For now, DFRobot has launched several solid state LiDARs, but how should we choose the most suitable one? Hereafter, the reference guide is released. It introduces and lists all features of them.

 

1. TF Mini LiDAR (ToF) Laser Range Sensor

TF Mini LiDAR (ToF) Solid State LiDAR Range Sensor

DE-LIDAR TF02 is a unidirectional laser rangefinder, which is based on ToF (Time of Flight) technology. TF Mini's maximum detection distance is 12 meters. TF Mini also supports 100Hz sampling resolution, within 6 meters, its accuracy is within 4cm, 6~12 meters, and accuracy is within 6 cm. FOV of 2.3 degrees. Its anti-interference is strong and can work in outdoor light, the anti-ambient light power is 70Klux; the overall weight is 4.7g. Small size, convenient to install and use.

But it may be invalid when probing objects with high reflectivities, such as mirrors and smooth tiles. When there are transparent objects, such as glass and water, between the product and the tested object, it may become invalid.

The laser sensor can be used as a distance-measuring tool to detect the distance from it to obstacles. It can also be used as an eye of a robot; it provides distance information for robotic safe avoidance and route selection. It supports system automation in a variety of machine control scenarios. Because of its small size, lightweight, and low power consumption, it is also suitable for altitude-hold quad-copters and terrain following.

 

2. TF Mini Plus (ToF) Laser Range Sensor

TF Mini Plus (ToF) Solid State LiDAR Sensor

Inherited characters of low cost, small size, and low power consumption from TFmini, TFmini Plus has greatly improved its whole performance—increasing the frame rate from 100Hz to 1000Hz, reducing the blind zone to 10cm, and improving accuracy and stability. What’s more, TFmini Plus introduces IP65 enclosures that could effectively prevent water and dust, which also makes the product more adaptable to outdoor light or environments with different temperatures and reflectance. The sensor can provide much lower power consumption and a more flexible detecting frequency. It is compatible with UART and IIC communication (send command to switch) and adopts a standard 5V power supply. The average power is 0.55W.

We can use the sensor to detect the distance between it and the obstacle ahead and use it as an eye of a robot to provide distance information for the robot to safely avoid obstacle and select the route, or apply it in Automotive Collision Avoidance System. It is also suitable for the altitude holding systems of UAV and UAV landing scenarios.

 

3. DE-LIDAR TF02 (ToF) Laser Rangefinder (22m)

DE-LIDAR TF02 (ToF) Solid State LiDAR (22m)

DE-LIDAR TF02 is a newly developed product based on the widespread application experience of TF01. It is a unidirectional laser rangefinder, which is based on ToF (Time of Flight) technology.

It can work under 100K lux light without interference from the temperature, humidity, light, electronics, and airflow. High sensitivity, measuring distance up to 22 meters, accuracy in cm level. Scanning frequency up to 100Hz, real-time detection of distance with a 100 times/second refresh rate for more accurate data. The protection design of the TF 02 is based on the IP 65 level, which prevents it from dust, water, and corrosion.

DE-LIDAR TF02 can be widely applied to UAV altitude setting, automatic terrain following (ATF), machine control, safety devices, distance monitors, smart parking lots, materials monitor and so on.

 

4. TF03 (ToF) Laser Range Sensor (100m)

TF03 (ToF) Solid State LiDAR (100m)

TF03 is the third generation of the TF series, containing two versions: 100m and 180m. As a long-distance LiDAR in accordance with the industrial level, TF03 inherits the cost-effective and compact-integration advantages from the previous two generations. Meanwhile, TF03 upgrades more than ten key parameters and offers multiple expansion functions to meet the various demands in different application scenarios.

TF03 employs the pulsed time-of-flight principle. The unique design of the optical system and the signal processing circuit improved the detecting performance in a compact size. With a small size of 44*42.9*31.8mm, it can be covered by just the palm of one hand. In addition to increasing the range to more than 100 meters, this sensor features a 0.1m blind zone, ±10cm accuracy, up to 10KHz frequency, and 100Klux ambient light immunity. TF03 also contains a compensation algorithm targeting outdoor highlight environments, so that it can still keep excellent performance in harsh environments.

The shell of TF03 is made of aluminum alloy and infrared band-pass glass to improve the overall strength. With IP67 enclosure rate, the sensor can be applied in various extreme environments. It supports multiple interfaces for different applications, such as UART, CAN, and IO. Besides that, multiple parameters of TF03 can be configured by customers, including the measuring frequency, baud rate, trigger mode, over-range assignment, and so on. TF03 is also equipped with the BootLoader function, enabling users to upgrade product firmware locally. Power the sensor with 5V. The average power consumption is 0.55W.

TF03 is applicable to the terrain following drones, the collision avoidance of cars, intelligent transportation, and industrial safety warning.
