Using SenseCAP T1000 LoRaWAN GPS Tracker for cattle tracking

SenseCAP T1000 Review Smart Agriculture Cattle Tracking

SenseCAP T1000 is a credit-size GPS tracker using LoRaWAN low-power long-range connectivity. Smart Agriculture is one specific application that can leverage IoT and LoRaWAN to analyze and manage soil, crops, and water, but also to track the location of livestock. This is an important aspect of farming, and we’ll use the SenseCAP T1000 LoRaWAN GPS tracker to track cattle in this article/review. SenseCAP T1000 unboxing The package contains the SenseCAP T1000 GPS Tracker device, which is about the size of a credit card, and a charging cable. Smart cattle tracking with SenseCAP T1000 LoRaWAN tracker Here are some of the benefits and features of Smart cattle tracking: Identify the location of the swarm in real-time Identify animals easily Increase efficiency and reduce human labor Secure your farm by using the tracker as an anti-theft device Weather change alerts Virtual fence to generate an alert when the animal leaves the designated […]

LoRaWAN IoT Button ships with open-source firmware, bootloader, and Android app

LoRaWAN is often used for asset tracking or environmental monitoring, for example, to track cattle location, or monitor temperature and humidity in a field, but n-Fuse’s “LoRaWAN IoT Action Button” enables human interaction and comes with open-source firmware, bootloader, and soon the source code for the Android app. Most of the n-Fuse STx-LR family of LoRaWAN nodes integrates environmental sensors but the LoRaWAN IoT Action Button is different with support supports single, double, and long presses, as well as tactile feedback. n-Fuse STx-LR family comes in three variants with the following key features: MCU – STMicro STM32L071KZU6 Arm Cortex-M0+ microcontroller @ 32 MHz with 192KB flash, 20KB RAM sta-lr – Action button with tactile feedback. stx-lr – TI HDC2080 environmental sensor (Temperature, Humidity), BMA400 motion sensor (acceleration), magnetic field sensitive Reed switch, ambient light sensor, and proximity sensor. ste-lr – Bosch BME680 environmental sensor with temperature, humidity, air pressure, and […]

SenseCAP T1000 – A credit card-sized LoRaWAN GPS tracker based on Semtech LR1110 (Crowdfunding)

SenseCAP T1000 is an ultra-thin credit-card-sized GPS tracker with Semtech LR1110 wireless chip with LoRaWAN, WiFi (scanning), and GNSS connectivity, plus two built-in sensors to monitor temperature, light intensity, and motion. We’ve covered several LTE IoT and LoRaWAN GPS trackers in the past and even tested the RAK811 LoRa GPS Tracker board with our own gateway, but the SenseCAP T1000 is particularly attractive due to its slim design. It works both indoors and outdoors with IP65 waterproof protection, looks quite easy to set up with its button and LED, and also integrates an SOS feature that can be triggered with a long press. SenseCAP T1000 specifications: Wireless Semtech LoRa Edge LR1110 Asset Management Platform LoRa/(G)FSK Half-Duplex RF transceiver working in the 150 – 960MHz; compatible with LoRaWAN 1.0.4 standard GNSS (GPS/ BeiDou) low-power scanning 802.11b/g/n Wi-Fi ultra-low-power passive scanning Unnamed Bluetooth 5.1 LE chip for initial configuration and indoor positioning […]

Setting up a private LoRaWAN network with WisGate Connect gateway

RAKwireless Wisgate Connect Gateway Review with Link.ONE devit

In this guide, we’ll explain how to set up a private LoRaWAN network using the Raspberry Pi CM4-based RAKwireless’ WisGate Connect gateway and Docker or Portainer to install NodeRED, InfluxDB, Grafana, and other packages required to configure our gateway. The WisGate Connect is quite a versatile gateway with Gigabit and 2.5Gbps Ethernet plus several optional wireless connectivity options such as LoRaWAN, 4G LTE, 5G, WiFi 6, Zigbee, WiFi HaLoW, and more that can be added through Mini PCIe or M.2 sockets, expansion through WisBlock IO connectors and a 40-pin Raspberry Pi HAT connector. We’ll start by looking at the gateway features in detail, but if you already know all that, you can jump to the private LoRaWAN network configuration section. WisGate Connect unboxing, specifications, and teardown RAKwireless sent us a model with a Raspberry Pi CM4 equipped with 4 GB of RAM and 32 GB of eMMC memory, GPS and […]
