEN-15179 - the TFmini plus would reliably detect the ground as i need. (1-2 meters, 100kph, daylight, variable surface)
- Do you think the SEN0306 would work well for me?
Thanks in advance.
