AI, computer vision meet LoRaWAN with SenseCAP K1100 sensor prototype kit

Wio Terminal Grove Vision AI LoRaWAN module

CNXSoft: This is another tutorial using SenseCAP K1100 sensor prototype kit translated from CNX Software Thai. This post shows how computer vision/AI vision can be combined with LoRaWAN using the Arduino-programmable Wio Terminal, a Grove camera module, and LoRa-E5 module connecting to a private LoRaWAN network using open-source tools such as Node-RED and InfluxDB. In the first part of SenseCAP K1100 review/tutorial we connected various sensors to the Wio Terminal board and transmitted the data wirelessly through the LoRa-E5 LoRaWAN module after setting the frequency band for Thailand (AS923). In the second part, we’ll connect the Grove Vision AI module part of the SenseCAP K1100 sensor prototype kit to the Wio Terminal in order to train models to capture faces and display the results from the camera on the computer. and evaluate the results of how accurate the Face detection Model is. Finally, we’ll send the data (e.g. confidence) using […]

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

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 […]

Elecrow’s Raspberry Pi Pico Advanced Kit ships with 32 electronics modules, 32 project tutorials

We’ve just reviewed the Raspberry Pi 4-powered CrowPi L laptop and Crowtail Starter kit used to teach programming and electronics, but Elecrow has now launched the “Raspberry Pi Pico Advanced Kit” with 32 electronics modules, a smart kit car, and 32 tutorials that should be a more affordable way of teaching electronics and programming. However, it does so in a different way, as instead of using visual programming and Python, the Raspberry Pi Pico Advanced Kit’s lessons rely on MicroPython, and the projects are different with for example parts to build an obstacle avoidance, line tracking, or remote controlled car. Package content: Optional Raspberry Pi Pico board with Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller Breadboards 2x 400 holes solderless breadboards 1x 170 holes solderless breadboard Display modules 1602 LCD display module (Blue) OLED module 4-bit digital LED display module Lights 10x 5mm LEDs in green, red, blue, yellow, and […]

Nordic Semi nRF7002 is a dual-band WiFi 6 companion IC for nRF52, nRF53, and nRF91 wireless chips

Nordic Semiconductor nRF7002 dual-band WiFi 6 companion chip is the first WiFi chip from the company and is designed to add Wi-Fi connectivity to solutions based on nRF52840 and nRF5340 wireless SoCs, and nRF9160 cellular IoT SiP, as well as non-Nordic host microcontrollers. The nRF7002 also adds Wi-Fi-based locationing (SSID sniffing of local Wi-Fi hubs) when used alongside Nordic’s existing products, and the launch means Nordic is now one of the rare companies offering chips for Bluetooth, 802.15.4 (Matter/Thread), Wi-Fi, and cellular IoT (NB-IoT, LTE Cat M). This was made possible with the acquisition of the development team, core Wi-Fi expertise, and Wi-Fi IP assets of Imagination Technologies Group in 2020. Nordic Semi nRF7002 key features specifications: Complies with 802.11a/b/g/n/ac/ax 2.4 GHz and 5 GHz dual-band Wi-Fi 6 Station (STA) 1 Spatial Stream (SS) 20 MHz channel bandwidth 64 QAM (MCS7), 86 Mbps PHY throughput OFDMA (Downlink and Uplink) BSS […]

AquaPing is an open-source, battery powered acoustic water leak detector module (Crowdfunding)

The AquaPing is an open-source hardware, ultra-low power acoustic water leak detector sensor based on Texas Instruments MSP430 microcontroller and a microphone that can detect leaks without having to do any plumbing, instead capturing audio for water leak detection, and it even works for leaks behind walls. All signal processing and analysis occur on the MSP430 MCU, so no audio is streamed to the cloud and eavesdropping is impossible, plus the sensor only captures high frequencies out of the range of normal conversations, so eavesdropping is not feasible, plus those higher frequencies are also said to provide highest sensitivity and reliability. AquaPing specifications: MCU – Texas Instruments MSP430FR5994 microcontroller to perform FFT spectral analysis (10x faster/efficient than ARM-Cortex M0+) Audio capture – MEMS microphone covered by a small rectangular plastic structure to form a Helmholtz resonator. Minimum detectable leak rate – 0.01 gpm (gallon per minute) depending on stand-off distance […]
