Monitoring application

This section details ways to automate measurement acquisition in order to set up the OhmPi as a monitoring tool.

Repeated acquisition at fixed intervals

The easiest way to set up time-lapse acquisition is to perform repeated acquisition of a sequence at fixed intervals. Repeated acquisition can be initiated from the three different Interfaces.

Example of code for monitoring.

### Run multiple sequences at given time interval
k.settings['nb_meas'] = 3  # run sequence three times
k.settings['sequence_delay'] = 100 # every 100 s
k.run_multiple_sequences()  # asynchron
# k.interrupt()  # kill the asynchron sequence

Scheduled acquisition using crontab
