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

29/08/2016· 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.

Read Raspberry Pi Computing: Gas Sensors | Leanpub

We’ve assembled our Raspberry Pi with a gas sensor and an analog to digital converter. We installed an operating system and configured it for use. We’ve set up networking and installed a database and a web server. We’ve written code to record data into our database and an API to pull data out of it. We’ve even installed a graph to display it in a visual form. Nice work.

Using Sensors with a Raspberry Pi -

Sensors are another type of input that can be connected to the Raspberry Pi. They may gather data about, for example, light or temperature conditions, but fundamentally they work in a similar way to the push button: they provide different input to the Pi depending on something that is happening externally.
