Description

  • Compact 48mm x 40mm x 20mm module with 40m measuring range
  • Signal Processing Improvements offer 5X Faster Measurement Speeds
  • Improved I2C Communications and assignable I2C Addressing
  • Great for drones, robotics and other demanding applications

The LIDAR-Lite 3 Laser Rangefinder by Garmin is an essential, powerful, scalable and economical laser based measurement solution supporting a wide variety of applications (ex. drones, general robotics, industrial sensing and more). Measures distance, velocity and signal strength of cooperative and non cooperative targets at distances from zero to more than 40 meters. Offering the highest performance available in a single beam ranging sensor in its class.

The new LIDAR-Lite has all of the same specifications as the legacy sensor:  Up to 40-meter range capability with 1cm resolution, small size, low power consumption and light weight.  There have been a number of upgrades:

Signal Processing Improvements offer 5X Faster Measurement Speeds

  • With the implementation of a new signal processing architecture, LIDAR-Lite will now operate at measurement speeds of up to 500 readings per second offering greater resolution for scanning applications.

Improved I2C Communications

  • LIDAR-Lite I2C communication will now operate at 100kbits/s or 400kbits/s. 
  • Now broadly compatible with the most basic of I2C drivers and most micro-controller boards.  Instead of “ack” and “nack” responses when the sensor is available or busy, a status register (0x01) can be queried to indicate sensor status. 
  • The previous measurement value can be read anytime during an acquisition until it is overwritten by a new value.  No need to wait for the sensor to become available to read data.  Just fire it up and let it rip!

User Assignable I2C Addressing 

  • Individual sensors can have a unique I2C address. 
  • The base address of 0x62 can be used as the default in single sensor applications and it will also be available in multi-sensor applications as a broadcast address to initiate a command to all the LIDAR-Lites on the I2C bus. 

Compatible with the Legacy Sensor in all primary functions 

  • Compatibility will extend into future versions and product variants, i.e. LED based sensor, long range or high rep rate products. 

Expanded Support and Documentation Team 

  • Application code improved and updated.  Many projects ready to run with only an Arduino and the sensor right out of the box.
  • Documentation expanded to support new functions

LIDAR-Lite 3 Laser Rangefinder

The combination of attributes found in the LIDAR-Lite - high performance, low cost, small size, light-weight, low power consumption, and dynamic configurability along with I2C communications and addressing - means that it becomes practical to install multiple sensors on a project with minimal weight and power penalties. The beam width of the LIDAR-Lite as delivered is .5°. This narrow beam provides long-range performance and also enables better target selectivity than an ultrasonic sensor.

LIDAR-Lite 3 Laser Rangefinder

The laser version of the PulsedLight LIDAR-Lite uses an edge emitting, 905nm, single stripe laser. This Laser Product is designated as Class 1 during all procedures of operation, however operating the sensor without its optics or housing or making modifications to the housing can result in direct exposure to laser radiation and the risk of permanent eye damage. Operating from a 5VDC power source and drawing only 100 milliamps peak power when taking a measurement and under 10 milliamps when idle, the LIDAR-Lite is ideally suited for projects running from battery sources where low power consumption is critical.

Technology innovations

  • The use of a signature matching technique (known as signal correlation) that estimates time delay by electronically sliding a stored transmit reference over the received signal in order to find the best match.
  • Operation of the infrared LED or laser in short bursts allowing a 100:1 advantage in peak output power over measurement systems using a continuous beam.
  • A novel current driver technology with nanosecond signal transition times at high peak currents to produce high power transmit burst sequences.

屋外では20mが限界

Arduino + I2C で使用。照明安定の室内では36m測れたこともあったが、晴れた屋外では20mが限界で、それ以上だとほぼエラー。40mを謳い文句にしているのに長距離では使えず残念。精度アップできるTipsがあるなら情報提供して欲しい。

Issues at short range

The following is from only testing it for less than an hour. I still need to do more work with it so reader beware... According to the Robotshop's website, this LIDAR's range is from 0-40 meters. Reading that I bought the LIDAR to test for both short/long range usage. Per the operations manual, the accuracy below 5m is about +-2 cm and above 5m is +- 10cm. I tested the LIDAR against a flat, white wall at a 90 degree angle (the best scenario) hooked up to an Arduino with a 680uF cap across the power and ground. You can use either i2c or pwm and I chose i2c mode of communications. I am seeing pretty good values at distances at 8m and below at +-5 cm which is acceptable for my needs. I did not need to test beyond 8m. For very close ranges things break down. At 75 cm it is still accurate but below that values will fluctuate. Below 25 cm the values are completely untrustworthy. The spec does have a disclaimer that says "nonlinearity below 1m". I was not sure what that meant but suspected that meant below 1m your values will not be very good. That appears to be the case here. I still need to do more testing such as hitting the wall at an angle and beam spread at greater distances. This sensor looks very good for longer distances but short ranges < 1m it might not be for you. If I find anything of interest in the coming week I will post more.
