#Special Updates: Here at Seeed, we’ve been working on developing industrial IoT products. And in this new series of blog posts, we will show you some behind-the-stage scenes of how these products are tested to meet the industry standards. In the previous posts, we shared the followings:
- IP66 dustproof and waterproof functions Testing
- High-low temperature testing after sharp temperature differences
- Long-range communication testing
- How we chose and tested different materials for the probe enclosure of LoRaWAN air temperature & humidity sensor and barometric pressure sensor
As SenseCAP LoRaWAN Light Intensity Sensor is expected to be deployed with direct exposure to sunlight, it’s highly important that both the data-logger and the sensor probe are durable in outdoor environments for a long time. Among the many details that we consider, I will share with you two aspects.
Cable to Board Connection FirmnessSenseCAP Light Intensity Sensor has a cable that connects the light sensor sphere to the PCB board, and the cable is encapsulated in a flexible coolant hose (the blue part). We took the following measures to test the sturdiness and durability. The connection was bent by 180 degrees, continuously for a minimum of 100 times. And all the products work perfectly after the tests.

Durability & Waterproof Function of the Light SphereThe light intensity probe is hidden in the sphere, which is connected to the flexible coolant hose. As mentioned above, the light intensity sensor is aimed for use in outdoor environments. We need to make sure this part is durable and waterproof. We had an A/B test with the following two designs.
- A: Glue a plastic foam to the connection part.
- B: Design a spiral metal structure for connection.
