These little gadgets have started appearing around the Universal United Kingdom Resort site.
They're environmental monitoring stations that continuously measure things like dust, noise and ground vibration during construction. If any of those levels go above set limits, the system can automatically alert the site team so they can investigate and take action.
It's good to see Universal taking its environmental responsibilities seriously and keeping a close eye on the impact of the construction work.
These photos were taken on two different days, but they're in the same location. You can see this one driving past on Woburn Road.
