What are the differences among the 2-, 3-, and 4-wire configurations of a PT100?
When selecting a PT100 sensor, it is also necessary to consider performance parameters such as its temperature range, response time, and stability to ensure it meets the requirements of the specific application. Additionally, during installation and operation, proper wiring and calibration procedures must be followed to guarantee the accuracy and reliability of the measurement results.

Why do you need a LoRaWAN server when purchasing a LoRaWAN gateway?
A LoRaWAN gateway directly forwards received LoRaWAN data to the LoRaWAN server, and this process requires the LoRaWAN server. This is because LoRaWAN employs a star‑topology wireless network architecture that includes end nodes, gateways, a network server, and an application server—forming a hierarchical flow from LoRaWAN end nodes, through LoRaWAN gateways and the LoRaWAN server, to the cloud platform.

Are PT100 and PT1000 interchangeable?
Can PT100 and PT1000 sensors be used interchangeably? This is a question frequently asked in the fields of industrial automation and temperature measurement. Although both are platinum resistance temperature detectors with similar operating principles, direct interchangeability is not straightforward, as it depends largely on the specific requirements of the application environment and the differences in sensor characteristics. If an existing measurement system or device is designed for PT100, replacing it with a PT1000 could lead to compatibility issues—ranging from circuit matching and signal processing to display calibration. Therefore, in most cases, to ensure system stability and accuracy, it is not advisable to swap these two types of sensors without careful consideration.
