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.   
Key Features: 
  High sensitivity, and able to measure as far as 22 meters   
  High speed measurement with a maximum sampling frequency of 100Hz 
  Excellent anti-ambient light usability (operable under 100kLux ambient light) 
  Protection grade: IP65 
  Anti-corrosive against pesticide 
  Small in size and light 
Major Applications: 
  Drone altitude holding and terrain following 
  Machine control and safety sensors   
  Range measuring instrument   
2.  Optical Principle 
TOF is short for Time of Flight. It refers to that a sensor emits modulated near infrared light, 
which reflects when objects are in the way. TOF then converts the distance away from the 
filmed scenery by calculating the time difference or phase difference between emission and 
reflection, thereby generating in-depth information.
