Humidity tests for electronics

Humidity tests with fan

Today we tested whether the fan can sustain a high humidity in our experiment. Due to the agar and the plants the relative humidity inside our experiment can exceed 100% so that condensing water occurs. This can be bad for electronical components in general so we have to find a solution for this problem!

Experiment setup Experiment setup closed CO2-Sensor breakout board for internal testing with status LED when a measurement is happening

For this test, we first sealed the fan with a hot glue gun. Then we poured some hot water inside a box and placed our fan in it on a small platform. The fan was running at full power! We closed the box and in a short time we saw some water droplets condense on the walls of the box. The fan continued to run normally! Overall the test was successful and increased our confidence in our design.

Testing of CO2-Sensor

At the same day we tested our CO2-Sensor and built a small breakout board. With this board we can easily connect it to our breadboard for easy testing. The sensor worked fine and we were able to read our first values!
