Texas Instruments is making the case that it has within its portfolio all of the technologies that industry needs for a forthcoming “revolution” in the way that it is controlled, and operates. TI refers to the phenomemon that some have termed “Industry 4.0”. The same technologies underpin what electronics can offer to the connected home, and commercial premises; some of them are processing power, wireless connectivity, analogue technology and multi-dimensional sensing capabilities.

Each of these, TI argues, is a solution in its own right to an existing or emerging problem; but together, and with integration, they offer the possibility of fostering entirely new functions. Key to the emergence of new concepts, TI says, is the availability of all of the competent functions in low-power forms. Energy efficiency, device-device or machine-machine communications, building automation, the smart grid – and many of these systems will be very long-lived. TI points to its existing range in embedded processing, and in linear circuitry, and is promising continued development of products that are immediately applicable to the new trends in industrial electronics. The company will deliver system-level designs via its “TI Designs” catalogue and website, of ready-to-use (or ready-to-adapt) designs that are complete and the product, sub-system and also, system, level.

The sensor offering in this announcement comprises four devices that allow engineers to accurately sense key parameters in tight spaces with very low power. These new products provide solutions for temperature, humidity, ambient light and capacitive sensing in a host of industrial and enterprise applications.

next; low power thermopile, & humidiy..


The TMP007 is a highly integrated, non-contact infrared (IR) temperature sensor (thermopile), joining TI’s family of smallest thermopile sensors. This sensor features an integrated maths engine, which performs calculations on-chip for direct reading of the object’s temperature, and delivers low power consumption of 675 uJ per measurement. Measuring 1.9 x 1.9 x 0.625 mm, the TMP007 allows designers to monitor temperature in space-constrained industrial applications, including protection relays and process control equipment, and other factory and building automation applications, as well as enterprise equipment, such as laser printers and network servers. You can install a low-power, potentially battery-powered or energy-harvesting powered, in confined spaces that would not have been feasible previously, TI says.

Designers of building control equipment can implement accurate, energy-saving climate control in small spaces, while designers of home appliances and consumer goods can easily add humidity sensing capabilities to their products with the HDC1000 integrated humidity and temperature sensor. TI’s humidity sensor provides high accuracy and low power in a small, dust-resistant package. The HDC1000 consumes only 1.2 µA of average current when measuring relative humidity and temperature at 11-bit resolution, once per second. This low current can extend battery life in remote applications. The sensor’s 2.0 x 1.6-mm wafer level chip scale package (WLCSP) simplifies board design and minimises system size. Placement of the sensing element on the bottom of the device provides resistance to dust, dirt and other environmental contaminants.

next; ambient light, & C-to-digital


New usage scenarios are possible with the third sensing device, the OPT3001 precision ambient light sensor tuned to closely replicate the human eye’s photopic response. Its spectral response provides greater than 99% IR (infrared) rejection, to provide consistent light metering regardless of the light source. At 2.0 x 2.0 x 0.65 mm and operating down to 1.6 V at typical (average) operating current of 2 µA, the ambient light sensor can be used for a variety of battery-powered applications. OPT3001 enables measurement over a 23-bit effective dynamic range, giving designers the high resolution needed for enterprise, lighting control and building and factory automation applications. The new ambient light sensor is compatible with TI’s Sensor Hub BoosterPack (pictured).

The four-channel FDC1004 capacitance-to-digital converter offers low power and 16-bit noise performance, over a range of ±15 pF, which makes it easy for designers to use capacitive sensing to increase the intelligence and awareness of their systems. The device can support an offset capacitance of up to 100 pF, allowing for remote sensing in harsh environments or where electronics cannot be located. It includes a strong shield driver to help minimise interference, to help focus the sensing direction and reducing the impact of temperature variations on system performance. The FDC1004 can be used in many applications such as proximity wake-up sensing, material analysis and liquid level sensing. It is compatible with microcontrollers (MCUs), such as the ultra-low-power MSP430 MCUs.
