A sensor system is developed for long term monitoring of environmental parameters such as pH, conductivity and temperature in sewage systems. The ultra-low power design of the sensing electronics enables the system to perform long-term measurements without the need of external power supplies or the change of batteries. The modular housing concept as well as the sensing elements withstand the harsh conditions and have as little influence on the environment as possible. The integration of the sensor probes into the housing design was a trade-off between a sufficient protection of the sensitive sensing areas against contamination and damage and a good contact to the observed medium for a fast response time of the sensors.
