Pi Zero W, IO Expansion HAT and analog Gravity sensors compatibility.

Hi, I'm planning a project that will use the following probes/sensors :



Gravity: Analog Electrical Conductivity Sensor /Meter V2 (K=1)


Gravity: Analog pH Sensor/Meter Kit V2

Gravity: Analog Turbidity Sensor for Arduino

Gravity: Analog ORP Sensor Meter for Arduino



I would like to use a Raspberry Pi Zero W I have no use for.


My question is, can I use all of the above sensors with the DFR0604  IO Expansion HAT for Raspberry Pi Zero/Zero W or do I have to use one DFR0553  Gravity: I2C ADS1115 16-Bit ADC Module for each analog sensor ?

Thanks in advance for your help !

The DFR0604 has 4 channel ADC, I think this fits your needs. You want to use four analog sensor on the Pi Zero W.

You don't have to use the ADS1115
