Sony energy harvesting module generates power from electromagnetic wave noise

Sony Semiconductor Solutions Corporation (SSS) has developed an energy harvesting module that uses electromagnetic wave noise energy to power IoT devices. The new module leverages Sony’s tuner development process to generate power from electromagnetic wave noise from robots inside factories, monitors and lighting in offices, monitors and TVs in stores and homes, etc. in order to provide a stable power supply needed to run low-power IoT sensors and communications equipment. The tiny 7×7 mm module uses the metal parts of electronic devices that serve as the source of electromagnetic wave noise as part of an antenna and employs a rectifier circuit in order to convert electromagnetic wave noise in a range of several Hz to 100 MHz into electrical energy and supply power to low-power consumption IoT sensors and communications equipment or to charge batteries. The module harvests energy from electronic equipment that generates a significant amount of electromagnetic wave […]

ALFA Network HaLow-U – An 802.11ah WiFi HaLow USB adapter supporting AP and STA mode

ALFA Network HaLow-U is an 802.11ah WiFi HaLow USB adapter based on the Newracom NRC7292 chipset and NXP i.MX 6 processor that works both in access point (AP) and client (STA) modes. It delivers long-range WiFi up to one kilometer in the 900 MHz frequency ISM bands and is mostly useful for IP cameras and high-end sensors. The ecosystem around WiFi HaLow (802.11ah) is expanding slowly, but surely, and we previously covered a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras, and also ALFA Network’s AHPI7292S Raspberry Pi HAT that found its way into RAKWireless WisGate Connect gateway. The new HaLow-U USB adapter adds another way to bring WiFi HaLow connectivity to more devices. HaLow-U specifications: SoC – NXP i.MX6 Arm Cortex-A9 processor System Memory – 256MB DDR3 Storage – 32MB NOR flash Connectivity 802.11ah HaLow Newracom NRC7292 chipset […]
