DIWiFi is an IoT module designed for various types of digital output sensors. The internal IoT core plan developed by our company is dedicated to output signal referral, which can extend various types of digital output sensors to connect to the cloud or local network. Support Websocket and MQTTS communication protocol. The operation commands are collected in JSON format, with multiple built-in functions and options such as attribute access, permission management, event generation, and behavior scripts. System integration developers can directly obtain the switch status from the digital output form sensor from the network platform, and set the behavior script according to the system function requirements to easily complete the project. In addition to WiFi, other wireless network options such as NBIoT can be provided in the short term.
