    LiDAR Sensors

    Imagine a magical tool for farmers that gives them super-detailed maps of their fields. That's exactly what LiDAR sensors do! These maps aren't just regular ones, though – they're in 3D, like a virtual model of the farm.

    Why is this so cool for farmers? 

    Well, these smart maps help in many ways. Firstly, they assist in figuring out the perfect amount of water needed for the crops. It's like giving the plants exactly the right amount to drink, not too little.

    But that's not all – these sensors can also spot when crops are feeling under the weather. They can detect diseases early on, like a superhero for plants. This means farmers can take action quickly to keep their crops healthy and happy.

    And here's the best part: with all this helpful information, farmers can boost how much food they can grow. 

    What are LiDAR sensors?

    LiDAR, which stands for Light Detection and Ranging, is a sensing technology that uses laser light to measure distances and create highly accurate, three-dimensional maps of the surroundings. LiDAR sensors emit laser pulses and then measure the time it takes for those pulses to bounce back after hitting objects in their path.

    How do LiDAR sensors work?

    • The LiDAR sensor emits laser pulses. These pulses are in the form of thousands of laser beams per second.
    • The laser pulses hit objects in the environment, such as buildings, trees, or the ground, and get reflected back towards the LiDAR sensor.
    • The sensor measures the time it takes for each laser pulse to return. 
    • The collected distance measurements are then used to create a precise, three-dimensional map of the surroundings.
