Using STM32 as the control module,high-precision capacitive water level sensor as the sens-ing probe,accurate measurement of urban road water level is achieved combined with 24 bit high-pre-cision analog-to-digital conversion chip ADS1218.The wireless transmission module EC20 R2.1 is used to transmit water level data from each measurement node to form a high-precision urban road water level monitoring network.
