This is a test channel for my Junior Design class. The field in use represents data gathered from a camera in one of the parking lots at Bucknell University. The idea is to show, in a span of a week, how populated the lot is.
Raspberry BCM2711-CPU's temperature monitor. Data reading from the /sys/class/thermal_zone file. The RasPi pin GPIO4 connected an Dallas DS18b20 sensor. Field-2 present the room temperature. Channel update every two minutes.
