与化学法相比，吸收光谱法可以实时监测化学需氧量（COD），无污染。然而，在开放水域进行低功耗、长期、快速、准确的COD监测存在重大挑战。本研究提出了一种具有低功耗、长期实时监测能力的COD传感器。灵敏度为0.0083(mg/L)$^{-1}$，分辨率为0.08mg/L，仪器一个周期的功耗约为0.0505mAh。为了提高COD传感器的测量精度，研究了温度和自然光对测量的影响，并提出了补偿方法。后湖实验结果表明，温度和自然光补偿后测量误差小于补偿前的5 mg/L，小于1.6 mg/L。
Compared with the chemical method, absorption spectroscopy can be used to measure chemical oxygen demand (COD) in real-time monitoring without pollution. However, there is a significant challenge in performing low-power-consumption, long-term, fast, and accurate COD monitoring in open waters. In this study, a COD sensor with low-power-consumption, long-term, real-time monitoring capabilities is proposed. The sensitivity is 0.0083 (mg/L) $^{-1}$ , the resolution is 0.08 mg/L, and the power consumption of the instrument in one cycle is approximately 0.0505 mAh. To improve the measurement accuracy of the COD sensor, the influence of temperature and natural light on measurements was studied, and a compensation method is proposed. Experimental results in the Back Lake indicate that measurement error is less than 1.6 mg/L after compensation of temperature and natural light compared with 5 mg/L before compensation.
