S31B-LS LoRaWAN Temperature and Humidity Sensor Node 868MHz with Solar
The S31B-LS from Dragino is a state-of-the-art sensor node for LoRaWAN, specially designed for outdoor use. This model uses a combination of solar cells and a supporting battery to guarantee optimal performance and durability in the open air. It integrates the precise SHT31 temperature and humidity sensor from Sensirion, which is housed in a waterproof enclosure and is therefore 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 far-reaching transmission capacity and low power consumption. These features enable 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 S31B-LS supports Bluetooth V5.1 for local settings as well as OTA updates via LoRaWAN, allowing firmware updates to be carried out wirelessly. The sensor comes with pre-installed, unique LoRaWAN keys that enable a quick and secure connection to the network.
