The Fire Bomb with Short-Range Sensor is a Fire Bomb fitted with a motion sensor. It is placed on the ground, armed, and bursts into flames when something moves within about 3 tiles. The fire spreads across a radius of about 6 tiles, just like the thrown version.
The sensor turns the bomb into a trap. It waits at a doorway, a fence gap or a road until a zombie walks into range. The short range makes it the most precise of the three sensor versions. It is the cheapest sensor upgrade, made with the Add Short-Range Motion Sensor to Bomb recipe at Electrical 2. The Engineer is the best occupation for explosives. It can make traps and explosives from the start.
Combat
Stand where the trap should go and choose Arm and set Fire Bomb with Short-Range Sensor from the item's menu. Place Item only sets the bomb down without arming it. Once placed, the bomb beeps slowly four times, then beeps rapidly and falls silent. The silence means the bomb is armed.
From then on, any movement within about 3 tiles sets it off with no warning. That includes the survivor who armed it. The blast starts several fires in a radius of about 6 tiles, and the fires burn for roughly 10 in-game minutes.
The short sensor suits a narrow spot where zombies pass close to the bomb, such as a doorway or a gap in a fence. The medium and long versions trigger from 4 and 5 tiles away. They catch zombies sooner, but they are easier to set off by accident. The timer version goes off after a set delay, and the remote version on command.
Uses
The Add Short-Range Motion Sensor to Bomb recipe takes a Fire Bomb, a Motion Sensor, two Scrap Electronics and a Duct Tape. It needs Electrical 2. The same recipe fits a short-range sensor to an Aerosol Bomb, a Noise Maker, a Pipe Bomb or a Smoke Bomb.

Notes
- Arm and set is the only way to arm it; Place Item leaves it inactive.
- The armed bomb makes no sound before it goes off.
- Back away at once after arming, since the survivor's own movement can trigger it.
- Researching it can teach the short-range sensor recipe.
