The examples provided are based on the STM32F103RBT6 and the STM32H743, the connection provided is based on the STM32F103RB.
If you want to use other STM32 boards, please change the connection and you may need to port the codes yourself.
Hardware connection
Liquid | STM32 | Description |
---|---|---|
VCC | 3.3V | Power input |
GND | GND | Ground |
AOUT | PA6 | Analog data output |
Examples
The examples are based on the HAL library. Please download the demo codes, unzip them and find the STM32 examples.
- Open the project from Liquid-Level-Sensor-code\STM32\STM32F103RB\MDK-ARM by Keil.
- Build the project and program it to the STM32 board.
- connect the UART1 of the STM32 board to the PC and check the serial data by SCCOM software.
Expected result
When the module is inserted into water, the serial port outputs data. The higher the water level, the greater the data.
