Westermo GSM modems used in 6 remote self powered telemetry systems to monitor an ecologically sensitive marsh area.
The Marsh, located in PARQUE NACIONAL DOÑANA is one of Spain's most ecologically important sites and a major tourist destination. The park falls under the responsibility of the Ministry of Environment & National Parks.
The Ministry required a method to monitor various different environmental variables in the marsh to build a history of its evolution. But with the least possible environmental impact. ACT SISTEMAS, an engineering company specialising in water & environmental projects designed the telemetry system.
The customer requirements
The Ministry wanted to collect information on how various different environmental variables in the marsh change,

In order to build a history of the marsh evolution, while minimizing the environmental impact. The area is inaccessible due to natural obstacles, so the stations must be self-sufficient in terms of power supply and maintenance.
The solution
6 remote stations, each equipped with an OMRON PLC and GD-01 GSM modem. Solar energy is used to power the system. The stations pick up values such as water temperature, conductivity, level, turbidity as well as wind speed, direction, rain level and vaporization. There is a central control system which collects all this data by polling each station via the GD-01, the heart of this central system is an OMRON CJ1M used for data storage.
