This GitHub repository contains the development of an APRS hub that transmits various sensor data like spO2, location, and altitude. The project uses Raspberry Pi, Tiny Circuit Python boards, and MQTT for data transmission.
A new smartphone app called VibMilk uses a phone's vibration motor to detect if milk is spoiled without opening the carton.
A technique called lock-in thermography can enhance the thermal resolution of even low-cost IR cameras, allowing for more detailed thermal imaging by periodically modulating the heat produced by a device and applying math to the captured images.
The IoT-LLM framework improves Large Language Models' (LLMs) task reasoning capabilities in real-world IoT systems through a three-step process that preprocesses IoT sensor data, activates commonsense knowledge, and enhances retrieval-augmented generation, achieving significant performance improvements in real-world tasks such as heartbeat anomaly detection.
Seeed Studio has introduced two new mmWave sensor kits, designed for edge AI detection of falls and heartbeats respectively. These kits are powered by the company's XIAO ESP32C6 development board and pre-installed edge-AI algorithms.
rtl_433 is an open-source program designed to decode radio transmissions from various devices operating on ISM bands. It supports RTL-SDR and SoapySDR and can decode a wide range of sensors, including temperature, humidity, and rain gauges. The software is written in C and is known for its low resource consumption.
The AI Camera is a portable, low-power device that combines a Raspberry Pi Zero, a 2MP camera module, and a range of sensors, designed for capturing and processing images locally with AI capabilities.
Autonomous tech developer Mobileye is ending in-house lidar development, citing the decreasing cost of off-the-shelf lidar and prioritizing imaging radar and vision-based sensors.
"Lidar is still seen as a crucial technology for SAE Level 3 cars and SAE Level 4 robotaxis alike, but this doesn't mean it makes sense for all autonomous tech developers to focus most of their time on sensor hardware."
