Water Level Control System Based on PSoC

Abstract

The design adopts PSoC chip produced by Cypress Semiconductor Company to carry out circuit design and C language programming on the PSoC Creator 3.0 development platform, and displays the water level on the liquid crystal display through reading the electric signals transmitted by the water level sensor after ADC conversion and processing. If the water level is higher than the high value of preset warning water level, then LED1 light is on and emits a signal of gate opening; if the water level is lower than the low value of preset warning water level, then LED2 light is on and emits a signal of gate closing. For the designed capacitive touch circuit, the gate opening and closing is manually controlled by touching keys. Eventually, the program is compiled and downloaded to PSoC development board, so as to achieve manual and automatic control of water level on a single chip.
