Document No: SJ-GU-TF02-02 Version: A00 1. Product Overview The product is based upon ToF (Time of Flight), supplemented by particular optics, electricity, and design, so as to measure distance with stability, precision, high sensitivity, and high speed.
Document No: SJ-GU-TF02-02 Version: A00 Signal Acceptance Semi-angle β Semi-angle of LiDAR’s effective detection 1.
Document No: SJ-GU-TF02-02 Version: A00 Grade VI of IP dust proof represents the full prevention from intruding by foreign object and dust. Grade V of IP dust water represents the prevention from damaging the electrical appliance by the intrusion of water from the nozzle at different directions. TF02 protection grade can ensure its normal operation under light rain, moderate rain, pesticide spraying by drone and polluted optical windows.

Document No: SJ-GU-TF02-02 Version: A00 The data output by TF02 is shown as below. All the data are hexadecimal. Each frame of data totals 9 bytes. The data contains distance information, i.e. Dist; signal strength information, i.e. STRENGTH; and reliability information, i.e. SIG. The frame end is data parity bit.
Document No: SJ-GU-TF02-02 Version: A00 Byte2 STRENGTH_H STRENGTH high 8 Bits Byte3 STRENGTH_L STRENGTH low 8 Bits Byte4 TIME Exposure time is divided into two levels and expressed by 0x03 and 0x06 respectively. The greater the value is, the longer the exposure time is Reliability is divided into 8 levels, respectively indicated by 0x01-0x08. Byte5 SIG When the reliability level is 7 or 8, it means data is reliable.
