4. SYSTEM PROGRAMMING
The two primary objectives of the system are: to collect stream data and to collect water
samples.
The program measures water depth every program cycle (60 seconds). If the depth is below
a threshold, then data from all sensors, including rainfall are logged every hour. If the depth
is greater than the threshold, data is logged every program cycle.
The program uses water depth, time or a sample counter to determine whether to collect a
sample.
A simplified flow chart of the standard system program is shown in Figure 8.
