In industrial automation, smart energy, environmental monitoring, and other fields, remote and real-time monitoring of DC voltage in on-site equipment is a common and critical requirement. Traditional wiring methods are costly and inflexible, while wireless and networked transformation has become the mainstream trend. Based on the rich product line of Chengdu Ebyte Electronic Technology Co., Ltd., this article will explain two standardized and highly reliable solutions for remote WiFi monitoring of DC voltage via WiFi networks.

In complex application scenarios such as industrial IoT, smart cities, and energy monitoring, stable, reliable, and long-range data transmission is critical to system success. Leveraging its profound technical expertise, EBYTE launches the flagship product of its industrial-grade wireless data radio series—the E90-DTU(400SL42).

In numerous fields such as the Internet of Things (IoT), vehicle navigation, precision agriculture, drones, and asset tracking, Global Navigation Satellite System (GNSS) modules are core components for achieving high-precision positioning, navigation, and timing. Faced with a market full of GNSS modules with varying functions and performance, selecting the most suitable model based on project requirements is a key challenge for engineers. This article will take Chengdu EBYTE's extensive product line as an example to systematically outline the core dimensions of GNSS module selection and provide a clear selection path.

Before starting the practical demonstration, we need to understand the rules for custom protocol forwarding of the ECAN-401​ device: Since the CAN frame format is message-based and the serial frame format is byte-transmission-based, the serial frame must fully comply with the custom protocol specifications, including all content defined in the configured mode

In IoT, smart wearables, industrial control, and other fields, Bluetooth (especially BLE) has become the mainstream technology for short-range wireless communication. Faced with a wide range of Bluetooth modules on the market, selecting the most suitable model based on project requirements is a critical decision for engineers in the early product development stage.

In the design of IoT, asset tracking, and portable navigation devices, the selection of Global Navigation Satellite System (GNSS) modules is critical. Among performance metrics, cold start time (the duration from full power-off/first power-on to successful positioning) is a key indicator directly affecting user experience and device response speed. For systems using FPGA as the main controller, interface compatibility, power consumption, and integration of the GNSS module are also essential considerations.

In IoT and embedded wireless communication projects, developers often need a powerful, interface-rich wireless core module that supports in-depth secondary development.

Detection devices typically require stable data transmission. We recommend a "Wi-Fi + LoRa" dual-mode backup or scenario-specific scheme to ensure communication reliability in complex environments, based on your needs for transmission distance and data rate.

In the documentation, the AM21 series and AM31 series AC-DC modules meet the input voltage requirements, with output voltage accuracy (output precision) typically at ±1% or ±5%—the ±1% precision models can satisfy the ≤±2% voltage stability requirement. Below are specific recommendations:
