We often drive on a bridge fitted with some solar powered equipment, and recently they added a solar powered camera pointing towards the river, so I became curious and decided it would be fun to have a look, and find out what it was all about. There are now 3 solar powered and connected systems.
The first system has a larger solar panel connected to a Bosch camera, and a white box…
The sticker on the box gives away the purpose of the system: “National Disaster Warning Center”
If we look the other side of the system we’ll see an antenna (for 3G/LTE?) as well as a light pointing down to a scale to measure the water level… Probably not the most cost effective way of checking out the level, but it works, and they should have a live feed in case something goes very wrong, and it might be able to measure other characteristics like water velocity.
The system in the middle of the bridge has a different antenna, like a TV antenna, and a cylinder that could be to measure the level of rainfall, and possibly contain temperature and humidity sensors too, as it looks a little similar to another older system.
The control box also has a few stickers, explaining the device is used to check water and rain fall level automatically, that such systems are installed in 31 locations and 122 stations, and managed by the “Telemetry station department”. It has apparently been installed or manufactured by a company called Multiproof Co., Ltd specializing in “systems for the Environment instruments and GPS Fleet Management System”.
