What are the different types of remote sensors?

Remote sensors can be categorized into two main types: active and passive sensors. Active sensors emit their own energy, such as radar and LiDAR, to detect objects and measure distances. Passive sensors, on the other hand, detect natural energy reflected or emitted from objects, such as sunlight, and include technologies like multi-spectral and thermal imaging. Additionally, remote sensors can be classified based on their platform, such as satellite, aerial, or ground-based systems.
