SparkFun’s $125 “Indoor Air Quality Combo Sensor” combines the SCD41 and SEN55 environmental sensors

SparkFun Indoor Air Quality Sensor

SparkFun has released a new air quality multi-sensor board, the Indoor Air Quality Combo Sensor, which integrates the SCD41 and SEN55 sensors from Sensirion for measuring carbon dioxide, volatile organic compounds (VOCs), particulate matter, relative humidity, and temperature. The air quality multi-sensor board simplifies power management for the two sensors via onboard DC voltage conversion and allows a single Qwiic connection for power and communication. It features two Qwiic connectors and a 0.1”-space through-hole header for I2C and power. The board is not a complete solution for indoor air quality monitoring. It has to be connected to a Qwiic-enabled microcontroller such as SparkFun Thing Plus Matter, DataLogger IoT, and the ESP32 Qwiic Pro Mini. Users can install the required Arduino libraries — the Arduino Core library, Sensirion I2C SEN5x, and SparkFun SCD4x — either via the Arduino library manager or directly from SparkFun. The device is open-source, with hardware files, […]

The SenseCAP Watcher is a voice-controlled, physical AI agent for LLM-based space monitoring (Crowdfunding)

SenseCAP Watcher

Seeed Studio has launched a Kickstarter campaign for the SenseCAP Watcher, a physical AI agent capable of monitoring a space and taking actions based on events within that area. Described as the “world’s first Physical LLM Agent for Smarter Spaces,” the SenseCAP Watcher leverages onboard and cloud-based technologies to “bridge the gap between digital intelligence and physical applications.” The SenseCAP Watcher is powered by an ESP32-S3 microcontroller coupled with a Himax WiseEye2 HX6538 chip (Cortex-M55 and Ethos-U55 microNPU) for image and vector data processing. It builds on the Grove Vision AI V2 module and comes in a form factor about one-third the size of an iPhone. Onboard features include a camera, touchscreen, microphone, and speaker, supporting voice command recognition and multimodal sensor expansion. It runs the SenseCraft software suite which integrates on-device tinyML models with powerful large language models, either running on a remote cloud server or a local computer […]

Teledatics HaloMax Wi-Fi HaLow LGA or M.2 module supports over 1000 clients, have been tested at a 100+km range (Crowdfunding)

TD-WRLS development board

Teledatics has launched a crowdfunding campaign for the TD-HALOM HaloMax Wi-Fi HaLow module available in LGA and M.2 form factors for long-range and low-power connectivity, as well as HaLow development boards based on the module and various daughterboards for expansion. The wireless module, powered by Newracom’s NRC7394 SoC, is the product of a collaboration between Newracom and Teledatics. According to Zac Freeman, VP of Marketing & Sales at Newracom, the HaloMax module is “the highest output power Wi-Fi HaLow module available on the market. The Teledatics TD-HALOM module transmits at the highest allowable FCC power output and offers a Maximum Range HaLow solution.” Earlier this year, Teledatics broke the record for the longest distance for a Wi-Fi HaLow connection using the HaloMax wireless module and TE Connectivity Yagi antennas. Two Raspberry Pi 4 Model B units were able to communicate over a distance of 106km between Mount Greylock and Mount […]

DeepRad is a cheap, modular SDR receiver based on the RTL-SDR (Crowdfunding)

Deeprad Single modular SDR receiver

DeepRad is a software-defined radio (SDR) receiver built in the RTL-SDR form factor. The modular SDR receiver offers advantages over other RTL-SDR-based devices which make it easier to integrate with other components and build custom solutions for your specific applications. The DeepRad SDR receiver is based on the RTL-SDR dongle and features the same Realtek RTL2832U demodulator chip with an R860T tuner. The module features D+ and D- pins for USB connection, V+ for 5 V power supply, solderable jumpers for oscillator selection, an RF pin for antenna connection, and 8 shield pin connectors for shielding and support. The module is targeted at custom designs, with the user free to choose the best components for their application.
