My experiment consist in design and build a weather station.
Using the LattePanda, I´ll setup a weather monitor station, integration air quality, temperature, humidity and UV sensor. The information from the sensor will be sent to the cloud, the LattepPanda has a Wi-Fi interface that I will use to connect an external antenna using the RF connectors.
The main component of this design is the enclosure (1554VA2GYCL), Hammond provided this enclosure with the holes for the connectors already done, also they put their logo and element14 logo, which is really nice.
The lid is clear, this is helpful to see if there's any leak in the enclosure.
Three RF connectors were provide (SMA, TNC and N type).
Those will be used to connect an external Wi-Fi antenna.
Three IO connectors were provided (Ethernet, USB, 4-pin)
Those will be used to connected the external sensors and provide wired connection to the Internet.
The test plan is the following:
- Integration Test. Integrate all the connectors in the enclosure, here I want to know if all the connecters can be attached correctly to the enclosure and be sure that the seals of each one will work correctly.
- Ingress Protection Test. Check that the sealing is achieve, this test will be done without any electronics.
- Functionality Test. Integrate all the electronics inside the enclosure and external sensors and interfaces. Run the weather station in an indoor environment.
- Real Monitoring Test. Run the weather station in an outdoor environment. This will works as any other weather station but also a monitoring of the enclosure internal envaronen to detect any leak.
- Submersion Test. Run a submersion test of the weather station, this will be just a few centimeters just to check if the enclosure and connectors are capable to provide the required ingress protection.
- Accelerated Test. Test in a accelerated environment to check if the sealing is still working in the worst case scenario.
