| + | ===== Power Consumption ===== | ||
| + | |||
| + | Prototype draws 3.2mA average and spikes at 4.5mA on an Arduino Uno with Serial Connection activated and lighting the screen 100% of the time and with no deep sleep implemented. | ||

| + | ===== Potential Upgrades ===== | ||
| + | |||
| + | *Build a lightweight version running an attiny with a pushbutton to display the data | ||
| + | *Build a 3D casing for it | ||
| + | *Check autonomy on a battery | ||
| + | *Add an RTC for timestamping the data | ||
| + | *Swap the UNO for an upgraded card with WiFi connectivity and upload the data to a server | ||
| + | *Make graphs from uploaded data | ||
