Getting Started with LoRaWAN on SenseCAP K1100 sensor prototype kit (Part 1)

SenseCAP K1100 review LoRaWAN sensors

CNXSoft: This getting started guide/review of the SenseCAP K1100 sensor prototype kit is a translation of the original post on CNX Software Thai. The first part of this tutorial describes the kit and shows how to program it with Arduino to get sensor data to a LoRAWAN gateway and display it on Wio Terminal, before processing the data in a private LoRaWAN network using open-source tools such as Grafana. The second part – to be published later – will demonstrate the AI capability of the kit. In the digital era where IoT and big data are more prevalent, a large amount of data is required to be collected through sensors. To enable the digital transformation, SeeedStudio’s SenseCAP K1100 comes with all necessary sensors and equipment including the Wio Terminal, AI Vision Sensor, and a LoRaWAN module. With this plug-and-play platform, makers can easily create DIY sensors for data collection and […]

Dragino RS485-LN Brings LoRaWAN Connectivity to RS485 Sensors

RS485 LoRaWAN

RS485 sensor nodes are often used in smart agriculture, environment monitoring, or factory & building automation and work up to 1.2 km when using AWG 18 cables. If you already have such nodes but need to extend the distance, or would like to reduce the need for long cables, you could make use of Dragino RS485-LN RS485 to LoRaWAN converter which will work up to 10+ kilometers depending on conditions. Dragino RS485-LN key features & specifications: MCU – STMicro STM32L072CZT6 Arm Cortex-M0+ microcontroller MCU @ 32 MHz with 192 KB Flash, 6 KB EEPROM, 20 KB RAM Connectivity LoRaWAN Via SX1276 LoRa transceiver Frequency Range: Band 1 (HF): 862 ~ 1020 MHz Band 2 (LF): 410 ~ 528 MHz Bands – CN470/EU433/KR920/US915/EU868/AS923/AU915/IN86/RU864 168 dB maximum link budget. +20 dBm – 100 mW constant RF output Programmable bit rate up to 300 kbps.

Dragino LHT65 is a $30 LoRaWAN Temperature & Humidity Sensor

LHT65 LoRaWAN Temperature & Humidity Sensor

If you’d like to monitor temperature and/or humidity in remote locations, one way is to get a LoRaWAN gateway, and setup a few LoRaWAN nodes connected to your own temperature & humidity sensors, and add a battery and enclosure. But if you’d like to save some time, and get a turnkey solution, Dragino LHT65 LoRaWAN temperature & humidity sensor may be an option. The sensor comes with an internal SHT20 sensor, and as well as an external DS18B20 waterproof temperature sensor. Features & specifications: LoRa Connectivity Frequency Bands  – CN470, EU433, KR920, US915, EU868, AS923, AU915 LoRaWAN Class A protocol Sensors Sensirion SHT20 (internal) Temperature – Range: -40 ~ 125 °C; 0.1°C resoultion; +/-0.3°C accuracy; long term drift < 0.02 °C/yr Relative Humidity – Range: 0 to 100%; resolution: 0.04%; accuracy +/-0.3%; DS18B20 (external) – Range: -55 °C~ 125 °C; resolution: 0.0625 °C; +/-0.5°C accuracy from -10°C to +85°C; +/-2°C […]

Dragino LoRaST M.2 LoRa Card Convert Compatible Platforms into LoRa Nodes

Dragino LoRaST

Modern motherboards or single board computers often expose mPCIe or M.2 / NGFF socket, and we’ve seen it was possible to easily add a LoRa radio using RAK833 mPCIe LoRaWAN gateway card to hardware with an mPCIe (USB/SPI) socket. You can now do something similar with Dragino LoRaST M.2 LoRa card by inserting into a spare M.2 / NGFF socket. There’s an important distinction however, as while RAK833 is designed for LoRa gateways, LoRaST is based on SX1276/SX1278 for LoRa end nodes. Dragino LoRaST M.2 LoRa card specifications: MCU – STMicro STM32L072CZT6 Arm Cortex M0+ MCU @ 32 MHz with 192 KB flash,  20 KB of RAM, 6 KB data EEPROM LoRa Connectivity Semtech SX1276/78 LoRa Wireless Modem Available Bands – 433/868/915/920 Mhz Built-in antenna or optional external antenna via I-PEX connector Host interface – Standard M.2 (NGFF) interface Supply Voltage – 1.8V ~ 3.6V Dimensions – 22 x 42 […]

Dragino NB-IoT Bee is a $23 Xbee Compatible NB-IoT Add-on Board

Several companies are already offering XBee NB-IoT add-on board including Digi International themselves, and SODAQ with their NB-IoT Bee N211 module going for 69 Euros. Dragino NB-IoT Bee is another option for NB-IoT connectivity using Xbee form factor,  and the board should be cheaper than most as it goes for $23.00 on Tindie with an external antenna. NB-IoT Bee specifications: NB-IoT module Quectel BC95-B5 for B5:850Mhz, B8:900Mhz, or B20:800Mhz in respectively Nb-IoT Bee QB05, QB08, QB20 models (i.e. one frequency is supported by model) Quectel BG96 for  LTE Cat M1 & Cat NB1 & EGPRS in Nb-IoT Bee QG96 model Output Powe  – 23dBm Sensitivity – -129dBm Micro SIM Slot Input voltage – 4.5v ~ 5.5V Temperature Range – -40°C ~ +85°C Typical applications for such board include smart metering, facility management services, security & fire alarms, asset tracking, smart city infrastructure and so on.
