Hello,
I’m trying to make an autonomous robot and I want to give it some sort of proximity sensor, for obstacle detection and if someone comes close to it. However, I want to have a wider field of view, like the width they show off for car sensor diagrams, as opposed to something like an HC-SR04 or other sort of linear sensor.
I can see that the MAXSONAR-EZ0 seem to have wider FOV, but any sort of example I see online uses them in a similar fashion to the HC-SR04. Are there any hobbyist level sensors or do the high cost industries have all the fun?
Regards,

Hello @Confusedgineer and welcome to the forum,
However, I want to have a wider field of view, like the width they show off for car sensor diagrams, as opposed to something like an HC-SR04 or other sort of linear sensor.
Cars usually use LIDARs which are more accurate than ultrasonic sensors or IR SHARP sensors and feature a wider field of view. Some LIDARs only feature a single beam, some are multibeam and some rotate in order to map the surrounding area, but they are pricier than the regular hobbyist level sensors. Some manufacturers offer some cheaper models perfect for hobby robotics, although they might be still considered expensive.
A good alternative could be using PIR sensors, which are not so accurate but are definitely much cheaper and could work for your project depending on the tasks you want to achieve.
I hope that helps!
Hi @geraldinebc15 ,
Yeah, I’m trying to avoid LIDAR because of the cost (and large data stream). I’ll try my luck with reading up on and trying out PIR sensors.
Thank you for the reply!
