Motion Sensor in Battlefield: Bad Company 2
The Motion Sensor is a gadget utilized in the Battlefield series. It is an integral tool for scouting and collecting real-time intelligence, this portable high-tech device is designed for sensing even the slightest twitch of movement, alerting the owner when an enemy has breached the premises on foot or by vehicle.
They can be thrown much like a grenade to help spot enemy infantry and vehicles in its radius. They operate for a short period of time, after which it will no longer detect enemies.

Battlefield: Bad Company 2[]
— In-game description
The Motion sensor can detect enemy activity within a 25 meters radius.
The MTN-55 Motion Sensor is a gadget featured in Battlefield: Bad Company 2. It is only available to the Recon class with only a maximum of three able to be carried. Motion sensors displays enemies within its detection radius of 25 meters on the mini-map as red triangles, and has a shorter active time of twenty seconds.
Only one motion sensor can be used by a player at any given time; if another is used while the first one is still active it will be replaced by the second one. However the sensors now also send out a beeping noise whenever an enemy is detected, alerting the user in addition to their target. They can also be replenished by ammo boxes from Assault players, and resupplied very quickly.
Motion sensors, as their name implies, can only detect motion. If a player remains still, the motion sensor will be unable to track the player. Paradoxically, motion sensors will detect enemy explosives that are planted (i.e. mines) by placing an icon on the tacmap, but this icon will disappear once the motion sensor has expired.
Enemies killed within the range of a motion sensor give the player a 'motion mine assist' worth 20 points, with 10 extra points if the kill was by a squadmate.

Battlefield 4[]
— Battlelog description
The Motion Sensor is a gadget featured in Battlefield 4. It functions in a similar manner to the Bad Company 2 counterpart.
Every few seconds, the Motion Sensor emits a pulse that reaches in a 25-meter radius (35 meters if Level 3 of the Spec Ops Field Upgrade is active), creating an audible beep and temporarily displaying the location of any enemy in range on the minimap for the length of the pulse but can alert the enemy of the deployer's presence. The range of the pulse is not blocked or impeded by any objects including doorways, walls, or other props.
It should be noted that Motion Sensor, similar to the T-UGS, can detect enemies vertically as well as horizontally, even if it is blocked by a roof or floor. Motion Sensors last only temporarily, whereas unlike the T-UGS, are permanent until damaged and destroyed by either enemy or friendly forces. The Motion Sensor cannot detect enemies that are standing still, or are moving in a crouched or prone position. Unlike the T-UGS, the player can deploy the Motion Sensor without having to break from cover and expose themselves to enemy fire. The Motion Sensor can be thrown like a grenade to difficult to reach places or surfaces where T-UGS cannot be deployed easily or quickly without being exposed or discovered by enemy forces.
Patch notes[]
- As of December 2015 Battlefield 4: Legacy Operations, the MTN-55 Motion Sensor will now "explode" upon expiration to make the event more visible. The explosion has the same effect as with equipment destruction, and deals no damage to any players. Despite this, a damage indicator is still shown on screen, with blood stains and the player grunting in pain.

BATTLEFIELD: 2042[]
— In-game Description
The Prox Sensor is a throwable gadget featured in Battlefield 2042. Unlocked at level 22, it functions in a similar manner to past installments and reveals enemy locations within a small radius. Active sensors have a team-colored flash, with the user's own grenade having an audible pulse.
Similar to Frag Grenade, enemy Prox Sensors can be thrown back by pressing Interact, and then reveal enemy's position in reverse. However, doing so is obviously dangerous because player's character is now clearly in the sensor's scanning and probably open area. For safer handling methods, players can destroy enemy sensors by directly shooting them, just like do with other small gadgets.
Different with T-UGS that similar in functions, Prox Sensors last only temporarily, and both numbers that can be carried and deployed are 2. Its scan radius is 15 meters, less than T-UGS.
Battlefield: Bad Company 2[]
— In-game Description
For BC2 Protal, Motion Sensor is a "default" or "innate" gadget for Recon class that unable to be removed, like the Repair Tools for Engineers. By default it will be the 3rd item in player's inventory, while the 4th can be Mortar Strike or C4.
Motion sensors, as their name implies, can only detect motion. If a player remains still, the motion sensor will be unable to track the player. Only one motion sensor can be used by a player at any given time; if another is used while the first one is still active it will be replaced by the second one. However the sensors now also send out a beeping noise whenever an enemy is detected, alerting the user in addition to their target. They can also be replenished by ammo boxes from Assault players, and resupplied very quickly.
Strangely enough, only when the Motion Sensor lands will the character have a voiceline like "Motion Sensor out".

Trivia[]
General[]
- The motion sensor's design resembles that of Battlefield 2142's Motion Mine, though it lacks the arming switch. Its appearance in Battlefield 4 may be the precursor to the final II-29 Motion Mine seen in 2142.
- When a motion sensor is thrown, it makes a sound when it hits the ground. Hearing the telltale 'clink' and subsequent beeping will tell players that they have been spotted and should take some sort of action.
- Standing still will not alert the player of their presence (looking around, aiming, using weapons and crouching are not detectable either). This may throw the enemy off, thinking that the player has left the area or been killed.
- Any enemies picked up by the motion sensor only appear on the map. Pips will not appear above an enemy's head. This makes the sensor less useful in Hardcore gamemodes as the distinctive bleep is the only giveaway of nearby enemies.
Battlefield 4[]
- For the 2015 Holiday update on the Community Test Environment, a completely white textured version of the Motion Sensor was added to the game as a gadget called the Snowball. Players had an infinite supply of Snowballs, and could kill enemy players with two hits with them. The Snowball created a small explosion on impact, however, and was able to kill the player throwing them if they were aiming at the ground.
