Raspberry Pi GPIO header

The following screenshot is a chart of the GPIO pins of the Raspberry Pi Zero. In this case, we will use the SPI configuration interface (SPI_MOSI, SPI_MISO, SPI_CLK, SPI_CE0_N):

The following diagram shows the name of the pins of the MCP3008 chip that you connect to the Raspberry Pi: 

The following image shows the temperature sensor:

You need to connect the following pins according to the next description:

• VDD to 3.3 volts

• VREF to 3.3 volts from the Raspberry Pi Zero

• Pin AGND to GND

• Pin CLK (clock) to GPIO11 of the Raspberry Pi

• DOUT to GPIO9

• Pin DIN to GPIO10

• Pin CS to GPIO8 and the pin

• Pin the MCP3008D GND to Ground

This connection is represented in the following figure:

The following image shows the connections of the sensor to the ADC MCP3008 and the Raspberry Pi:

Reading the data with a Python script

In the next section, you will create the MCP3008.py file; you need to follow the next steps:

1. Open the terminal on your Raspberry Pi Zero.

2. Enter the interface in your Pi terminal...
