ADS1115 with water pressure sensor
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
To improve accurate and stable for output data from sensor, can we use :
Gravity: I2C 12-Bit DAC Module for changing Analog Current to Voltage Converter(for 4~20mA Application) ?
And how can we connect to sensor, someone know please help !
Hi
From my understanding, if the output of your sensor is an analogue signal, an ADC (just like ads1115 as you mentioned) can help to increase the accuracy and stability by over-sampling and higher bit rate, not a DAC.
If what you are looking for is an ADC, you can connect your sensor to the A0-A3 port on the ads1115 board, and connect ads1115 with your development board via the I2C channel.
Here is the Wiki page for reference.
