<put instro hat on >

technically it is not pressure sensitive.

from your descriptions I would have to guess it looks at the current/load which would increase when encountering an object in its path.

there are many types of sensors you could use for added complexity to detect objects , or even go a more complex route - RFID the cat for instance - 3d lidar - IP cameras with animal people AI detection.

as people make their homes smarter , more automation will be common .

as to the having to lay a power cable out to the gate , I am sure now there are systems with solar panel and battery that would do the job - and wifi that could connect to your home network which could and could be configured to easily allow you to open the gate from the other side of the world.

"For every action there is an equal and opposite reaction. " everything else is semantics

Piezoelectric actually means pressure-electric , Piezon meaning precure in Greek.
Ours works electronically , and though I had not cared to find out, I am sure it must be by some integrated piezoelectric circuit.
Below is a short video (less than a miute) I made for demonstration purposes. I used a paint bucket for a subject.
PS: I made this gate myself

electric gate - YouTube

Electric was not an issue for us as we had the electrician bring power to the gates for lights, so electric was already there (something to consider when building).
But I can see how this can be a problem for homes with long driveways.
They do have solar powered gate openers for just such applications, Those devices contain a rechargeable battery for when the sun is off.
But yes you are right ,
More automation will certainly be common. I have "smart" switches and outlets installed all through the house , that are operated via the internet. Also have an automatic fish feeder for my koi pond, And internet connected video cameras, all accessible from any place in the world. The gate can also be operated with my Iphone. (though I have never done it , but I do have the app. Just like there was a time when no one had cell phones, but now we cant live without it, there will be a time soon that we will be wondering how we lived without home automation.

Piezo crystals generate a potential difference and / or a current in a circuit when they are under pressure

I am sure your gate motor does not have a piezo device determining if your cat is being squashed

was being aquached, was. which is why I got this one.
Did you watch the video? only a few seconds short.

A masterpiece. Much like Hemingway's "baby shoes" story, short but perfectly formed. Cannes beckons.

What I saw though was a bucket getting squashed, I didn't see the gate back off at all. Is it supposed to auto-reverse or does it just squash up to a certain pressure then stop and hold its victim?
I know many people have motorised gates and are happy with them. For me, I remain unconvinced that my doglet at 3.5kg would represent sufficient resistance to initiate an auto-release until it was two half doglets.

It absolutely did not get squashed, it got squired, and the gate stopped. To get it moving again you have to press the remote control. and it will move in the reverse direction,
I took the bucket placed it in a scale and pressed to get the same deflection. It registered 15 lb

An open and shut case!

Teak Doors the ultimate solution, admits the cream, protects the dogs and pussies, rejects the rest!

It seems to be about a bunch of guys worried that on the oddest of chances, their pet my get squashed by their electric gate.

Next up will be don't drive because you might hurt an animal.

Nahh, I would not mind if one or two, or even three of the dogs got "squashed". I would of course faint devastation to the wife, and even shed a crocodilian tear , but deep inside there will be a smile and perhaps even a happy tune.

But I was concerned that one of my friends might pass out drunk in my driveway (as it often does) and get quashed by the gate before I have a chance to collect the money the prick owns me.

I would of course search their pockets before I report the unfortunate incident, but knowing the lazy bums I am sure they will be empty.

Classic!

**JuniperFred21** · 31-03-2023, 08:57 PM

Manual - in my opinion - is always the way to go - anything under power is more of a pain than it is worth. I bought of Ali Express last year and very happy with price and product.

**P76** · 11-07-2023, 09:34 AM

CDNicKS,
Did u get your gate motor installed?
Any updates?

**Ghost61** · 11-07-2023, 10:13 AM

Experience of Centurion D10 for last 10yrs+ in Thailand is mostly good. Changed motor batteries 2-3 times (from Homepro); Keyfob batteries changed no problems. Manufacturer's website is good for trouble shooting (detailed pdf manual can be downloaded) and in first direct correspondence with customer service, they were quick to reply. Recently, after about 3 months without use, error message Motor Disconnected was displayed so gate inoperative in auto mode. A quick gander on YT and decided to inspect the electric motor brushes. Both seemed good, hardly worn. Cleaned and refitted. Error code disappeared, motor operational and gate AOK.
So far, all above problems easily rectified by moi.

Bought the cheapest Thai made kit online and installed it 3 years ago, it uses magnets to control limits and has torque adjustment. It works fine, however, I am an industrial installation engineer, so I have half an idea how to do things properly, it is not hard but a few different skills are required and attention must be paid to proper alignment to avoid stress points. The remote uses 12v cells and one of the remotes has never worked even after a little tinkering and inspection for for solder bridges or breaks. Once installed the motors are easy to swap out if they crash and burn...go for it.

**P76** · 28-08-2023, 04:56 AM

Thanks for the replies Ghost61 and Globin.
Will be installing or having one installed December or January.

Ours is an Italian brand called NICE. 25.0K THB from the dealer in BKK. We went for this as it's a heavy 5.0m gate.
Some good features: 1 metre opening for motor bikes and scooters, crawl speed closing for the last 30 cms, variable open time setting from 15 to 30 seconds.

Hi, would you have the name of the company that supplied and installed the gate and motor please?

We're looking for suppliers in Rayong/Patttaya/Bangkok area, we had one quote so far and looking to get more quotes and preferably a recommendation from people here:

Galvanized steel gate work
Powdercoat black paint, fence work site 5.5 meters, price 2000/1 meter 5.5*2000 = 11,000 (half fence price)
Gate - work site 1.8*4.5m =8.1 sq m *3500 =28,000
price of remote control motor, Powertech dc 600 kg, has a backup battery, supports wifi = 18500
I believe it's this one but waiting for confirmation - Powertech PLH 600 wifi - Powertechthailand : Inspired by LnwShop.com

Total approx - 57,500

Is this about right?
Thank you

what was my problem ?

when the gate is closing, the magnet at the gate sliding door is giving a magnetic puls to a little black box at the gate motor,
it should ... stop the motor.

But in the video, you can hear, how the gatedoor is crashing.

Every time, when you can hear this crashing noise,
the gate may be closed, but the motor did not stop working.

So in case, you leave your home and close the gate, when the motor is still working, after the gate is closed,
it caused for a long time, till the electric cable is getting so hot, that the isolation is fading away, and you got a short cut-

In the end, I had 2 electric cabels in 2 pipes, one positive, one negative, that no shortcut can happend between the house and the gate.

Now, I have the 5 or the 6 magnetic black box at the gatemotor,
but it still happend, after 15 or 20 closing attempts, the stop signal is getting lost,
and the gatedoor closed with a chrash noise, so that the motor is still working.

( it sucks, every time, when this happend, switch out the breaker, switch the motor to manual mode, realize, that the gatedoor is still not moving, deinstall the metal rails from the gatedoor, to open the gate manual again)
could the electric impuls from the black magnetic box, send to the controllerboard at the wall, and back to the motor, have sometimes less than the minimum voltage ? - ... I don t know.
