This series marks a significant advancement in the field of industrial sensing applications, offering long-range data transmission combined with power efficiency. The EVA-2000 series, comprising of diverse sensor models from temperature and humidity to water leak detection, is designed for the demanding sectors of industrial automation, equipment monitoring, and environmental monitoring.

At the heart of the EVA-2000 series’ functionality lies their ability to efficiently gather and transmit data wirelessly over extended distances through low-power, wide area LoRaWAN technology. This capability is further enhanced by their low power consumption, attributed to their double 3.6v Li-ion batteries, ensuring prolonged battery life. The adherence to LoRaWAN standards not only promises scalability and cost-effectiveness in the deployment of a multitude of devices but also simplifies integration within existing systems. Moreover, each unit in the series uses a built-in embedded antenna in a compact design that facilitates flexible installation across varied environments.

Standout products in this series include the EVA-2210, which is a 3-phase current meter equipped with 3 x 75A clamp-on CT. EVA-2210 is adept at measuring equipment currents up to 75A in diverse applications such as pumps, fan motors, compressors, computers, and servers. Eliminating the need for complex wiring, the EVA-2210 significantly enhances energy management efficiency for distributed devices.

Further enhancing the versatility of the series are the EVA-2310 and EVA-2311 models. The EVA-2310 is a temperature and humidity sensor for monitoring environments in offices, hospitals, classrooms, and warehouses.

The EVA-2311 uses a PT1000 round head heat probe sensor, which extends its utility with a 2m length cable and IP67 rating, making it suitable for extreme temperature detection ranging from -70°C to 200°C.

The EVA-2510 model is a water leakage sensor, which serves as a sensor for use in cooling and water treatment systems, detecting and alerting operators to potential issues before they happen. Such models are indispensable for industrial processes that rely on precise environmental parameter measurements.

All the EVA-2000 series products are seamlessly compatible with the Advantech WISE-6610, industrial LoRaWAN gateway, allowing for easy remote creation, synchronisation of channel settings, and data rate adjustments. Once connected, application settings such as data update cycles and thresholds can be configured via downlink commands from WISE-6610, further streamlining the monitoring and management process.

Insight SiP launches miniature Wi-Fi 6 combo module with integrated antennas

Insight SiP has launched its ISP5261 Wi-Fi 6 module at Embedded World 2024. This module acts as a fully functioning Bluetooth LE and Wi-Fi radio node, capable of a long autonomous operation on battery power. It can form the core of an autonomous IOT device requiring Bluetooth LE and Wi-Fi connectivity.

This device offers integration and miniaturisation of RF technologies, using System in Package technology. The device also benefits from Insight SiP’s proprietary “Antenna-in-Package” techniques.

The module is based on NXP Semiconductors RW612 single-chip Wi-Fi/Bluetooth LE/802.15.4 Wireless MCU System on Chip (SoC). The module integrates a 32-bit ARM Cortex-M33 CPU running at 260 MHz, additional 4 MB of QSPI flash memory, 1.2 MB SRAM as well as analog and digital peripherals. Its powerful processor and ample memory permit this module to be used as the core of a sophisticated IOT application.

Despite the small size of 12 x 12 x 1.8 mm, the module integrates decoupling capacitors, 40 MHz crystal for Wi-Fi and Bluetooth LE and 32.768 kHz crystal for low power timing, DC-DC converters, RF matching circuits and a dual-band (2.4 and 5 GHz) antenna. This module thus offers class leading performance and miniaturisation.

Low power consumption and advanced power management enable battery lifetimes up to several months on AA batteries. Wi-Fi communication is compliant with the Wi-Fi Alliance specifications for Wi-Fi 6 including the following protocols: IEEE 802.11ax/ac/n/a/g/b/e/i/k/v/w.

Bluetooth LE connectivity is compliant with Bluetooth 5.4, enabling Long Range communication. ISP5261 Bluetooth LE section can be used either in peripheral or central roles and can handle up to 16 simultaneous central/peripheral connections. Also supported are the Matter and Thread protocols, allowing easy internet access and support for SmartHome applications.

Security Features are prominent in the module, with an ARM TrustZone processor, and NXP Edgelock hardware security module, supporting Root of Trust, secure communication and update verification.

Rohm develops a new Op Amp that minimises current consumption

Rohm has developed a linear operational amplifier (op amp) – LMR1901YG-M – featuring the lowest* current consumption in the industry. This makes it ideal for amplifying sensor signals used to detect and measure temperature, flow rate, gas concentration, and other parameters in applications powered by internal sources (i.e. batteries).

In recent years, advanced control has been in increasing demand for various applications in consumer and industrial electronics. Therefore, there is an increasing need for accurate sensing of parameters relevant to the application – such as, temperature, humidity, vibration, pressure, and flow rate. Op amps whose main function is to amplify sensor signals for subsequent detection and/or analog-to-digital conversion, is a crucial component in the signal chain – greatly affecting both accuracy and power consumption. Rohm is developing op amps that satisfy the dual need for high accuracy and low current consumption. By further refining the circuit design based on original Nano Energy technology.

The LMR1901YG-M leverages original ultra-low power technology that thoroughly suppresses current increase caused by temperature and voltage changes to reduce current consumption to just 160nA (Typ.) – approximately 38% lower than that of general low power op amps. This not only extends the life of applications powered by internal batteries like electronic shelf labels, but also contributes to longer operating times for smartphones and other devices equipped with rechargeable batteries. At the same time, this low current consumption does not change over the temperature range of -40°C to +105°C – allowing stable low-power operation, even in environments where external temperatures fluctuate, including fire alarms and environmental sensors.

Other performance enhancements include 45% reduction of input offset voltage to just 0.55mV (Max. Ta=25°C) over general low-current op amps while a maximum input offset voltage temperature drift of 7V/°C is guaranteed. This enables high accuracy amplification of sensor signals. Capable of operating from 1.7V to 5.5V supply voltage and offering rail-to-rail input/output, LMR1901YG-M is suitable for a wide variety of applications in the industrial equipment and consumer markets. Rohm’s new op amp also complies with the automotive reliability standard AEC-Q100 – ensuring stable operation even under harsh conditions such as vehicle cabins without compromising functionality.

In addition to various technical documents necessary for circuit design and SPICE models for simulation (available free of charge on Rohm’s website), the LMR1901YG-M can be used with Rohm Solution Simulator to speed up time to market.
