4.7.2.2. Using the Data Logger Firmware
The Data Logger firmware runs on an MCU card where it logs temperature and humidity data. The Data Logger
firmware also generates alarms if the temperature or humidity become too high or too low.
The user interface for the Data Logger firmware uses buttons, LCD displays, and an output pin to sound a buzzer.
The Data Logger firmware is normally in sleep mode. In sleep mode, the firmware enters low-power mode between
samples; the LCD is blank, and buttons S1–S3 do not work. In awake mode, the firmware does not enter
low-power mode; the LCD is not blank, and the buttons work normally.
4.7.2.2.1. Buttons
The Data Logger firmware uses three buttons and an LED as shown in Figure 21.
