temperature-lcd-display

Temperature Monitor I made to monitoring the temperature of broodling quail chicks.

Parts:

• Raspberry Pi Zero (non-wireless because I had a spare non W version lying around and those are practically useless for most projects)
• ds18b20 temperature sensor (left over from Uni and 1-wire is an awesome interface to work with on the pi)
• 16x2 LCD Display Module (I wish I had an i2c module to cut down on wires)
• Raspberry Pi Zero LCD Brackets (3d printed, designed by by clarionut;found here)

Setup:

• Add dtoverlay=w1-gpio to /boot/config/ to enable 1-Wire kernel module
• Add dtoverlay=dwc2 to /boot/config.txt and modules-load=dwc2,g_ether after rootwait in /boot/cmdline.txt to the enable OTG Ethernet module (for debugging since we don't have wifi)
• pip install PILCD
