Workbench Level 2, 25s, yields 1
Faster at a higher workbench: 12.5s at Workbench Level 3.
Researching the blueprint costs 30 scrap at a Research Table.
Crates, barrels and NPCs that drop the HBHF Sensor, most likely first
| From | Chance | Amount |
|---|---|---|
 Locked Crate | 1.3% | 1 to 2 |
 Elite Crate | 0.78% | 1 to 3 |
| Scientist PT Boat Dry Box | 0.73% | 1 to 3 |
 Military Crate | 0.42% | 1 |
 Underwater Lab Military Crate | 0.42% | 1 |
 Wagon Military Crate | 0.42% | 1 |
Missile Silo Scientist (underground) | 0.3% | 1 |
 Normal Crate | 0.22% | 1 |
 Wagon Normal Crate | 0.22% | 1 |
Scientist | 0.074% | 1 |
Heavy Scientist | 0.061% | 1 |
 Treasure Box, mission reward | 1.6% | 1 to 2 |
 Gingerbread Mine Present, Christmas event only | 0.42% | 1 |
Chance is for one container opened or one NPC killed. Amount is how many it holds when it holds any.
Each swing charges the share of the cost for 50 health, rounded up to whole resources, and restores as much health as it paid for, which can be more than 50. Nothing can be repaired for 30 seconds after it takes damage.
What the HBHF Sensor gives back in each recycler
| Recycler | Efficiency | You get |
|---|---|---|
| Red recycler | 75% | 56 + 25% Metal Fragments |
| Green recycler (powered) | 60% | 45 Metal Fragments |
| Green recycler | 50% | 37 + 50% Metal Fragments |
| Yellow recycler | 40% | 30 Metal Fragments |
The HBHF Sensor breaks down into Metal Fragments.
A recycler takes them one at a time, so a full stack of 5 goes through in 5 cycles.
Figures are for one item in perfect condition. Each recycler’s name opens its full table at this item. “56 + 25%” means 56 every time and a 25% chance of one more.
In Rust, HBHF Sensor is a electrical in the Electrical category (item ID #-1507239837, console shortname electric.hbhfsensor). In active play, it follows standard server rules for electrical gear across procedural maps. Inventory storage stacks up to 5 units per slot, and uncollected ground drops despawn after 20 minutes.
A Heartbeat, Breathing, Humidity and Footstep sensor. Passthrough is equal to the number of humans detected in a 10m radius.
Crafting HBHF Sensor in Rust takes 25 seconds at a Workbench Level 2 once the 30 scrap blueprint node is unlocked, with all ballistics, crafting, and durability values read from the Rust game files. Shredding a spare copy at a green recycler recovers base materials at fifty percent yield (vs forty percent at safe-zone yellow units). Placed structures heal with a Hammer using raw materials from your inventory.
When choosing between HBHF Sensor and related electrical in Rust, prioritize researching a looted or traded copy at a Research Table (30 scrap) whenever you want to skip the 210-scrap tech tree path and save 180 scrap, or unlock the tech tree branch when your group also needs the prerequisite blueprints.
| Item | Category | Stack Limit | Craft / Source | Tech Tree / Research | Green Recycler Yield |
|---|---|---|---|---|---|
| HBHF Sensor | Electrical | 5 per slot | Workbench Level 2 | 30 node / 210 path | Not recyclable |
| Seismic Sensor | Electrical | 10 per slot | Workbench Level 2 | 30 node / 225 path | Not recyclable |
| Medium Neon Sign | Electrical | 5 per slot | Workbench Level 1 | No blueprint | Not recyclable |
| CCTV Camera | Resources | 64 per slot | World loot / gather | No blueprint | Not recyclable |

To compare HBHF Sensor against every item in its inventory category, browse All 83 items in Electrical, or plan prerequisite scrap paths on the The Engineering Workbench tech tree, tile by tile.
The HBHF Sensor has 200 health once placed in Rust. It belongs to the Electrical category under numeric ID -1507239837 across 83 electrical, while F1 console command inventory.giveid -1507239837 5 spawns 5 units for testing across 83 published Electrical entries (79 with crafting blueprints).
The HBHF Sensor is crafted at a Workbench Level 2 from 75 Metal Fragments, once the blueprint is learned in Rust. Raw ores smelt into metal inputs in a furnace while non-craftable components must be looted from monument crates before queuing the craft at your workbench.
The HBHF Sensor drops from 11 container and NPC loot tables in Rust, led by Locked Crate (1.3% chance), Elite Crate (0.78% chance), and Scientist PT Boat Dry Box (0.73% chance). Each listed probability reflects a single container opened or NPC killed, and found copies can be repaired or researched at base.
The HBHF Sensor recycles in Rust at an unpowered green recycler into 37 Metal Fragments plus a 50% chance of one more. Full material recovery applies to an undamaged copy, whereas worn items return proportionally fewer resources based on their remaining condition bar when shredded.
The HBHF Sensor takes 25 seconds to craft, down to 12.5 seconds at Workbench Level 3 in Rust. It sits in the Electrical catalog with item ID -1507239837 alongside 82 related electrical, with F1 console command inventory.giveid -1507239837 5 across 83 published Electrical entries.
The HBHF Sensor repairs in Rust once placed with a Hammer for up to 38 Metal Fragments at full wear (4 swings). Hammer repairs draw materials straight from your inventory with zero maximum-health penalty, provided the placed object has not taken damage within the last 30 seconds.
Blueprint progression for HBHF Sensor at Engineering Workbench in Rust charges 30 scrap on the target node and 210 cumulative scrap along the prerequisite branch, while direct blueprint study at a Research Table charges 30 scrap. It belongs to the Electrical category under numeric ID -1507239837 across 83 electrical.
Dropped on the ground in Rust, the HBHF Sensor despawns after 20 minutes by default. Picking it back up into a player inventory or storing it inside a base container immediately resets that ground despawn timer, which the server scales by item rarity tier.
The HBHF Sensor has 32-bit signed item ID -1507239837 and shortname electric.hbhfsensor in Rust. Server plugins, custom loot tables, Vending Machine listings, and automated Industrial Conveyor filter strings reference these two identifiers under the Electrical category (stack limit 5 units per slot).
Server administrators in Rust spawn the HBHF Sensor in the F1 developer console with inventory.give electric.hbhfsensor 5 or inventory.giveid -1507239837 5 for 5 units. Both console spawn commands require administrator or moderator privileges on the server, while regular players can bind a quick-craft shortcut key instead.
