Tips for pressure sensors in road

I’ve tried finding answers to this online, but with no luck.
My rides find myself going through gates that open for cars when they slowly approach he gate and sensors in the road are aware of the car.
These sensors are essentially the outline of a large rectangle, almost the same width as the gate.
Any tips on how to trick them? I realize weight may be the only factor to trip the sensor, but I’ve found myself trying to ride over them in circles and zigzagging, but to no luck. I’m sure I look extra goofy to those witnessing this

Ride over them wearing a 35kg backpack....0

Never come across them in the UK. I have had sets of traffic lights that were triggered the same though. Only the cars would set them off. So it was either just wait for cars to come or find a different route. .
Who owns the gates ?0 -
They are called scoop sensors. You need the size and mass of a vehicle to trick them.0

It’s a series of neighborhoods that I live near. Super nice roads and less traffic in them
Scoop sensors...I’ll look them up. Thanks!0 -
Are there different types of sensors? End of our street had on demand lights and they never used to trigger with our bikes unless we had a trailer attached for some reason. Now they're working but only if my wheels are on the tar sealed gaps. It can't be weight but I wondered if there's an electrical sensor there.
Not really bothered because I either wait for the lights to change or I nip out on red because I commute before traffic builds up so nobody around to catch me. Of course I walk my bike around the corner.0 -
It's an induction loop and is triggered by a metal object of sufficient size running over it. Carbon framed bikes do not contain enough metal nor do some lightweight metal ones. My Ti bike for instance does not trigger them but my steel tourer does.0

As above they are induction loops and need a ferrous metal (Steel or iron content ) to trigger them. Metal cleats might work if you stood on the line
Sometimes. Maybe. Possibly.

One trick suggested in the motorcycle fraternity is to mount a small neodymium magnet on the underside of the frame, which should interact with the induction loops and trigger the sensor.Cube Reaction GTC Pro 29 for the lumpy stuff

I used one in my pedal axle hex to measure cadence. They don't fall off.darkhairedlord wrote:

That should work. Maybe....The above may be fact, or fiction, I may be serious, I may be jesting.

A small cadence sensor magnet is more likely to cure arthritis than it is to trigger an induction loop under tarmac. You might as well sit around waiting for a random fluctuation in the earth's magnetic field, or a car.PBlakeney wrote:

I should know better where your posts are concerned, but I just looked this up. As far as I can tell, there is no such thing as a 'scoop sensor'. Can you provide some further info, or a link to where this term of reference is used? I will happily be corrected...0 -

Ah thanks. I missed the bit in the OP's post about the gates being in the middle of the ocean... 0 -

When you stop on it, try laying your bike over which presents the spokes as a metal object for the sensors to pick up. Gives much more surface area to interact with... If the frame is metal that will help too.Open One+ BMC TE29 Seven 622SL On One Scandal Cervelo RS0 -
It wasn't me who suggested using a small neodymium magnet. I have no idea if it will work.First Aspect wrote:

I simply suggested a way of attaching it so it does not fall off.The above may be fact, or fiction, I may be serious, I may be jesting.

If you crosschain big big the chain will be closer to the tarmac and set off the sensor.0

If you crosschain with 35kgs on your back then the tyres will deflect more and you'll be nearer to the floor still (assuming you didn't get another puncture and had to abandon your ride before you arrived at the sensor).0 -
Yeah, this. Vehicle gates at work would open if you laid the bike flat over the induction grid.Wheelspinner wrote:

And yeah, less likely to work with a carbon bike, more likely to work with a steel one...0 -

Just a small point, but some of us are already 35kgs heavier than others.Shortfall wrote:darkhairedlord wrote:If you crosschain big big the chain will be closer to the tarmac and set off the sensor.
