All data moving to the Cloud, or vice versa goes through the gateway, which can be either a dedicated hardware appliance or software program. IoT GatewayĪn IoT Gateway, according to TechTarget, is a physical device or software program that serves as the connection point between the Cloud and controllers, sensors, and intelligent devices. The Arduino Sense is an excellent, low-cost single-board microcontroller for learning about the collection and transmission of IoT sensor data. Gesture, Proximity, Light Color, and Light Intensity Sensor ( APDS9960): Advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS), and Color Sense (RGBC).Microphone ( MP34DT05): MEMS audio sensor omnidirectional digital microphone.Barometric Sensor ( LPS22HB): MEMS nano pressure sensor: 260–1260 hectopascal (hPa) absolute digital output barometer.Humidity and Temperature Sensor ( HTS221): Capacitive digital sensor for relative humidity and temperature.9-axis Inertial Sensor ( LSM9DS1): 3D digital linear acceleration sensor, a 3D digitalĪngular rate sensor, and a 3D digital magnetic sensor.The Sense also contains an impressive array of embedded sensors:

The 3.3V AI-enabled Arduino Nano 33 BLE Sense board ( Amazon: USD 36.00), released in August 2019, comes with the powerful nRF52840 processor from Nordic Semiconductors, a 32-bit ARM Cortex-M4 CPU running at 64 MHz, 1MB of CPU Flash Memory, 256KB of SRAM, and a NINA-B306 stand-alone Bluetooth 5 low energy (BLE) module. I have used an Arduino single-board microcontroller as an IoT sensor, actually an array of sensors. In the following hands-on post, we will explore the use of the LoRa and LoRaWAN protocols to transmit and receive sensor data, over a substantial distance, between an IoT device, containing a number of embedded sensors, and an IoT gateway.įor this post, I have used the following hardware. This means that the signal can potentially reach as far as the horizon, as long as there are no physical barriers to block it. LoRa’s range depends on the “radio line-of-sight.” Radio waves in the 400 MHz to 900 MHz range may pass through some obstructions, depending on their composition, but will be absorbed or reflected otherwise. On average, in an urban environment with an outdoor gateway, you can expect up to 2- to 3-km-wide coverage, while in the rural areas it can reach beyond 5 to 7 km. According to the Electronic Design article, 11 Myths About LoRaWAN, a typical LoRaWAN network range depends on numerous factors-indoor or outdoor gateways, the payload of the message, the antenna used, etc. However, according to other sources, it is generally more limited. LoRaWAN is often cited as having greater than a 10-km-wide coverage area in rural locations.

The MAC sublayer and the logical link control (LLC) sublayer together make up layer 2, the data link layer, of the OSI model. LoRaWAN is a cloud-based medium access control (MAC) sublayer (layer 2) protocol but acts mainly as a network layer (layer 3) protocol for managing communication between LPWAN gateways and end-node devices as a routing protocol, maintained by the LoRa Alliance. LoRa enables long-range transmissions with low power consumption. LoRa uses license-free sub-gigahertz radio frequency (RF) bands, including 433 MHz, 868 MHz (Europe), 915 MHz (Australia and North America), and 923 MHz (Asia). The physical layer defines the means of transmitting raw bits over a physical data link connecting network nodes. Long Range ( LoRa), the low-power wide-area network (LPWAN) protocol developed by Semtech, sits at layer 1, the physical layer, of the seven-layer OSI model (Open Systems Interconnection model) of computer networking.
According to Wikipedia, LoRaWAN defines the communication protocol and system architecture for the network, while the LoRa physical layer enables the long-range communication link. LoRa and LoRaWAN permit long-range connectivity for the Internet of Things (IoT) devices in different types of industries. LoRaWAN is designed from the bottom up to optimize LPWANs for battery lifetime, capacity, range, and cost.
LoRa for IoT: Getting Started with LoRa and LoRaWAN Protocols for Low Power WAN of IoT IntroductionĪccording to the LoRa Alliance, Low-Power, Wide-Area Networks (LPWAN) are projected to support a major portion of the billions of devices forecasted for the Internet of Things (IoT).
