## Description

TF02-i LiDAR is an industrial-grade medium-range distance sensor. Its maximum detection range can reach up to 40m and it has an adjustable frame rate with a maximum of 1KHz.This rangefinder has a PC/ABS/PMMA enclosure with IP65 water and dust resistance. It supports a wide range of input voltages (7-30V) with reverse protection to protect the internal circuit and adopts RS485 communication interface and standard Modbus protocol. Multiple built-in operating modes are included for the users to change their parameters and configurations to meet different applications. The TF02-i LiDAR can be used on the Arduino UNOR3 through the TTL to RS485 Shield, and it can also be used on the Raspberry Pi through the USB to RS485 module. Those two ways provided by DFRobot can make TF02-i LiDAR simpler to be used.How does TF02-i LIDAR work?TF02-i is a single point LiDAR, which is based on Pulse Time of Flight (PTOF).It adopts an incoherent energy receiving mode, and the detection is mainly based on Pulse counting. TF02-i emits a narrow pulse laser, which is collimated by the transmitting lens to form a collimated light,which enters the receiving system after being reflected by the measured target and is focused on the APD detector by the receiving lens. The time between the transmitted signal and the received signal is calculatedthrough the circuit amplification and filtering, and the distance between TF02-i and the measured target can be calculated through the speed of light.Pinout Diagram ApplicationSELECTION GUIDE Parameters TFmini-i LiDAR TF02-i LiDAR Product Performance Operating Range 0.1-12m@90% reflectivity 0.1-40m@90% reflectivity 0.1-7m@10% reflectivity 0.1-13.5m@10% reflectivity 0.1-12m@90% reflectivity&70Klux 0.1-40m@90% reflectivity&100Klux 0.1-7m@10% reflectivity&70Klux 0.1-13.5m@10% reflectivity&100Klux Accuracy ±6cm (0.1~6m), ±1% (6~12m) ±5cm (0.1~5m), ±1% (5~40m) Distance resolution 1cm 1cm Frame rate 100Hz 100Hz Ambient light immunity 70Klux 100Klux Operating temperature -20~60°C -20~60°C Enclosure rating IP65 IP65 Optical Parameters Light source VCSEL VCSEL Central wavelength 850nm 850nm Photobiological safety Class1 (EN60825) Class1 (EN60825) FOV (Field of view) 2° 3° Electrical Parameters Supply voltage 7~30V 7~30V Average current ≤65mA@12V ≤70mA@12V Power consumption ≤0.8W@12V ≤0.85W@12V peak current 100mA 100mA Others Communication interface RS-485 RS-485 Dimensions 50mm*34mm*41mm (L*W*H) 69mmx41.5mmx31.5mm (L*W*H) Enclosure material PC/ABS/PMMA PC/ABS/PMMA Storage temperature -30~75°C -30~80°C Weight Weight 52g Weight 60g(with cable) Cable length 70cm 70cm FeaturesWide range of input voltages (7-30V) with reverse protectionRS485 interface communicationAdjustable frame rate with a maximum of 1KHzMedium range detection (0.1 to 40m)IP65 protection for industrial application Compatible with Arduino UNO R3 and Raspberry PiApplicationsDetection of vehicle and pedestrian Vehicle collision avoidance and safety warning systemsUAV assisted takeoff and landingAltimeterSpecificationProduct PerformanceOperating Range:      0.1-40m@90% reflectivity       0.1-13.5m@10% reflectivity       0.1-40m@90% reflectivity & 100Klux       0.1-13.5m@10% reflectivity & 100Klux Accuracy: ±5cm (0.1~5m), ±1% (5~40m)Distance resolution: 1cmFrame rate: 100HzAmbient light immunity: 100KluxOperating temperature: -20~60°CRepeatability: 1σ:<2cm(0.1~35m@90% reflectivity)Enclosure rating: IP65Optical Parameters Light source: VCSELCentral wavelength: 850nmPhotobiological safety: Class1 (EN60825) FOV (Field of view): 3°Electrical Parameters Supply voltage: 7~30VAverage current: ≤70mA@12VPower consumption: ≤0.85W@12Vpeak current: 100mAOthersCommunication interface: RS-485Dimensions: 69mmx41.5mmx31.5mm (L*W*H)Enclosure material: PC/ABS/PMMAStorage tempe rature: -30~80°CWeight: 60g (with cable)Cable length: 70cmDocumentsProduct wikiSoftware: Arduino IDEShipping ListTF02-i LiDAR Laser Range Sensor (40m) x1
