TFmini-S Lidar Range Finder Sensor Module Single-Point Micro Ranging Module for Arduino for Raspberry Pi for Pixhawk 4.5-6V

Fmini-S Lidar Range Finder Sensor Module Single-Point Micro Ranging Module for Arduino for Raspberry Pi for Pixhawk 4.5-6VDescription:TFmini-S is the improved version of TFmini, it is a single-point micro ranging module and could be widely used in the integrated application of various drones, UAVs, Robots and industrial equipments. It is based on ToF (Time of Flight) principle and integrated with unique optical and electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance detection.Features:Operating Range : 0.1-12mMaximum operating range at 10% reflectivity : 5mApplicable voltage range : 4.5-6VAverage power consumption : 0.12WFOV : 2°Communication interface : UART/I2CElectromagnetic Compatibility(EMC):EN 55032 Class BBaud rate:115200Data bit:8Stop bit:1Parity bit:0Minimum resolution ratio : 5mmFrequency: 100Hz(1-1000Hz adjustable)Light source:VCSELWavelength:850nmOperating temperature : 20-60CLight sensitivity : 70,000luxAccuracy : 1% (less than 6m), 2% (6m-12m)Size : 42mm * 15mm * 16mmWeight : 6.1gCertification:CE,FCC,ROHSMajor Applications:Traffic MonitoringObstacle detectionLevel measurementSmart deviceSecurity and obstacle avoidanceDrone altitude holding and terrain followingMachine control and safety sensorsDistance measuring instrumentPackage Includes:1 X TFmini-S Lidar Range Finder Module2 X CableFAQQ1: Is TFmini-S available with 3.3V or other power supply voltage?A1: Sorry, it is not available for the time being. The Standard power supply of TFmini-S is 5V±0.1V. If you have any further requirement, please contact our sales person to consult a customization design matter.Q2: TFmini-S will heat up after operating for a while. Is it broken?A2: This is the normal operating condition of the product. The temperature of the chip and circuit board will slightly up after a continuous operation, which is a normal case.Q3: Can TFmini-S be connected with Arduino or Raspberry Pi for use?A3: Yes, it can. TFmini-S adopts serial communication protocol so that it can connect to any control board supporting serial port communication.Q:Hello, the manual helped me to understand a lot, but i have one question: how i calculate the checksum, if the checksum is over 265(for exampel I would to set a frame rate of 250hz) thank you for the fast help. ich love this device and i will give a good appraisal.A: This is hexadecimal, if the checksum is over 265, you just need the lower 8 bits.Q: I have the TFmini-S.I've read the manual and read it again and I still don't understand this part:0--standard datamode1--I/O,near highand far low2--I/O,near lowand far highCan you expand at all?A: 0 Standard mode is the factory default mode, it means continuous output mode1 and 2 are both high and low level output modes. For example, if the threshold is set to 5m, then mode 1 means if output below 5m is high level , above 5m is low level; mode2 means if output below 5m is low level , above 5m is high levelQ: Has anyone adapted this for use under water ? I was thinking if encapsulation in acrylic and seeing if it could distance underwater.A: This lidar sensor can not work underwater.
