IoT Project: DIY, Net-Connected Wireless Water Heater

Some people like to remotely start their cars when it’s cold outside. Dan Beadle took this idea one step further by Internet-enabling his mountainside retreat’s hydronics system. The innovative design enables him to warm the house well in advance of his arrival.

Serving up the current temperature involves several computers, a Wi-Fi access point, and the DPAC Airborne module.

Serving up the current temperature involves several computers, a Wi-Fi access point, and a DPAC Airborne module.

In “Wireless Water Heater” (Circuit Cellar 163), Beadle writes:

My mountain home, where I have vacationed for years, is well insulated, making it a snap for the heater system to keep warm. I have a small, efficient heater; however, it takes forever to warm the house from a 50°F standby to a livable 68°F. Typically, I arrive late and shiver in my jacket for three or four hours until the house warms up—and that does not warm the entire house, just the portion needed to get through the night.

I had been thinking for a while about Internet-enabling the system. The idea was to turn on the heater before we start up the mountain. I have DSL at the house with a fixed IP. So, it seemed like it would be a simple task to enable a thermostat. I considered using an X10 thermostat, but, after a few of our X10-enabled lights found a mind of their own, I decided that I wanted better reliability. My next thought was to use simple copper to do the hook-up. I started planning a cable from my office/DSL entry up to the logical thermostat location. Then I procrastinated. I could not bring myself to run the wires along the surface of my redwood paneling. (And it was not at all feasible to remove the paneling.) Wireless makes the problem a lot simpler: there are no wires to run, and the applications processor and digital I/O on the module make the hardware design trivial.

Happy Gecko MCU Family Simplifies USB Connectivity for IoT Apps

Silicon Labs recently introduced new energy-friendly USB-enabled microcontrollers (MCUs). Part of its EFM32 32-bit MCU portfolio, the new Happy Gecko MCUs are designed to deliver the lowest USB power drain in the industry, enabling longer battery life and energy-harvesting applications. Based on the ARM Cortex-M0+ core and low-energy peripherals, the Happy Gecko family simplifies USB connectivity for a wide range of Internet of Things (IoT) applications including smart metering, building automation, alarm and security systems, smart accessories, wearable devices, and more.SiliconLabsEFM32

Silicon Labs developed the Happy Gecko family to address the rising demand for cost-effective, low-power USB connectivity solutions. With more than 3 billion USB-enabled devices shipping each year, USB is the fastest growing interface for consumer applications and is also gaining significant traction in industrial automation. In today’s IoT world, developers have discovered that adding USB interfaces to portable, battery-powered connected devices can double the application current consumption. Silicon Labs’ Happy Gecko MCUs provide an ideal energy-friendly USB connectivity solution for these power-sensitive IoT applications.

Happy Gecko USB MCUs feature an advanced energy management system with five energy modes enabling applications to remain in an energy-optimal state by spending as little time as possible in active mode. In deep-sleep mode, Happy Gecko MCUs have an industry-leading 0.9-μA standby current consumption (with a 32.768-kHz RTC, RAM/CPU state retention, brown-out detector and power-on-reset circuitry active). Active-mode power consumption drops down to 130 µA/MHz at 24 MHz with real-world code (prime number algorithm). The USB MCUs further reduce power consumption with a 2-µs wakeup time from Standby mode.

Like all EFM32 MCUs, the Happy Gecko family includes the Peripheral Reflex System (PRS) feature, which greatly enhances overall energy efficiency. The six-channel PRS monitors complex system-level events and allows different MCU peripherals to communicate autonomously with each other without CPU intervention. The PRS watches for specific events to occur before waking the CPU, thereby keeping the Cortex-M0+ core in an energy-saving standby mode as long as possible, reducing system power consumption and extending battery life.

