MMS Electronics has available a new range of digital temperature sensors from Smartec BV. The SMT172 is an ultra-low power, fully calibrated, high accuracy digital sensor. Using the most recent advances in silicon temperature sensing technology, the SMT172 has applied sophisticated IC design techniques and high-precision calibration methods, to achieve an absolute inaccuracy of less than 0.25ºC in the range of -10 ºC to 100 ºC. Full temperature range is -45ºC to 130ºC. The sensor operates with a supply voltage from 2.7 to 5.5V. With a typical active current of only 60uA, high speed conversion over 4000 outputs per second (at room temperature) and extremely low noise, makes this the most energy efficient temperature sensor in the world. The SMT172 has a pulse width modulated output signal, where the duty cycle is proportional to the measured temperature. The sensor can connect directly to a Micro-processor without an Analog-to-Digital Converter. The SMT172 replaces the SMT160-30.

Unpopulated Arduino shield for the popular EA DOG displays are now available. The support documentation includes circuit diagrams, EAGLE PCB layouts, component placements, initiation sequences and sample programs for operating the display on an Arduino Uno. Three different size shields are available. There is a display shield for the EA DOGM081-A (1x8), EA DOGM162-A (2x16) and EA DOGM163-A (3x16) with ST7036 controller. The 2nd shield is for EA DOGM132-A (132x32), EA DOGM128-6 and EA DOGL128-6 (128x64) graphic displays with ST7565R controller. The 3rd shield is for the EA DOGS102-6 (102x64) graphic display with UC1701 controller.

Displays with a PCAP capacitive touch-screens are now available. The part number is EA eDIPTFT43-ATC (4.3") and the EA eDIPTFT70-ATC (7.0") intelligent graphic display. The EA eDIP intelligent displays can be supplied with the traditional resistive touch-screen or a PCAP capacitive touch panel. The capacitive touch-screen version is brighter and higher contrast then the resistive version. The displays with PCAP touch panel displays have an elegant black surround bezel.

The intelligent EA eDIPTFT43-A TFT graphic display with capacitive touch panel and elegant black surround can be used with or without gloves. . The display with 6H surface hardness is absolutely scratch-proof and is designed for day-to-day use in harsh industrial environments. Multi-touch is detected but does not result in operating errors. The EA eDIPTFT43-A has a diagonal screen size of 4.3 inch (10.9 cm) with resolution of 480 x 272 pixels and a 16-bit color depth supports up to 65,536 colors. LED backlighting ensures bright, high-contrast images.
The display can be used in horizontal (480x272) or vertical view (272x480). The orientation is software selectable. Simple commands offer an abundance of clever graphics functions for displaying bargraphs, frames, switches, analogue rotary and pointer instruments. Eight predefined fonts are provided and other TrueType fonts can be imported. The onboard 4MB memory stores images, animations and macros. Text can be mixed with graphics, pictures and gif animations. The display features 8 digital inputs, 8 digital outputs and 2 analogue inputs. Interface is serial, SPI or I2C. An evaluation kit EA EVALeDIPTFT43-ATC is available for effortless development.
