Need to measure how well chronically ill patients are sleeping through the night?

• Weigh them while they are on the bed to see if they are losing or gaining weight?
• Want to see if they are restless at night?
• Did they wake up and get out of bed at night?
• How many times did they toss and turn?
• Export data into excel for plotting/charts and analysis.
