python - Connect a pressure sensor with Raspberry Pi 2 ...

· Raspberry pi does not have any Analog input so you will need an external ADC. Your sensor is 5V, so go with a 5V torrent ADC. you can use ADS1115 because it has 4 ADC channels so you can connect upto 4 sensor to one board. it has inbuilt voltage ref so you dont need any external Vref. its a 16 bit ADC so your readings will be highly accurate. it also has gain multiplier. its input are 5V torrent.
