Mass air flow MEMS sensors cover the 30 to 1000 sccm range
February 27, 2012 // Julien Happich
Posifa Microsystems launched a new line of mass air flow sensors, the PMFc3000 family, presented as a pin compatible upgrade to the Honeywell AWM3000 series. The device incorporates the latest MEMS and microelectronics innovations, replacing the common “membrane-cavity” structure with a proprietary “solid-state” thermal isolation process which brings new levels of reliability.
The PMFc3000 offers an initial output tolerance off less than 2% full scale. The sensor die uses a pair of compound thermopiles surrounding a central heating element to detect changes in temperature gradient caused by mass flow, delivering excellent signal-to-noise, and unsurpassed repeatability. The sensor's internal signal conditioning circuitry leverages an off-the-shelf microcontroller, providing proven reliability and low cost. The unit covers the ranges from 30 to 1000 sccm (standard cubic centimeter/minute) and can be special ordered with any full scale range between 10 and 2,000, balancing customers’ need for performance and cost efficiency. The sensors are fully calibrated and compensated over the temperature range of 0 to 50ºC

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
