3 MSP430FR2533 Liquid Level Measurement Application

This chapter uses CapTIvate Design Center to complete the design of the liquid detection system. Based on this, the MSP430FR2533 hardware platform for liquid level detection and system algorithm writing are completed. Meanwhile, different electrode connection and measurement method comparison tests are carried out. Finally, for the issue of large error at low heights, a software optimization method is introduced.
