Bitstop’s Dissolved Oxygen Sensor is it
FISH KILLS TERMINATOR
WITH improved technology, soon costly fish kills in Pangasinan will be a thing of the past.
The provincial government expressed this optimism when it acknowledged the significance of Bitstop’s Dissolved Oxygen Team entry in the recently concluded Pangasinan ICT 2013 competition as the winner in the Social Innovation category, specifically for its Arduino Dissolved Oxygen Sensor.
The award-winning sensor measures the dissolved oxygen and temperature in the water and is programmed to trigger a water aerator to fire up when the level of dissolved oxygen falls below a set trigger level.

Dissolved oxygen is a crucial factor that marine life needs for survival. Any drop in dissolved oxygen results in massive fish kills. Sudden climate changes, agricultural water runoffs, pollution and other factors contribute to drastic drops in dissolved oxygen.
The device automatically turns off the aerator machine once the optimum desired level is achieved.
The developed sensor offers aquaculture operators not only a cost effective means of monitoring the dissolved oxygen in real time but can work in remote and harsh environments. (low power, weatherproof).
The sensor can be used to help government gather more data to prevent fish kills in rivers and waterways including the effect of oxygenator plants in local waterways.
The winning team, composed of Wilson Chua, project manager; Kristher Vidal, web and DB developer; and Albert Estillore, Arduino programmer, was supported by students of Cagayan State University, particularly Bryan Tapaoan.
The team’s technical adviser was Dr. Westly Rosario, chief of the BFAR’s National Integrated Fisheries and Technology Development Center (NIFTDC).
“With no fish kills, fish farmers can maintain their normal profits while selling at lower prices, benefitting consumers in the end,” Chua said.
