I dropped into a Dam raid with a busted rifle and a single objective: finish the Weather Monitor stage before extraction. grenades sang; a Scrappy scavenged the same crate I had marked. I got the parts and learned the quick math that separates shallow runs from meaningful gains.
I’ve tracked Projects through dozens of raids on PC and consoles, and I’ll tell you what I do when time is limited and inventory is tight. You’ll get a clear plan for each stage, where to farm the items, and the small habits that turn noise into steady rewards.
When the map opens I notice players surge toward Industrial zones — All ARC Raiders Weather Monitor System project requirements and how to complete
The Weather Monitor System is a five-stage Project in ARC Raiders. Stage 1 is immediately available if you have Projects enabled; the later stages are gated by items you must supply. I’ll walk you through each stage, show how to get the parts fast, and point out the reward gaps so you can decide what to chase first.
How do I complete the Weather Monitor System project?
You complete the Project by submitting the required items for each stage. I break the runs into short, repeatable routines: target a zone, clear high-yield spawns, loot quickly, and extract. The parts list is a thrift-store map — small finds add up into a full submission.
Stage 1: Atmospheric Pressure
| Requirements | How to Get | Rewards |
|---|---|---|
| 25 Plastic Parts | Found as random loot from any map. Also collected by Scrappy. | 5 Durable Cloth |
| 15 Metal Parts | You can find it from Scrappy or from random loot. | 5 Great Mullein |
| 5 ARC Alloys | Destroy and loot ARCs. | 5 Antiseptic |
| 3 Oil | Found as normal loot. You can find them more frequently in Industrial zones. | 3 Vita Shot |
Quick tactic: prioritize Industrial zones first for Plastic and Oil, then hit Scrappy spawns on your exit. If you see ARCs, finish them for ARC Alloys — they’re the slowest drop in Stage 1.
Where should I farm electronic parts and sensors?
Electrical and Residential areas are your best bets for Wires, Sensors, and Camera parts. Steal the time-limited wins by rushing rooms that spawn Snitches, Comets, and Fireflies — they drop unique components that these stages demand.
Stage 2: Sunlight
| Requirements | How to Get | Rewards |
|---|---|---|
| 1 Snitch Scanner | Obtain by destroying Snitches | 10 Processor |
| 3 Wires | Get as loot. Can be found more frequently in Electrical zones | 5 Advanced Electrical Components |
| 3 Sensors | Can be found in different types of ARCs. | 3 Zipline |
| 1 Comet Igniter | Kill and loot a Comet | 1 Raider Hatch Key |
Snitches and Comets are priority targets here. If you can clear one patrol that houses a Snitch, you’ll shave dozens of minutes off multiple runs.
Stage 3: Precipitation
| Requirements | How to Get | Rewards |
|---|---|---|
| 5 ARC Powercell | Can be obtained from ARCs like the Rocketeer, Bastion, and Bombardier. | 3 Medium Gun Parts |
| 5 Canister | Obtain as random loot. | 2 Complex Gun Parts |
| 5 Steel Spring | Obtain as random loot. Found more often in Industrial zones. | 3 Advanced Mechanical Components |
| 1 Fine Wristwatch | Can be obtained as loot, preferably from Residential areas. | 1 Renegade Level 3 |
ARC Powercells usually come from specific ARC types; if you see a Rocketeer, Bastion, or Bombardier, clear them before you chase random loot. The Fine Wristwatch tends to spawn in Residential; if a map lists that area spawn, loop it quickly.
Stage 4: Humidity
| Requirements | How to Get | Rewards |
|---|---|---|
| 10 Duct Tape | Obtain as random loot. | 10 Explosive Compound |
| 3 Rusted Bolts | Obtain as random loot, preferably from Industrial zones. | 3 Showstopper |
| 1 Water Pump | Obtain as random loot. The Hydrophonic Dome Complex in Dam Battlegrounds spaws them pretty regularly. | 3 Trailblazer |
| 3 Wasp Driver | Can be obtained from destroyed Wasps | 1 Extended Barrel |
Hydrophonic Dome Complexes are worth a detour if you need Water Pumps. If you’re short on Duct Tape, clear low-threat buildings — half of my successful runs include a quick residential sweep for tape and wristwatches.
Stage 5: Temperature
| Requirements | How to Get | Rewards |
|---|---|---|
| 3 Camera Lens | Can be obtained as random loot. | Yet to be determined |
| 1 Damaged Heat Sink | Obtained from random ARC debris that you can find commonly on your raids. | Yet to be determined |
| 1 Firefly Burner | Obtain after destroying a Firefly. | Yet to be determined |
| 3 Voltage Converter | Can be obtained as random loot. | Yet to be determined |
Stage 5 still has unknown final rewards at the time of writing, so weigh your time. If you’re chasing gear or tokens, prioritize the stages with known payouts first.
There’s no expiry on the Weather Monitor System Project, so you can pace these runs. Finish all five stages and you’ll receive an Anemometer Backpack Charm and 250 Raider Tokens. Think of the charm as a small badge and the tokens as trade fuel for upgrades and shuffles.
Platform note: players on Steam, PlayStation, and Xbox report similar spawn behavior, so these tips apply across PC and console. I use short, targeted loops for repeatability — you should too.
The work pays off if you collect parts habitually: small wins compound into completed stages and steady progression. This project is a slow-burning clockwork.

So what will you prioritize on your next raid — speed, targeted spawns, or methodical looting to finish all five stages first?
