Nutrients, such as phosphate nitrate and nitrite are central in many environmental processes within the marine and fresh water environments, including several microbial, plant and animal metabolic processes1. However, these processes are currently under threat from elevated levels of pollutants, the impacts of climate change and the loss of biodiversity and habitat 2. Cost-effectiveness of sensing technologies are required to monitor their condition, here we present a cost-effective sensor for the autonomous detection of nutrients in natural waters. The sensor is based on a combination of microfluidic analytical systems, colorimetric reagent chemistry, low-cost LED-based optical detection and wireless communication. The sensor been tested through a number of deployments in areas of environmental interest, such as Ny-Aselund Svalbard on the Italian Artic Base, Sardinia Italy, CNR Italy testing Lagoon and the Mediterranean onboard the RV Minerva Uno.<br/><br/>
