SparkFun Distance Sensor Breakout 紅外線遠距離測距感測器模組 RFD77402 (支援 Qwiic 系統)

SparkFun Distance Sensor Breakout 紅外線遠距離測距感測器模組 突破採用Simblee的 RFD77402 3D ToF(飛行時間)傳感器模組 為您提供近距離最準確的測量。RFD77402 使用紅外VCSEL(垂直腔表面發射激光)模塊來測量反彈目標的時間。這可以實現低至兩米的低成本毫米讀數!為了更容易使用這個突破,所有的通信都是通過I 2 C 完全通過我們方便的 Qwiic 系統實現的。但是,如果您更喜歡使用麵包板,我們仍然會打出0.1英寸的間距引腳。

由於RFD77402 的 850nm VCSEL以及電子驅動器和光學接收器傳感器,這一突破非常適合從 100mm 到 2000mm 的距離測量,1D手勢識別,機器人應用中的障礙物檢測和避免等等!RFD77402採用I 2 C接口,支持直接8位尋址方案來訪問模塊用戶的寄存器組以及主要用於調試目的或特殊操作的附加16位間接尋址方案。

技術導覽

SparkFun Distance Sensor Breakout – RFD77402 (Qwiic)

The SparkFun Distance Sensor Breakout utilizes the RFD77402 3D ToF (Time of Flight) sensor module from Simblee to give you the most accurate measurements at short range. The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) module to measure the amount of time it takes to bounce off a target. This allows low-cost millimeter readings up to two meters! To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1″ spaced pins in case you prefer to use a breadboard.

Thanks to the RFD77402’s 850nm VCSEL and electronic driver and optical receiver sensor, this breakout is ideal for distance measurements ranging from 100mm to 2000mm, 1D gesture recognition, obstacle detection and avoidance in robotics applications, and more! The RFD77402 utilizes an I2C interface that supports a direct 8-bit addressing scheme to access the module user’s register set and an additional 16-bit indirect addressing scheme that is mainly used for debugging purpose or special operations.

 


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
