Sensors connection (DS18B20, and EZO pH and ORP)

Here the schema to connect DS18B20 and EZO circuits to the Raspberry pi GPIOs.

You can see what is the EZO circuit, what the carrier board, and what the probe...

Edit rpi config file with:

sudo nano /boot/config.txt

including this:

force_turbo=1
enable_uart=1
dtoverlay=pi3-disable-bt
# sencond UART1 /dev/ttyS0 
dtoverlay=uart1,txd1_pin=32,rxd1_pin=33
