Sparkfun’s Pulsed Coherent Radar Sensor features Acconeer XM125 60 GHz module, works through walls, offers up to 20-meter range

SparkFun Pulsed Coherent Radar Sensor Acconeer XM125 Qwiic

SparkFun has launched a new Qwiic breakout board for the Acconeer XM125 60 GHz pulsed coherent radar sensor that can measure distance to humans even through walls and works at a distance of up to 20 meters. We’ve seen tiny 24GHz or 60GHz radar modules for several years now, and Supachai even reviewed the Seeed Studio mmWave sensor using ESPHome and Home Assistant late last year with the solution relying on Frequency-Modulated Continuous Wave (FMCW) technology. The Acconneer XM125 is a Pulse-radar module that emits electromagnetic waves in short bursts instead of continuously like FMCW radars and allows longer measurement ranges potentially at the cost of lower accuracy. Sparkfun Pulse Coherent Radar Sensor specifications: Acconeer XM125 Module A121  60GHz Pulsed Coherent Radar (PCR) Integrated baseband, RF front-end, and antenna in package Detects distance, speed, motion, and objects up to 20 meters away Millimeter precise readings Low power consumption STMicro STM32L431CBY6 […]

The Lark Weather Station works with Arduino, ESP32, micro:bit, Raspberry Pi, and other boards

Lark Weather Station Arduino ESP32 Raspberry Pi

The Lark Weather Station measures wind speed, wind direction, temperature, humidity, and air pressure through a range of sensors and connects to popular development boards such as Arduino UNO, ESP32, BBC micro:bit, Raspberry Pi, or DFRobot Unihiker through I2C or UART. We’ve seen several projects for Internet-connection weather stations that retrieve weather data from the web and display the results locally, but the Lark Weather Station allows the users to get atmospheric data right in his/her current location thanks to its built-in anemometer, wind vane, and built-in sensors, as well as expansion interfaces for additional sensors. Lark Weather Station specifications: Storage – 16MB flash good to store about 160 days of data (when data is recorded once per minute) Sensors Compass Anemometer Wind Speed: 0.5~12m/s Cover to protect the anemometer during storage/transport Wind vane and wind direction shaft to report the wind direction (eight directions) Temperature Range –20~60℃ ±0.2℃ Humidity […]

Arduino Nano 33 BLE Rev2 board features BMI270 six-axis IMU and BMM150 magnetometer

Arduino Nano 33 BLE Rev2

Arduino Nano 33 BLE Rev2 is an update to the Arduino Nano 33 BLE board launched in 2019 that features two IMU sensors instead of one with the BMI270 6-axis accelerometer and gyroscope and the BMM150 3-axis magnetometer and also comes with a few changes made after feedback from users. The new board is still powered by an nRF52840 Bluetooth LE module (u-Blox NINA B306) and remains Arduino Nano compatibility with two rows of 15-pin headers, but replaces the 9-axis IMU with the BMI270 and BMM150 chips, adds new pads and test points for USB, SWDIO, and SWCLK, a new VUSB soldering jumper, and brings changes to the power circuitry. Arduino Nano 33 BLE Rev2 specifications: Wireless Module – U-blox NINA B306 module SoC – Nordic Semi nRF52840 MCU Core – Arm Cortex-M4F microcontroller @ 64MHz Memory and storage – 1MB Flash, 256KB RAM Bluetooth 5.0 LE Up to 2 […]

$166 Mustool MT13S thermal imager doubles as multimeter

Mustool MT13S 2-In-1 Thermal Imager Multimeter

Mustool MT13S is a relatively inexpensive 2-in-1 thermal imager and multimeter with a 2.8-inch touchscreen display and an IR camera with a 192×192 resolution. Thermal cameras used to be quite expensive, but in recent years, we’ve seen cheaper models such as the HT-102 thermal camera for Android smartphones and M5Stack T-Lite Wi-Fi thermal camera, but those integrate fairly small 32×32 and 32×24 pixels IR arrays, The Mustool MT13S provides a higher resolution 192×192 thermal camera and doubles as a 10,000-count multimeter for about $166 plus shipping on Banggood or around $177 including shipping on Aliexpress. Mustool MT13S specifications: Thermal imaging Sensor – Uncooled focal plane Image capture frequency – 20Hz Thermal imaging resolution – 192 x 192 Display image resolution – 240 x 240 Field of view (FoV) – 50.0(H) × 50(V)/72.1(D) Emissivity – 0.1-0.99 is tunable and 0.95 is the default Temperature Range – -20°C to +550°C Accuracy – […]

Doly – A cute little autonomous AI-powered robot based on Raspberry Pi CM4 module (Crowdfunding)

Doly Raspberry Pi CM4 robot

Limitbit Doly is a cute little autonomous robot with two continuous tracks, two small arms controlled by servos, two round color displays acting as the eyes, and various sensors, all controlled by a Raspberry Pi CM4 system-on-module.
