Abstract
Monitoring environmental conditions in a testing laboratory can be a nuanced activity. Depending on the test conditions required by the IEC or ISO standard to which a particular device is being tested, as well as the specific t ests in question, the need for robust environmental sensing and data storage is mandatory. This paper will review one method that is being used at some unnamed IEC / ISO 17025 certified test lab and propose a possible solution for exploration utilizing Microelectromechanical system (MEMS) based environmental sensors and Low Power Wide Area Networks (LPWAN) for Internet of Things (IoT) devices using the LoRaWAN open standard protocols. Tests confirmed t he s uccess o f o ur design with high LoRaWAN reliability.