Happy Gecko MCUs feature many of the same low-energy precision analog peripherals included in other popular EFM32 devices. These low-energy peripherals include an analog comparator, supply voltage comparator, on-chip temperature sensor, programmable current digital-to-analog converter (IDAC), and a 12-bit analog-to-digital converter (ADC) with 350 μA current consumption at a 1 MHz sample rate. On-chip AES encryption enables the secure deployment of wireless connectivity for IoT applications such as smart meters and wireless sensor networks.

The Happy Gecko family’s exceptional single-die integration enables developers to reduce component count and bill-of-materials (BOM) cost. While typical USB connectivity alternatives require external components such as crystals and regulators, the highly integrated Happy Gecko MCUs eliminate nearly all of these discretes with a crystal-less architecture featuring a full-speed USB PHY, an on-chip regulator and resistors. Happy Gecko MCUs are available in a choice of space-saving QFN, QFP and chip-scale package (CSP) options small enough for use in USB connectors and thin-form-factor wearable designs.

The Happy Gecko family is supported by Silicon Labs’ Simplicity Studio development platform, which helps developers simplify low-energy design. The Simplicity Energy Profiler enables real-time energy profiling and debugging of code. The Simplicity Battery Estimator calculates expected battery life based on an application profile, energy modes and peripherals in use. The Simplicity Configurator provides a visual interface for MCU pin configuration, automatically generating initialization code. Code developed for other EFM32 MCUs can be reused with Happy Gecko applications. Developers can download Simplicity Studio and access Silicon Labs’ USB source code and software examples at no charge at www.silabs.com/simplicity-studio.

To help developers move rapidly from design idea to final product, the Happy Gecko family is supported by the ARM mbed ecosystem, which includes new power management APIs developed by Silicon Labs and ARM. These low-power mbed APIs are designed with low-energy application scenarios in mind, enabling rapid prototyping for energy-constrained IoT designs. ARM mbed APIs running on EFM32 MCUs automatically enable the optimal sleep mode based on the MCU peripherals in use, dramatically reducing system-level energy consumption. The Happy Gecko starter kit supports ARM mbed right out of the box. Silicon Labs has also launched mbed API support for Leopard, Giant, Wonder and Zero Gecko MCUs.  For additional ARM mbed information including access to mbed software, example code, services and the mbed community, visit www.silabs.com/mbed.

The Happy Gecko family includes 20 MCU devices providing an array of memory, package and peripheral options, as well as pin and software compatibility with Silicon Labs’s entire EFM32 MCU portfolio. Samples and production quantities of Happy Gecko MCUs are available now in 24-pin and 32-pin QFN, 48-pin QFP and 3 mm × 2.9 mm CSP packages. Happy Gecko MCU pricing in 10,000-unit quantities begins at $0.83. The Happy Gecko SLSTK3400A starter kit costs $29.

Customers can use the SIGFOX network with TI’s Sub-1 GHz RF transceivers to deploy wireless sensor nodes that are lower cost and lower power than 3G/cellular connected nodes, while providing long-range connectivity to the IoT.TI - SIGFOX

Targeting a wide variety of applications ranging from environmental sensors to asset tracking, the SIGFOX and TI collaboration maximizes the benefits of narrowband radio technology. It also reduces barriers to entry for manufacturers interested in connecting their products to the cloud. Using the SIGFOX infrastructure reduces the cost and effort to get sensor data to the cloud and TI’s Sub-1 GHz technology provides years of battery life for less maintenance and up to 100 km range.

SIGFOX’s two-way network is based on an ultra-narrowband (UNB) radio technology for connecting devices, which is key to providing a scalable, high-capacity network with very low energy consumption and unmatched spectral efficiency. That is essential in a network that will handle billions of messages daily.

TI’s CC1120  Sub-1 GHz RF transceiver uses narrowband technology to deliver the longest-range connectivity and superior coexistence to SIGFOX’s network with strong tolerance of interference. Narrowband is the de facto standard for long-range communication due to the high spectral efficiency, which is critical to support the projected high growth of connected IoT applications. The CC1120 RF transceiver also provides years of battery lifetime for a sensor node, which reduces maintenance and lowers the cost of ownership for end users.
