The MEAS weather shield with five environmental sensors on an Arduino/Genuino 101- and Uno R3-compatible board from TE Connectivity is available from Mouser Electronics. The five sensors are: the TE HTU21D digital relative humidity sensor, MS5637 digital barometric pressure sensor, TSYS01 temperature system sensor, MS8607 digital relative humidity and digital pressure sensor, and TSD305-1C55 digital thermopile sensor. The HTU21D sensor is a self-contained humidity and temperature sensor with selectable resolution that ...
Raytheon UK has developed a positioning and navigation system that adds 3D dead-reckoning to global navigation satellite systems (GNSSs, GPS for example), allowing navigation inside buildings. Called ‘Strider’, it comes in two parts – a ‘boot-mounted unit’ (BMU) and a phone app. Inside the BMU are MEMS accelerometers, gyros and a pressure sensor (height). This communicates with the ‘Strider Location ...
Texas Instruments has introduced what it claims are the industry’s first precision nano-power op amps. LPV811 consumes 450nA (typ) and offers 370µV (max, +/-60μV typ) offset, while offset in the dual LPV812 is 300µV. If more offset can be tolerated, there are even lower current versions – see below. The op-amp family is aimed at battery-powered sensors in building automation, ...
At Electronica next week, Panasonic is going to be showing the gate driver for GaN power transistors it has been talking about for months, and more. According to Panasonic: “Optimised for high frequency switching, the gate driver un-locks the full performance of the company’s line-up of 600V enhancement mode X-GaN transistors.” It will be interesting to see what form this takes, and ...
ON Semiconductor has shrunk the size of its latest CMOS image sensor in the Python family. Python 480, which will be on view at Electronica in Munich next week, has the same pixel design and SVGA (800 x 600 pixel) resolution as the existing Python 500, but comes in a package which is 85% smaller than the existing device. These ...
French lab Leti has teamed up with imaging firm Pyxalis to commercialise technology that lowers readout noise for image sensors to 0.5 electron noise and improves low-light image sensing capabilities. Dubbed ‘Owly-eyed’, it is based on a patented electrical pixel readout architecture that can be integrated in image sensors, which Pyxalis will offer it in its next range of CMOS ...
Peratech, the Yorkshire-based sensor materials firm, is collaborating with several notebook computer manufacturers to incorporate its 3D force-sensing technology. The firm is developing its QTC force sensors for use in notebook PCs. The sensors, which consist of nanoparticles printed and encapsulated in ultrathin (down to 50 µm) polymer membranes, can be configured to sense an X-Y position when touched lightly ...
Datum Electronics has built a record-breaking torque transducer, weighing 4.6tonnes and able to measure 10,000,000Nm (10MNm) torque. As a comparison, 80Nm of torque is needed to tighten a nut on your car wheel. The Isle of Wight firm developed it with Solent LEP and the UK Government’s Technology Strategy Board. An extension of Datum’s 425 Series, it offers accuracy to 0.01%, 24bit resolution ...
