Abstract
A novel intravenous dripping monitoring system is proposed and demonstrated. The system employs a multimode optical fiber-based and low-cost LiDAR. By using an ESP32 microchip, a TF-mini-s LiDAR module is controlled. Both devices are embedded in a 3D-printed casing, and by using a multimode optical fiber coupler, the system interacts with a typical intravenous system. This interrogator configuration has a high-resolution time of 20 ms, a good signal-to-noise ratio (<13 dB), low power consumption, and maximal flow rate monitoring of 93 drops per minute. The proposed system is a novel-intensity LiDAR application that can be applied in micro-fluidics, agriculture, and drug delivery monitoring.
