I am select ads1115 for Mycodo input, i can use Input Configuration: ADS1115: Generic Analog pH/EC, and
Are you saying that I can connect a sensor from another manufacturer other than the Astra sensor?
I don’t know what Astra is, but that input is designed for analog pH/EC sensors that return a voltage relative to the measured pH or EC.
The ec,ph sensor I have is not an anyleaf or atlas product, but the lines are vcc,gnd,nc,sig, can i connect to ads1115 and be compatible with mycodo?
Can only vcc.gnd.sda.scl be connected to ads1115?
Only circuits or devices that output a voltage can be used with an analog-to-digital converter (ADC) to measure that voltage.
It does not make sense to ask if the SDA and SCL lines of an I2C communication protocol can be connected to an ADC. ADCs measure analog signals (voltages) and I2C is a digital protocol.
DFR Robot’s Gravity: Analog pH Sensor / Meter Pro Kit V213 for pH, the Gravity: Analog Electrical Productivity Sensor / Meter V2 (K=1) 9 for EC can be used by connecting to ads1115 and selecting as shown below in the setup-input-Generic analog ph/ec?
Yes, it should work, as long as it is analog.
