Performance Assessment of Low-cost Water Level Sensor for Water Sensitive Urban Design (WSUD) monitoring in the Tropics

Résumé

Water Sensitive Urban Design (WSUD) has emerged as one of the most important sustainable strategies in integrated urban water management (IUWM). Though increasing WSUD systems have been implemented worldwide, there is relatively little attention paid to monitoring WSUD systems' medium to long-term performance. The relatively limited monitoring efforts restrict the ability of public agencies and private developers to provide adequate maintenance for existing systems and to optimize the design of new systems in urban planning. The attempts to promote monitoring are mainly limited by constrained budgets, especially in developing areas. With the huge economic advantages and flexibility for operation and communication, low-cost sensors (LCS) show great potential in establishing affordable monitoring systems. In this study, the performance of a water level LCS (KIT0139) was tested and compared to the counterpart traditional sensor (OTT PLS) in a laboratory under different controlled conditions. Results reveal that the LCS (KIT0139) has good robustness as there was no significant difference between the 6 individual LCS devices under the testing conditions. Also, the LCS provides sufficient accuracy and precision compared to the traditional sensor tested, especially for water levels more than 0.05m. Calibration functions and sensitivity to water temperature were also assessed.
