产品概要
描述
The STDES-NBIOTLIGHT is a reference design for a multiboard smart street lighting application, consisting of a bottom, relay, and top boards.
A bottom board is supplied from a 90-220V AC mains input and is responsible for powering the rest of the system. RMS voltage and current, as well as active, reactive, and apparent power of the mains are measured by the STPM32, which uses UART interface to communicate with a STM32G071GB microcontroller. This microcontroller also manages the relay circuitry used for lamp on/off control and dimming, according to commands received from the top board or an online dashboard.
The metering data and lamp-control signals are galvanically isolated using the STISO621 digital isolator, ensuring robust isolation and high-speed data transmission between the bottom and top boards.
The top board includes another STM32G071GB microcontroller, which acquires data from the on-board LIS2DUX12 accelerometer and interfaces with the ST87M01 LTE Cat NB-IoT module to both send and receive the street lighting data over the internet.
An online server and web dashboard was developed for monitoring the street lighting data, providing real-time visualization of metering and acceleration data, as well as dimmer lamp values.
The ST87M01 communicates with the server using the TCP and UDP protocols, allowing the user not only to monitor but also to remotely control the lamp state and dimmer level.

性能一览
- Metering measurements based on STPM32, providing high‑accuracy RMS values of voltage and current
- Active, reactive, and apparent power and energy, using up to four independent 24‑bit, 2nd‑order sigma‑delta ADCs
- STISO62x digital isolators: galvanic isolation with high‑speed data transmission on the UART interface, robust protection against electrical noise
- Two STM32G071 microcontrollers use a high-performance Arm Cortex®-M0+ 32-bit RISC core. They operate at speeds of up to 64 MHz.
- Suitable for Internet of Things (IoT) applications
- On‑board LIS2DUX12 3‑axis linear MEMS accelerometer with an internal temperature sensor, enabling embedded functions such as tilt detection and significant‑motion detection
- Online dashboard for metering and MEMS data, enabling remote lamp dimmer control over the internet thanks to ST87M01
- ST87M01: high‑performance, ultracompact, and low‑power LTE Cat NB‑IoT industrial module supporting the TCP and UDP protocols for data streaming
- Powered by VIPER222 high performance and high-voltage converter. It eliminates the need for additional components in the BOM thanks to its high-voltage startup and current sense circuit
