33 Buckets Sensor Development

Meeting time


Project description

In collaboration with non-profit, 33 Buckets, this team is developing an autonomous residual chlorine sensor that utilizes electrochemistry to monitor chlorine levels in water. The sensor will be used as part of a chlorination system to support the disinfection of water in Peru. Water is essential to life and many communities in South America do not have access to a reliable source of clean water. The most common method of killing e.coli and other bacteria is through chlorine disinfection. The challenge is measuring the residual chlorine amount in the water; because too much or too little can get the community and children sick. The placement of the sensor or sensors in the community is another challenge to ensure the water is drinkable throughout the community. The solution is to make electrochemical, chlorine sensor that is more cost effective than any other product currently on the market. We have made one sensor in past semesters was a proof of concept. The sensor will continue to be tested this semester to see if any other variables may have any effect on the readings. We are in the process of finalizing the part list to make a second prototype. The team has also started researching maps of the communities in order to determine the placement of the sensors.
