1.8V TMD3702VC to very low levels. In Sleep mode, the device draws just 0.7µA. A new translucent mold-compound package used in the TMD3702VC provides a very wide ±48° field of view. The proximity engine features wide dynamic range, ambient light subtraction, and advanced optical crosstalk noise cancellation which dynamically eliminates both electrical and optical crosstalk producing reliable proximity detection. The advanced optical sensor architecture of the TMD3702VC underpins the device’s accurate measurement of the Correlated Color Temperature (CCT) of ambient light. The ambient light and color sensing function includes four concurrent ambient light sensing channels – red, green, blue and clear – which all have a UV/IR blocking filter. Sensitivity, power consumption and noise are optimized with adjustable timing and power. The module accurately measures ambient light and enables the calculation of illuminance and color temperature values which support a smartphone’s management of its display’s appearance. “Today’s smartphone industrial design trend of maximizing a display screen size by increasing its screen-to-body ratio and minimizing the bezel area calls for the smallest module solution. The TMD3702VC with its ultra-small form factor facilitates this need, helping to almost eliminate the bezel on the display’s face,” said Dave Moon, Senior Product Marketing Manager at ams. “The TMD3702 helps phone designers minimize the space allocated to front-side ambient light and proximity sensing by providing them with a solution that is >60% smaller than the previous generation of products.” The TMD3702VC is available for sampling now. Unit pricing is $1.15 in order quantities of 1,000 units. For more technical information and to request samples or an evaluation board, go to https://ams.com/TMD3702VC.

Samsung Electronics Expands Horticulture LED Lineups to Advance Greenhouse and Vertical Farming Samsung Electronics, a world leader in advanced digital component solutions, today announced new horticulture LED lineups, including full-spectrum packages and modules as well as color (monochromatic) LEDs. Optimized for lighting in greenhouses and vertical farming*, the new LEDs provide a broader spectrum of light for healthier plant growth, enhanced farming environments and reduced lighting system costs. Full-spectrum light encompasses a continuous range of wavelengths from blue and green to red, creating a light blend suitable for horticultural uses. Compared to narrow spectrum lighting, Samsung’s full-spectrum-based LEDs encourage healthier and more balanced plant growth by stimulating photosynthesis, enhancing plant immunity and increasing nutritional value. Additionally, the LEDs can help to improve the overall farming environment by enabling growers to observe plant conditions more easily and spot diseases, like damping-off, at an earlier stage under bright white lighting. As high-efficiency and cost-effective alternatives to higher-priced red LEDs, full-spectrum LEDs can help lower the costs of a grower’s entire lighting system. “Samsung’s full-spectrum-based horticulture LEDs present a new way of using LED lighting to improve plant cultivation at reduced system costs,” said Un Soo Kim, senior vice president of LED Business Team at Samsung Electronics. “We plan to further expand our horticulture offerings by integrating the latest in smart LED lighting technology, including Samsung’s leading sensor and connectivity solutions.” In addition to its full-spectrum white LEDs, Samsung has added blue, red and far-red LEDs to its horticulture family to offer an extensive variety of wavelength combinations and meet the different design needs of horticulture lighting manufacturers. Built on Samsung’s market-proven LED technologies, the new full spectrum and color LED lineups feature a high degree of reliability, making them well-suited to withstand high temperatures and humidity levels as well as agricultural chemicals used in greenhouses and vertical farming. Samsung’s horticulture LED packages are now in mass production for lighting manufacturers and growers worldwide. The modules will become available in the first quarter of 2019.
