Kickstarter Enables Building LoRa IoT Gear in 3 Steps

Electronic Cats has launched a Kickstarter campaign called LoRaCatKitty to enable the building of Internet of Things (IoT) applications with LoRa in just three steps. LoRaCatKitty is designed to simplify the development of IoT applications using LoRa technology. It has based its development on the ESP8266 WiFi module and the LoRa RN2903 or RN2483 Microchip module.

LoRAKitty

The mobile application for LoRaCatKitty, allows you to generate and compile the firmware in the cloud and use your smartphone to transfer and the firmware to the board. All the necessary hardware libraries are accessible through the app so you can select, download and transfer them to your LoRa device directly. The solution uses Grove connectors that allow easy and quick use of sensors, actuators or external elements without the need for soldering. Users can just connect the blocks and build their project. LoRaCatKitty supports a long list of sensor modules with Grove connectors.

The LoRaCatKitty app for Android is used to wirelessly program the device and will allow beginners to develop an infinite number of applications in an easy and intuitive way. LoRaCatKitty is completely compatible with LoRaWAN platforms like The Things Network, Beelan and others, allowing you to access RESTful API resources which can be used to develop IoT apps easily with the sensors and actuators visualized.

Semtech’s LoRa Technology Enables Rural IoT Network for Farmers

Semtech has announced its collaboration with National Narrowband Network Communications (NNNCo) to build a nationwide rural IoT network to bring high-tech agriculture solutions to Australian farmers. The LoRaWAN open standard developed by the LoRa Alliance is expected to help transform Australia’s farms, giving farmers real-time data on soil moisture, rainfall, crops, water levels, and livestock through a network of in situ low-cost wireless sensors. One of the key comptabilities of a LoRaWAN is that it enables users to communicate bi-directionally with sensors on an individual or group level.

The sensors use limited power and can operate ‘in the field’ for years without the need for intervention. The farmer will be able to make intelligent, sound decisions to drive multiple functions, including irrigation, livestock feed stations, water pumps, and emergency signals. The LoRaWAN network will immediately cover one million acres of farmland across rural New South Wales (NSW) which will encompass dry land crops, horticulture and livestock and a number of rural towns. Within 18 months, the plan is to extend broadly across Australia.

Semtech’s LoRa wireless RF technology is a widely adopted long-range, low-power solution for IoT that gives telecom companies, IoT application makers and system integrators the feature set necessary to deploy low-cost, interoperable IoT networks, gateways, sensors, module products, and IoT services worldwide. IoT networks based on the LoRaWAN specification have been deployed in over 50 countries.

Small Antenna Covers Bands for LPWAN, IoT and Smart Cities

Antenova has announce a new antenna, Grandis, part number SR42I010. It is an SMD antenna that is physically smaller yet provides enhanced performance in the 863-870 MHz and 902-928MHz bands. It directly targets the growing number of M2M and IoT applications using the LPWAN protocols. With Grandis, Antenova has reduced the footprint of the LPWAN antenna to 12.0 x 11.0 x 1.6mm, while also enhancing the antenna’s performance. Grandis is a low-profile antenna which uses a ground plane to radiate, and is designed to be placed in the corner of the PCB.

Antenova Grandis SR42I010

Antenova endeavours to give PCB designers the benefit of flexibility in the positioning of the antenna within a design, so the Grandis antenna is supplied is two versions, Left and Right, to give designers a choice of locations for the antenna on a PCB. LPWAN is an increasingly popular choice for IoT and smart city applications because it uses less power, which means that the batteries within individual devices will have an extended life. Antenova’s Grandis antenna covers the newer LPWAN standards for connected devices in IoT and smart cities: LoRa, SigFox and Weightless-P. Grandis is suitable for all applications in the 863-870 MHz and 902-928MHz bands, so it could be used in industrial, scientific and medical applications, smart metering, network devices, manufacturing automation, agricultural and environmental monitoring and consumer tracking, worldwide.

PW1-928 RF Data Transceiver Module

The PW1-928 RF transceiver module is intended for the reliable bidirectional transfer of digital data over distances of over 300′ in cluttered urban environments (more than half a mile in true line of sight). The module—which operates in the 902-to-928-MHz frequency band—generates a nominal 7 dBm into a 50-Ω load and achieves an outstanding RX sensitivity of –112 dBm.Lemos can 1

The module uses the industry standard LoRa direct sequence chirp spreading protocol combined with a proprietary data structure to both simplify user implementation and to significantly improve packet transmission reliability. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be directly connected to typical microcontrollers, RS-232 converters, or USB adaptors. The module automatically handles all radio functions resulting in a true UART-to-antenna wireless link. Configuration setup is also accessed through the UART interface.

The module is well suited for a variety of applications, including asset tracking, remote data logging, and industrial/home automation. Features:

  • True “asynchronous UART to antenna” solution
  • Direct sequence (chirp) spread spectrum
  • 9.6-kbps user payload data rate
  • Uses highly robust augmented LoRa protocol
  • Low power standby and TX-from-standby modes
  • Adjustable output power
  • User programmable address and channel-group
  • 3.3-V logic I/O
  • Digital RSSI (read via serial port)
