Putting the system to the test

Friday, October 11th 2019

Report and pictures: Medard Honfo, Katrijn Baetens

After several days of preparation, a stable system was developed so we have the confidence to put the system to the test on the lake itself. After the last verifications our team (Zacharie Sohou, Katrijn Baetens, Medard Honfo, Sylvain Amoussou) and Mr Victor Okpeitcha,an oceanographic ingeneer of IRD/IRHOB took “une pirogue”, a local type of boat, to deposit three thermometers. The stations were next to existing stations of IRD/IRHOB, this will help the validation of our system and avoid double work.

Map of the positions were the sensors are released.

Station 1 (yellow) in the middle of the canal.

station 2 (orange) in the middle of the lake, this was not evident, luckily we got help from local fishermen

Station 3: A permanent station installed by IRD/IRHOB (blue)

Methodology used to install the sensors:

Step 1: fix a perforated pipe in the water

Step 2: Put the sensor inside, the sensor will float on the water

Step 3: close the system and put a lock on it
