Autonomous wireless multi-sensor nodes powered by PV batteries and based on wireless LAN

STDES-IDS002V1

Overview

The STDES-IDS002V1 kit is a complete, fully configurable energy reference design wireless sensor node powered by a photovoltaic module soldered on the top. It consists of a fully integrated STDES-ERH003V1 transmitter board with on-board temperature sensor (STTS751), air pressure sensor (LPS25H) and 3-axis accelerometer MEMS sensor (LIS3DH), powered by the SPV1050 device. An ST microcontroller and Sub-1 GHz RF transmitter are also embedded.

The system includes an STDES-ERH002V1 receiver companion board based on the STM32L151), powered through a USB cable from the PC. The reference design kit is supported by a user-friendly software GUI able to display the electrical characteristics, conversion efficiency, MPPT accuracy of the PV module and battery, as well as sensor readings.
