The Energy Harvesting with Wireless Sensor Node Reference Design illustrates how to use an Si1xxx wireless microcontroller in an extremely low power wireless sensor application.

The wireless sensor node is powered by a solar cell array. The power that is produced by solar energy is stored in a thin film battery. The wireless microcontroller measures temperature, charge level on the thin battery and light level. This data is then sent wirelessly to a USB adapter that is connected to a PC.

The PC runs a GUI that displays the information graphically.

The Energy Harvesting Reference Design includes software that is loaded on PC to display the quantities that are measured by the MCU in the wireless sensor node including: temperature, light level and charge level.

Teams with industry-leading suppliers to provide comprehensive, self-sustaining, ultra-low-power wireless sensor network solution

June 16, 2011 10:24 AM Eastern Daylight Time 

MELVILLE, N.Y.–(EON: Enhanced Online News)–Arrow Electronics, Inc. has joined with leading suppliers Silicon Labs, Infinite Power Solutions and Linear Technology Corporation to launch a turnkey energy-harvesting reference design enabling wireless networks powered by a solar energy-harvesting source.

“Working together with industry leaders Silicon Labs, Infinite Power Solutions and Linear Technology, we’ve developed a complete solution that can help customers reduce the complexity and enhance the sustainability of a variety of wireless networking applications”

The energy-harvesting reference design offers a simple, cost-effective bill of materials based on several key components. The design includes a solar-powered wireless sensor node that measures temperature, light level and charge level. It uses Silicon Labs’ ultra-low-power Si10xx wireless microcontroller (MCU) to control the sensor system and transmit data wirelessly. It also incorporates a thin-film battery to store harvested energy, as well as a battery charger IC for efficient power management. The data is transmitted to a wireless USB adapter included with the reference design that connects the wireless sensor node to a PC where sensor data for up to four nodes is displayed via an easy-to-use network GUI.

“Working together with industry leaders Silicon Labs, Infinite Power Solutions and Linear Technology, we’ve developed a complete solution that can help customers reduce the complexity and enhance the sustainability of a variety of wireless networking applications,” said David West, vice president of supplier marketing and asset for Arrow Electronics.

Silicon Labs’ Si10xx wireless MCUs offer very low active current of 160 µA/MHz and very low sleep mode current, as low as 25 nA, to conserve system resources. The Si10xx MCUs can also wake up very quickly in 2 µS. An on-chip wireless transceiver enables 20 dBm output power and RF sensitivity of -121 dBm, greatly increasing the wireless range. An integrated dc-dc switching regulator enables a wide input voltage range of 0.9V to 3.6V, which is particularly useful in energy-harvesting applications where outputs typically vary.

The reference design uses a THINERGY® solid-state, rechargeable, micro-energy cell (MEC), a unique type of thin film battery, with a capacity of 0.7 mAh developed by Infinite Power Solutions. In direct sunlight, the battery can be recharged fully in only one hour. While in sleep mode, the wireless sensor node will retain a charge for 7,000 hours. If the wireless system is transmitting continuously, it will operate non-stop for about three hours, although it is designed to constantly recharge itself at an appropriate level to keep the MEC from completely discharging.

Linear’s LTC4071 battery charger IC provides additional power management and offers an easy-to-use shunt battery system for Li-ion/Polymer batteries that integrates a charger and battery pack protection into one IC.

The LTC4071, with its 550 nA operating current, charges and protects batteries from previously unusable very low current, intermittent or continuous charging sources.

The LTC4071 can charge at currents up to 50 mA. A near zero (0.1 nA ) low-battery-latching disconnect function protects even low-capacity batteries from deep discharge and potentially irreparable damage. With pin-selectable settings of 4.0 V, 4.1 V or 4.2V, the LTC4071 IC’s 1 percent accurate battery float voltage allows the developer to optimize the balance between battery capacity and lifetime.

Silicon Labs’ wireless sensor energy-harvesting reference design accommodates a wide range of harvested energy sources. An on-board bypass connector gives developers the flexibility to tap other energy-harvesting sources such as vibration, thermal and RF.

Silicon Labs buys Irish sensor startup

Peter Clarke

10/12/2010 7:56 AM EDT

LONDON – Silicon Laboratories Inc. has acquired ChipSensors Ltd., a developer of a dielectric-as-sensor technology designed to detect temperature, humidity and gases. The amount paid was not disclosed.
Fabless chip company ChipSensors (Limerick Ireland), formed in 2006, has been developing a technology that allows the surface of an IC to be used to sense temperature, humidity, certain gases and pathogens. The technology makes use of the low-k dielectric material used in standard sub-micron CMOS process technology as an insulator between metal interconnect. That material is porous, and by selectively admitting or blocking ingress of the agent to be sensed, the dielectric constant of the material can be changed, forming a capacitive sensor.
Normally the surface of an IC is passivated to prevent ambient conditions affecting it. Similarly the pores of low-k material are often surface treated. However ChipSensors indicated that by letting ambient conditions affect a prepared area the resulting electrical characteristics can be detected and measured accurately using on-chip circuitry.
The acquisition complements Silicon Labs’ recent acquisition of MEMS maker Silicon Clocks Inc. (see Silicon Labs buys MEMS firm), according to Mark Downing, vice president of strategy and business development for Silicon Labs.
ChipSensors’ patented technology is suitable for use in thermostats, automotive climate control, printers, security systems, gas leak detection, and wireless sensor networks. And as it is compatible with conventional CMOS, just as Silicon Clocks MEMS are, there is the option of forming wireless sensor network nodes on a single die, including sensors, signal conditioning circuits and RF transceiver functions, together with the microcontroller and memory, integrated and calibrated in a single CMOS IC. "Monolithic is a key part of our strategy," said Downing although he said that initially Silicon Labs would produce ChipSensors’ stand-alone humidity and temperature sensors.
"Joining forces with Silicon Labs provides us with an exceptional opportunity to both collaborate with a team that has a reputation for the highest caliber mixed-signal engineering and potentially grow the design team in Ireland to take advantage of the strong local technical talent,” said Tim Cummins, CEO and founder of ChipSensors. Cummings is due to take on a product line director role for Silicon Labs.

"ChipSensors is a pre-revenue company.

Their humidity and temperature sensors had been sampling from MPW [multi-project wafer]. They have done enough to demonstrate the technology. Now we can step it on to its own mask-set and achieve qualification for various applications. We can also take the prototype package through to manufacture with a T&A partner." Downing said he expected to be in volume with parts in the second half of 2011.
Silicon Labs with retain ChipSensors’ Limerick office. "We will retain all the full-time employees and add to the staff to build up the capability," said Downing.
