Ticket #529, comment 6
initial v1 1 1 Design notes: 2 2 3 1. A server should be set up to regularly collect temperature and humidity values from the different lab sensors, and store the values in a database. As there is no strong dependence between general steps in the lab work and the lab environment data, the latter should be stored in a different database, possibly using a different (simpler) database management system than is used for BASE/Reggie. However, an API should be created to make it easy to retrieve data from the lab environment database .3 1. A server should be set up to regularly collect temperature and humidity values from the different lab sensors, and store the values in a database. As there is no strong dependence between general steps in the lab work and the lab environment data, the latter should be stored in a different database, possibly using a different (simpler) database management system than is used for BASE/Reggie. However, an API should be created to make it easy to retrieve data from the lab environment database, in order to investigate dependencies between individual lab steps in the lab work and the laboratory environment. 4 4 2. The lab environment database should store the following data for a lab sensor measurement:[[BR]]a. Lab sensor number (uniquely coupled to a sensor URL)[[BR]]b. Measurement date/time[[BR]]c. Temperature in °C[[BR]]d. Humidity in %.[[BR]] 5 5 3. The tests revealed that the response from a sensor came in a small fraction of a second (of the order of 0.2-0.4 seconds), but the time stamps obtained from the responses of the different sensors could differ more than a minute from each other and the system time of the server, where the test program was executed. In order to simplify investigation of environment measurements from different labs at specific time points, it is recommended that the server system time is used, when a time is stored for a measurement.
