The LDS-01 is a 2D laser scanner capable of sensing 360 degrees that collects a set of data around the robot to use for SLAM (Simultaneous Localization and Mapping). It supports USB interface and is easy to install on a PC.
This is not your normal Passive Infrared (PIR) sensor! The SparkFun AK9753 Human Presence Sensor Breakout is a Qwiic-enabled, 4-channel Nondispersive Infrared (NDIR) sensor. Each channel has a different field of view, so not only can the AK9753 detect a human, but it can also tell which direction the person is moving. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1" spaced pins in case you prefer to use a breadboard.
The RPLIDAR A3M1 is the next generation of 360 degree 2D LIDARs. Each RPLIDAR A3 can take up to 16000 samples of laser ranging per second thanks to its high rotation speed. The on-board system can perform 2D 360° scans within a range of 25 meters in enhanced mode and 20 meters in outdoor mode. Additionally, the generated 2D point cloud data can be used in mapping, localization, and object/environment modeling!
You may be familiar with the classic HC-SR04 distance sensor, it is great for providing non-contact distance readings from 2cm to 400cm. This board improves on the classic by adding a Qwiic connector to it, so now you can communicate over I2C. If you prefer to bypass the Qwiic connector and I2 you can also access the Trigger and Echo pins which are broken out on the edge of the board.
This is the new, weather resistant, field-hardened WR from Maxbotix. The XL series of this sensor features higher resolution, longer range, higher power output and better calibration when compared to the LV version.
