The DJI Mini 2 SE is DJI’s latest low-cost Mini drone, in a protracted line of Mini drones, launched in March of 2023.
What makes the Mini 2 SE a well-liked drone is its acquainted Mini 2 form many have gotten accustomed to, its sub-250g weight, its numerous full-sized drone options, and importantly its low price ticket.
With this low price ticket comes the omittance of some options, options costlier drones have.
To maintain the value down, the DJI Mini 2 SE doesn’t have impediment avoidance. It does, nonetheless, have downward imaginative and prescient positioning and infrared sensing sensors to assist in a steady hover.
On this article, we’ll talk about impediment avoidance techniques extra in-depth, in addition to why the Mini 2 SE doesn’t have this method in place.

What’s impediment avoidance?
Drone impediment avoidance techniques are a collection of sensors, within the type of cameras, infrared and ultrasonic sensors, in addition to LiDAR (mild detection and ranging) sensors.
Many drone impediment avoidance techniques make use of a mix of those sensors, with costlier enterprise-level drones using all 4.
All of those techniques collect detailed info on their surroundings.
As soon as that info is gathered and analyzed, all in milliseconds, it’s then utilized in detecting potential obstructions and obstacles, thus enabling drones to keep away from them.
Having impediment avoidance is very helpful as drones have superior to the purpose of totally autonomous flight, as is seen within the case of DJI’s Lively Monitor capabilities and Litchi’s waypoint mission-based platform (extra on this later).

Impediment Avoidance Cameras (imaginative and prescient sensors)
As with all digital camera system, the cameras in an impediment avoidance system are used to take visible information of the surroundings (within the type of footage and video) after which are analyzed by the drone’s laptop to acknowledge and monitor objects and obstacles within the rapid space.
Impediment avoidance digital camera techniques are widespread imaginative and prescient techniques on many drones however undergo from numerous exterior influences and circumstances, reminiscent of lack of sunshine and even the velocity at which the drone is shifting.
Due to this, when DJI drones are in Sport mode, the imaginative and prescient sensors are disabled.
Infrared sensors
The place impediment avoidance cameras and imaginative and prescient sensors wrestle to offer correct information in low mild and high-speed environments, infrared sensors can collect information based mostly on, not mild, however as an alternative, the warmth emitted by objects within the surroundings.
The usefulness of those sensors comes into play in very low to no-light conditions and areas the place fog and smoke are a problem.
Infrared sensors are usually discovered on drones which might be deployed in emergency response conditions or when on the lookout for lacking individuals or misplaced pets.
Ultrasonic sensors
The commonest and cheap sensors within the line-up are ultrasonic sensors.
These sensors ship out soundwaves (sonic) into the surroundings after which calculate the time it takes the wave to hit an object and return to the sensor.
These are very efficient in any lighting situation, and fairly correct, however have their limitations in that small objects like tree branches and energy strains are troublesome to detect, if even in any respect.
LiDAR
LiDAR or Mild Detection and Ranging techniques are costly and power-hungry techniques utilized in extra expensive enterprise and commercial-grade drones.
LiDAR techniques use lasers to measure the space between the drone and objects and obstacles within the drone’s flying surroundings.
After this, an in depth 3D map of the drone’s environment is created, with the drone capable of fly by way of stated surroundings simply.
Whereas extremely correct, once more, the sort of system is dear and never usually seen in client drone purposes.
Advantages of impediment avoidance
The most important profit of impediment avoidance is security.
With impediment avoidance on and, in DJI drones APAS (Superior Pilot Assitance System) set accordingly, drones will work out options to both cease previous to hitting an object or work their approach across the impediment within the surroundings, avoiding further objects.
Because it goes with impediment avoidance, we all the time counsel pilots to not totally depend on these techniques, as they aren’t infallible.
There have been loads of recorded checks on-line the place drones have misinterpret the rapid environment and crashed into objects, whether or not shifting objects or stationary.

The second profit of impediment avoidance techniques is having the ability to carry out totally autonomous flight patterns.
DJI is well-known for together with clever flight modes, like Focus Monitor, of their costlier drones which have impediment avoidance.
With Focus Monitor you’ll be able to use Lively Monitor, Highlight, and POI (Level of Curiosity) modes to observe and movie a topic in numerous methods, with out having to regulate the drone in anyway.

