New firmware has been released and already loaded to eBay devices. Main features: * improved compatibility for parking barriers with card readers * better activation ability for very weak signal * user selectable LED blinking pattern V2 devices - 2.07 www.ebay.com/itm/332153452418V3 devices - 3.07 www.ebay.com/itm/332346508692Both devices has exactly the same firmware and performance. The difference only in electronics improvements.

How the ACTIVE Green Light Trigger works (blinking LED confirms sensor detection):

Whats the working principle behind Green Light Trigger? Inductive-loop sensor (wire loop in asphalt) is a metal detector. It creates electro-magnetic field with frequency 10kHz - 200kHz. Large conductive object like car's underbody, decreases loop inductivity and increases free running frequency. This small frequency change (less than percent) is being registered. Scooters and motorcycles create very small changes, often below sensitivity threshold. My ACTIVE Green Light Trigger responses to the road sensor to increase running frequency. GLT device receives sensor signal, precisely measures it and transmits specially generated signal back to the sensor. It may sounds simple, but there are a lot of digital signal processing and complicated mathematical calculations behind. The device works fine around the world and got few reviews on facebook

the Federal Highway Administration suggests is that we ride/stop over the left or right edge of the sensor My device (Active Green Light Trigger) works when motorcycle / scooter is within the sensor loop, and even outside but next to the loop. In other words, it does not matter where to stop related to the sensor loop(s).

First customer review on my facebook, in visitor posts. Hope it will be interesting.

Hope this duct tape will survive the rainy winter.
In my country, there are no single loop sensors. All traffic light sensors are multiple loop sensors here. The sensor controller reads all loops periodically (time division), and they can also detect traffic direction. The only exception is a single loop in advance of 10 - 30 meters to intersection. It should increase green phase in case of traffic.
My device will not activate this single loop sensor when passing with high speed. Currently, I use 100 ms measurement time frame after first signal detection, so if riding with 50 km/h = 13.9 m/s, the vehicle will advance for 1.4 meters in 0.1 second, thus, it will activate loops which longer then 1.4 meters (at 50 km/h speed). I can reduce detection time to 15 ms, converting to sensor frame length 21 cm at 50 km/h speed.
It is only theoretical thought regarding single short sensor loop passed at speed. And it hard to test in real life.
In all other cases the device works fine.

On the videos was installation for motorcycle. Here is the example of the simple installation to a scooter:

I'm considering one,I saw your videos, and from an electronics standpoint it makes sense how it works You are welcome.
