Drones for Science: $500–$15,000 (Almost) — Sensors, Add-ons, and Real-World Use
Drones are now central to data collection in environmental science, conservation, archaeology, agriculture, disaster response, and urban planning. They enable researchers to gather high-resolution imagery, multispectral data, and thermal signatures over difficult terrain, all at a fraction of the cost of manned aircraft or satellite access.
That said, scientific funding is often limited. Fortunately, you don’t need a $20,000 drone to get scientifically valuable results. This guide covers sUAS systems spanning from $500 to $12,000 — highlighting models with sensor-rich payloads, mapping capabilities, and regulatory compliance suitable for scientific workflows.

Bonus: Add on sensors for scientific workflows!!!
TFS-20 Lidar Sensor 0.2-20m range
Is it possible to get LiDAR sensors on a drone for $40-80?!?! Well, maybe. With offerings like this from Amazon, the experimentation may be worth it if you’re working on a budget:
This unit plus into a RasberryPi via the I/O connection. The data gathered could be converted into a point cloud and stored on the Pi. We are currently testing this unit and will be reporting back with what we find.

WayPonDEV FHL-LD19 2D Lidar Sensor
Here is another option in the LiDAR sensors that appears to be a little more robust. This unit, and the one above, include access to the manufacturers SDK (software development kit/kernel) for installation and custom workflows. This unit is also currently being evaluated by staff.
