It is a low-power, long-range wireless protocol that enables the transmission of small data packets over long distances with low power consumption, making it ideal for IoT applications that require low data rates and long-range connectivity.</p> <p>LoRaWAN operates in the unlicensed spectrum and uses chirp spread spectrum modulation to enable long-range communication while maintaining a low power consumption. The LoRaWAN protocol also uses a star topology, where individual end devices communicate with a central gateway, enabling the network to cover large areas with minimal infrastructure.</p> <h3><strong>The LoRaWAN protocol has several features that make it suitable for a wide range of IoT applications, including:</strong></h3> <ol> <li><strong>Long range</strong>: LoRaWAN can transmit data over several kilometers/miles in an urban environment and up to tens of kilometers in rural areas, providing wide coverage with minimal infrastructure.</li> <li><strong>Low power consumption:</strong> LoRaWAN devices can operate on battery power for years, making them ideal for IoT applications where frequent battery replacements are not practical.</li> <li><strong>Low cost:</strong> LoRaWAN is a low-cost solution, as it uses unlicensed spectrum and requires minimal infrastructure to operate.</li> <li><strong>Secure:</strong> LoRaWAN provides end-to-end encryption, ensuring secure communication between devices and the central gateway.</li> </ol> <p>LoRaWAN is used in a variety of IoT applications, such as smart cities, industrial automation, smart agriculture, and asset tracking, where long-range, low-power connectivity is essential. Overall, LoRaWAN is a key technology in the LPWAN ecosystem, providing a reliable and cost-effective way to connect a large number of IoT devices over long distances.</p> <p class="wpg-read-more"><a href="https://multitech.com/iot-wiki/lora-protocol-lorawan/">Read More</a></p></div>" href="https://multitech.com/iot-wiki/lora-protocol-lorawan/" >LoRaWAN</a>® Wireless Outdoor/Industrial Temperature Sensors

About the LoRaWAN® Wireless Outdoor/Industrial Temperature Sensors

LoRaWAN® Air Temperature and Humidity Sensor with External Probe for Outdoor/Industrial Use

This sensor uses air flow through a sintered porous stainless steel filter to allow for temperature and humidity measurements in outdoor and industrial environments. The sintered porous filter is IP54 rated to protect against dust and debris. This sensor can also be used for detecting freezing temperatures to protect plumbing, detect heat failure in second homes or remote buildings, detecting cooling system failures, and industrial temperature monitoring.

LoRaWAN® Temperature Sensor for Outdoor/Industrial Use

This sensor uses an external probe to measure temperatures. Ideal for food service, cold chain monitoring, restaurants, laboratory monitoring, server rooms and warehouses. If the temperature rises above or falls below the configured threshold, an alert is sent to the wireless network.

LoRaWAN® Thermocouple Temperature Sensor for Outdoor/Industrial Use

This sensor measures temperature using an external K-type thermocouple. Other thermocouples may be used and can be configured via downlink messages. Multiple thermocouple types supported: B, E, J, K, N, R, S and T. The enclosure is suitable for outdoor and industrial use. Applications include gas turbine exhaust, diesel engines, industrial processes, flame sensor, petroleum refineries, appliance heating, and food processing and production.
