Indoor air quality sensors are based on LoRaWAN

Indoor air and environment quality sensors developed by IQnexus use Semtech’s LoRa devices that run via the LoRaWAN standard for building automation.

According to IQnexus, the IAQ sensors comply to three key benchmarks for building owners, namely no ongoing cloud fees, reduce carbon dioxide emissions and are compliant with the WELL and RESET standards. The LoRa and LoRaWAN sensors are easy to deploy and are cost-effective for seamless integration into existing building infrastructures.

When developing the IAQ sensors, IQnexus wanted to take a completely different approach to how IoT can improve a building’s air quality. “For an easy, on-premise solution we chose to implement Semtech’s LoRa devices and the LoRaWAN standard into the indoor sensor for building owners to accurately monitor their building’s indoor air quality all in real time,” explained Michael Welzel, chief technology officer, IQnexus.

Through the use and connectivity of LoRaWAN, the IAQ sensor is able to communicate through standard protocols like BACnet and ModBus to any building automation/energy management system, and even supervisory control and data acquisition (SCADA) systems.

According to IQnexus, a typical installation of the IAQ sensors features one IoT platform, installed on an on-premise NBNANOs server, about 20 to 30 gateways, and 700 to 1000 sensors for a 30 to 50 floor building. The sensors cover IAQ and IEQ, as well as provide a higher comfort by measuring single HVAC zones.

Semtech’s LoRa device-to-cloud platform is a globally adopted long range, low power solution for IoT applications, enabling the rapid development and deployment of ultra-low power, cost efficient and long range IoT networks, gateways, sensors, module products, and IoT services worldwide. Semtech’s LoRa devices provide the communication layer for the LoRaWAN standard, which is maintained by the LoRa Alliance, an open IoT alliance for low power wide area network (LPWAN) applications that has been used to deploy IoT networks in over 100 countries. Semtech is a founding member of the LoRa Alliance.

IQnexus was launched in 2016 with the purpose of bringing the Internet of Things to New Zealand. Successful deployment of sensors in a variety of sectors have enabled IQnexus to position itself as the go-to place for hardware, sensor developments and IoT integrations. From smart agricultural to smart energy management systems, IQnexus plans to lead the way in the technology sector with developments that bring efficiencies to buildings, production and manufacturing processes, making better use of resources and in turn making the world a greener place to live.

Chip scale atomic clock (CSAC) is designed for mission-critical military projects

Precise timing is required for advanced military platforms, ocean-bottom survey systems and remote sensing applications, says Microchip, as it introduces the SA65 chip scale atomic clock (CSAC).

The CSACs are used to ensure stable and accurate timing even when global navigation satellite systems (GNSS) time signals are unavailable. Microchip’s SA65 CSAC is environmentally rugged and has double the frequency stability over a wider area of the earlier SA.45s CSAC. It also has faster warm up at cold temperatures. The SA65 has an operating temperature range of -40 to 80 degrees C and a storage temperature range of -55 to 105 degrees C. The warm-up time of two minutes at -40 degrees C is 33 per cent faster than that of the SA.45s.

The SA65 CSAC is intended to be portable for military applications such as assured position, navigation and timing (A-PNT) and command, control, communications, computers, cyber, intelligence, surveillance and reconnaissance (C5ISR), which require precise frequencies generated by a low size, weight and power (SWaP) atomic clock.

The CSAC also has improvements such as fast warm-up to frequency after cold start, temperature stability over a wide operating range, and frequency accuracy and stability, all of which extend operation while GNSS is denied help, says Microchip.

Claimed to be the world’s lowest-power commercial atomic clock, the CSAC provides precise timing for portable and battery-powered applications requiring continuous operation and holdover in GNSS-denied environments. The SA65 is form-, fit- and function-compatible with the SA.45s, which minimises risk and redesign costs when upgrading to improve performance and environmental insensitivity.

The CSAC family of atomic clocks is supported by Developer Kit 990-00123-000, as well as associated software, a user guide and technical support.

Microchip Technology provides smart, connected and secure embedded control solutions and development tools. The company’s solutions serve more than 120,000 customers across the industrial, automotive, consumer, aerospace and defence, communications and computing markets. It is headquartered in Chandler, Arizona, USA.

Farnell extends Nordic Semiconductor offering with its first PMIC

The first power management IC (PMIC) from Nordic Semiconductor, the nPM1100, is now available from Farnell. Claimed to be the industry’s most compact PMIC, it is intended for wearable electronics, remote controls, personal medical devices and smart home sensors.

The nPM1100 can be used as a generic PMIC for any application using rechargeable Li-ion/Li-Po batteries, advised Farnell. PCB space requirements are as low as 23mm², makes it particularly well suited to be integrated into wearables, connected medical devices and projects which have limited space. No configuration software is required to operate as all settings are pin-configurable. It can be used to conserve energy in designs, and can charge small batteries while providing efficient power management in

The nPM1100-CAAA is a small form factor dedicated PMIC with a dual-mode configurable buck regulator and integrated battery charger. It is a complementary component to Nordic’s SoCs and also has over-voltage protection, low current mode and an operating range of -40 to +85 degrees C.

Farnell also offers the nPM1100 evaluation kit which does not require software to operate and is performance optimised for the PMIC with electrical connectors and physical interfaces for operation. It features switches for all selectable settings, buttons to enter and exit ship mode and connectors for batteries, USB and headers for all pins on the PMIC. The kit may be used with other development kits such as Nordic’s nRF5340-DK or it can be used to test the PMIC’s functionality with non-Nordic products. The kit also includes indicator LEDs for charge and error indication.

Nordic Semiconductor specialises in low power wireless technology with Bluetooth Low Energy solutions, complemented by ANT+, Bluetooth mesh, Thread, and Zigbee products.

Lee Turner, global head of semiconductors and single board computing at Farnell said: “We are pleased to expand our PMIC range with the latest products from Nordic Semiconductor. The . . .  nPM1100 is an ideal solution to help our customers reduce energy consumption in their designs. The ability to charge small batteries and extend battery life while providing efficient power management within small, space constrained applications, such as wearables and connected medical devices, is now of critical importance.”
