S31-LS LoRaWAN Temperature and Humidity Sensor Node 868MHz with Solar

The S31-LS from Dragino is a state-of-the-art sensor node for LoRaWAN, specially designed for outdoor use. This model utilizes a combination of solar cells and a supporting battery to ensure optimal performance and longevity in the open air. It integrates the precise SHT31 temperature and humidity sensor from Sensirion, which is housed in a waterproof casing, making it ideal for long-term use under variable weather conditions. The S31B-LS operates in the 868 MHz frequency range and uses the SX1262 LoRa Core, known for its wide-ranging transmission capacity and low energy consumption. These characteristics allow reliable data communication over long distances with minimal power consumption. The built-in 48 MHz ARM microcontroller, along with 256KB flash and 64KB RAM, ensures that the sensor node can handle even the most demanding industrial IoT applications. For easy maintenance and configuration, the S31-LS supports Bluetooth V5.1 for local settings as well as OTA updates via LoRaWAN, allowing firmware updates to be performed wirelessly. The sensor comes with pre-installed, unique LoRaWAN keys, enabling fast and secure connection to the network.