Likewise, DJI and third Occasion firms have numerous waypoint flights the place you’ll be able to inform the drone the place to undergo utilizing a collection of flags or markers and the drone will do the mission, once more, with none further stick enter from the operator.
Likewise, we all the time counsel you not totally depend on impediment avoidance in these conditions and keep alert to airborne risks.

The third profit of impediment avoidance is the power to fly drones indoors with fewer worries.
Flying indoors for some could be demanding, as there are much more obstacles indoors than out, a few of these costly, a few of these within the type of overactive pets that may search out a drone and floor it.
With impediment avoidance activated indoors, the drone will be capable to higher keep away from partitions, followers, lamps, ceilings, vases, and no matter else is perhaps in a house. Including props guards up the safety much more.

Does DJI Mini 2 SE have impediment avoidance?
Sadly, the Mini 2 SE doesn’t have impediment avoidance, because it has no imaginative and prescient or ultrasonic sensors for this goal.
For a lot of, it is a slight disappointment, as there’s a Mini DJI drone within the Mini line-up that does certainly have impediment avoidance, the Mini 3 Professional. Albeit at a better price ticket.
Why doesn’t the DJI Mini 2 SE have impediment avoidance?
The Mini 2 SE is interesting as a result of it’s a comparatively low-cost sub-250g DJI drone, the most cost effective new Mini drone from DJI.
The issue isn’t that the Mini is simply too small for impediment avoidance, because the Mini 3 Professional has all the obligatory sensors in place to perform this.
The Mini 2 SE doesn’t have impediment avoidance as a result of all of it boils right down to worth.
The Mini 2 SE is DJI’s latest cost-effective Mini drone, the stripped-down model of the Mini 2. It’s accessible to many, in numerous international locations.
Including impediment avoidance would increase the fee in two important methods:
- {Hardware}
- Onboard Processing

As talked about earlier we talked about 4 of the sensors that go into an impediment avoidance system.
Omitting the LiDAR, and simply any of the opposite sensors: Digicam, Ultrasonic, and Infrared, all of them incur price. Prices that will push the value of the drone into the Mini 3 Professional territory.
Onboard Processing
This one is somewhat bit tougher to ascertain pricing variations.
Due to the best way impediment avoidance works, after information is gathered in regards to the flight surroundings (whether or not visually or sonically), that information must be labored into one thing helpful for the drone to behave on.
That information must be analyzed and processed and that is carried out onboard through the drone’s processor or laptop. The extra processing energy wanted, the upper the price of the pc.
When you have ever seemed into shopping for a PC or Mac you recognize this all too effectively. Increased-spec computer systems price considerably extra.
The Mini 2 SE doesn’t must course of the info from numerous sensors for impediment avoidance, leading to financial savings in price, as a costlier processor will not be wanted.
Are you able to add impediment avoidance on DJI Mini 2 SE?
Whereas there are ingenious folks within the drone world who can construct virtually something, including impediment avoidance to the Mini 2 SE can be extraordinarily troublesome, if even in any respect attainable.
With the time and expense required to even try such a feat, it could be extra time and cost-effective to simply purchase a Mini 3 Professional, if you’re wanting a DJI-branded sub-250g drone with impediment avoidance.
Likewise, DJI doesn’t present snap-on or screw-on impediment avoidance techniques for his or her drones that at present do not need impediment avoidance capabilities in-built.
Likewise, the DJI Fly app doesn’t have impediment avoidance assist in-built for the Mini 2 SE, because it does for the Mini 3 Professional.
If it was even attainable to vogue some form of impediment avoidance system for the Mini 2 SE, DJI Fy wouldn’t be capable to activate it or use it.
What different sensors does DJI Mini 2 SE have?
Should you had been to have a look at the underside of the Mini 2 Se, you’ll see that it does certainly have some form of sensors on the underside. These are the downward imaginative and prescient and infrared sensing techniques.
Each of those techniques, mixed with GPS positioning make sure that the Mini 2 SE can maintain its place when hovering, all inside a 3.9″ accuracy vary, per DJI.
With these techniques all in place, the Mini 2 SE can also be able to extra steady flight whereas indoors.
