Engineer and YouTuber Carl Bugeja recently developed CodeCell, a tiny ESP32-C3 development board designed as the brain for robots, wearables, and smart home devices. This module features a nine-axis inertial measurement unit (IMU) for motion fusion and an optional VCNL4040 light sensor. It includes a USB Type-C port for data and power as well as a lithium-polymer battery with a charging circuit. Measuring just 18.5 x 18.5mm this compact board is even smaller than other tiny ESP32 development boards such as Waveshare’s ESP32-S3-Zero and Seeed Studio’s XIAO ESP32S3. However, the Epi C3 is smaller at 23 x 12.75 mm, and so are the Unexpected Maker NANOS3 (25 x 10 mm) and Unexpected Maker OMGS3 (28 x 11 mm).

SparkFun’s $125 “Indoor Air Quality Combo Sensor” combines the SCD41 and SEN55 environmental sensors
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, […]
STMicro VL53L9 is a high-resolution, direct Time-of-Flight 3D LiDAR sensor module
The STMicro VL53L9 sensor is the latest addition to the company’s FlightSense product family. The direct Time-of-Flight (ToF) 3D LIDAR (light detection and ranging) sensor offers a resolution of up to 2,300 zones. The module is described as all-in-one and easy to integrate. It comes in a small, reflowable package that contains all the necessary components for sensing objects and processing images. The sensor features an array of single photon avalanche diodes (SPADs) for photon detection, a post-processing SoC, and two vertical surface emitting lasers (VCSELs) powered by a dedicated bipolar-CMOS-DMOS (BCD) VCSEL. The VL53L9 is a multi-zone ToF sensor similar to the VL53L7CX and the VL53L8, meaning that it offers multi-zone distance measurements up to 54 x 42 zones with a wide 54° x 42° field-of-view. Unlike most IR sensors, the VL53L9 sensor uses backside illumination direct ToF technology to ensure absolute distance measurement, regardless of the target color […]
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 […]
RAKwireless adds more Wisduo and Wisblock modules, launches WisToolBox configuration tool for IoT devices

Dragino LDS02 LoRaWAN door and window sensor offers long range and battery life
Home automation usually relies on short-range wireless standards such as Bluetooth LE, Zigbee, or WiFi, sometimes with the help of repeaters for larger houses. But if you need to monitor large houses, several houses on a piece of land, or apartments, you’d be glad that you can also do so, at least for doors and windows, with LoRaWAN using Dragino LDS02 sensor. The LDS02 sensor will work like your typical wireless door/window sensor, detection when those are opened and closed, and for how long, but will offer a much longer range of up to 2km in urban settings, as well as battery life meaning it could last for years depending on the frequency of door/window events, as well as uplink frequency configuration. Dragino LDS02 LoRaWAN door sensor specifications: Based on SX1262 LoRa transceiver LoRaWAN v1.0.3 Class A Bands – CN470, EU433, KR920, US915, EU868, AS923, AU915, IN865 Door Open/Close detection […]
IoT device monitoring as a product reliability improvement tool
CNXSoft: This is a guest post by Renato Kiss, Product Manager – Software at Toradex, explaining how IoT device monitoring can be used with open-source software tools like Fluent Bit to improve product reliability, using temperature monitoring as an example. It is impossible to dissociate connected devices from modern life. They are present in homes, offices, industries – basically, in every business, connected devices play vital roles. In a market estimated at 24.1 billion devices and with a revenue of more than USD 1.5 trillion by 2030, IoT will grow based on both consumer and business applications. Hardware will account for about one-third of this value with the majority being distributed in services, including the connectivity for the system. As part of this growth, more services will be added to IoT business and some specialists estimate the economic potential, including IoT products and services, can unlock at least USD 5.5 […]
