NOVELDA’s latest UWB radar presence sensor consumes less than 100 µW

NOVELDA UWB presence sensor

NOVELDA has unveiled a new low-power ultra-wideband (UWB) radar presence sensor with a power consumption of under 100 µW and designed to operate on two AAA batteries for up to four years. We first wrote about NOVELDA in 2021 where we covered their UWB X4 presence sensor capable of detecting submillimeter movements with a power consumption of under 2mW. The company has further optimized the technology and has come up with a 30x5mm module capable of doing the same with 0.1mW power consumption. The sensor is said to work behind various materials such as plastics, tempered glass, and ceramics, the detection zone size and shape can be adjusted to meet the application requirements, and the device provides accurate angle and distance information. The new ultra-low power UWB radar presence sensor will mostly be useful for energy/resource savings, lengthening a product’s life cycle, and health monitoring with some of the potential […]

Challenger RP2040 board gets DWM3000 UWB module for indoor positioning, up to 10 Mbps data transfers

Challenger RP2040 UWB

The Challenger RP2040 UWB board features a Raspberry Pi RP2040 microcontroller combined with a DWM300 UWB (Ultra-Wide Band) module in the Adafruit Feather form factor and is designed for indoor positioning and ranging applications with an up to 10-centimeter accuracy, and data transfers up to 10 Mbps. The first Challenger RP2040 board was introduced in 2021 with an ESP8285 WiFi chip, iLabs (Invector Labs) shortly followed up with the Challenger RP2040 LoRa with an RFM95W LoRa module, and they also made models with NFC and cellular connectivity. The Swedish company has now just introduced their latest Challenger board with the Challenger RP2040 UWB leveraging UWB technology. Challenger RP2040 LoRa board preliminary specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Wireless module – Qorvo DWM3000 UWB module connected via SPI Chip – Qorvo DW3110 ultra-wideband (UWB) transceiver IC, compliant with IEEE […]

The Wi-R protocol relies on body for data communication, consumes up to 100x less than Bluetooth

Wi-R vs Bluetooth

The Wi-R protocol is a non-radiative near-field communication technology that uses Electro-Quasistatic (EQS) fields for communication enabling the body to be used as a conductor and that consumes up to 100x less energy per bit compared to Bluetooth. In a sense, Wi-R combines wireless and wired communication. Wi-R itself only has a wireless range of 5 to 10cm, but since it also uses the body to which the Wi-R device is attached, the range on the conductor is up to 5 meters. While traditional wireless solutions like Bluetooth create a 5 to 10-meter field around a person, the Wi-R protocol creates a body area network (BAN) that could be used to connect a smartphone to a pacemaker, smartwatch, and/or headphones with higher security/privacy and longer battery life.   One of the first Wi-R chips is Ixana YR11 with up to 1Mbps data rate, and they are working on a YR21 […]

Year 2021 in review – Top 10 posts and statistics

cnx software happy new year 2022

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and  Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

Indoor positioning BU01 development board can detect tiny body movements (Sponsored)

Ai Thinker BU01 development board

GPS is available for outdoor positioning, what about indoors? There is a positioning technology that is more accurate than GPS: UWB. The technology offers positioning accuracy within 10cm which greatly compensates for the shortcomings of the indoor RSSI positioning of past IoT products. UWB technology is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz. It does not use a sinusoidal carrier but uses nanosecond-level non-sinusoidal narrow pulses to transmit data and occupies a large frequency spectrum, hence the name “Ultra-Wideband”, or UWB for shorts. Besides positioning, UWB can also be used for data transmission with a rate of hundreds of megabits per second. BU01 development board features MCU – STMicro STM32F103 Arm Cortex-M3 microcontroller UWB module – Ai-Thinker BU01 module 50 I/O pins exposed for functions. Sensors – Onboard acceleration sensor, temperature, and humidity sensor Misc – User buttons and LED Power Supply – 5V […]

NOVELDA UWB X4 sensor can detect submillimeter movements

NOVELDA UWB X4F103 sensor

We’ve just written about an ESP32 UWB board equipped with an ultra-wideband module designed for indoor positioning with about 10 centimeters accuracy, which should be good enough for many applications, but it turns out UWB sensors can be made to be much more accurate. NOVELDA has just announced the UWB X4/X4F103 sensor and development kit that can detect submillimeter micro-movements such as breathing for human presence detection and does so at a really low power consumption of under 2mW. NOVELDA UWB X4 (X4F103) highlights: High-precision ranging for accurate distance measurement and absolute range bounding based on patented impulse radar technology Low power consumption below 2mW, and no co-existence issues with other sensors Wide detection zone for accurate detection with up to 180-degree field of view Up to 5m range Works through plastic and glass or layers of clothing Package – 12 x 12mm sensor A big difference compares to Decawave […]

ESP32 UWB board features DW1000 module for accurate indoor positioning

ESP32 UWB board

FiRa “Fine Ranging” UWB technology was introduced a few years ago and is now found in devkits and Apple U1 chip. Makerfabs ESP32 UWB board provides another option with Espressif ESP32-WROVER-32 or ESP32-WROOM-32 WiFi & Bluetooth module combined with a Decawave DW1000 module for precision tracking. Makerfabs explains the board acts like a continuously scanning radar that locks onto another device (called Anchor, since it’s usually in a fixed location) and communicates with it to determine the distance between objects by calculating the time of flight (ToF) between devices, or in other words, the roundtrip time of challenge/response packets. ESP32 UWB board specifications: Wireless modules: WiFi & Bluetooth LE – ESP32-WROVER-32 or ESP32-WROOM-32 module with ESP32 dual-core processor @ 240 MHz UWB – B&T BU01 module based on Decawave DW1000 chip; IEEE802.15.4-2011 UWB compliant wireless transceiver module with a precision of 10cm indoors, a data rate of up to 6.8 […]
