There are lots of places the Melexis parts don't fit. Notebooks, netbooks, smartphones, OEM's wallets, etc.

To @premix: very interesting info, will you be interested in presenting your product info at emerging technologies conference in Vancouver in 2012? www.cmoset.com, also, I am editing a book on sensors, would you be interested in contributing a chapter? Kris

We welcome TI to the market but modestly note their device is a late entry. Melexis has been making and selling fully integrated and calibrated single chip MEMs IR sensors/thermometers for 5+ years. And multi chip solutions for even longer. The MLX90614 and MLX90615 pioneered the integrated chip application space. Biggest difference is packaging. TI's package seems to limit applications opportunities. Automatic Climate Control in cars has millions of MEMs IR Temp sensors at work. All major race car teams (F1,Indy,NASCAR) use the MEMs IR sensors from Melexis for measuring tire temperature to optimize suspension and maximize tire life. Then there are Medical applications in body temperature measurement with as example controlling spread of SARS virus in Asia by scanning passengers boarding public transit systems. I can finally confirm that MEMs IR temp sensors are very useful in white goods too.

elPresidente: it's not intended as the solution to all temperature-measurement situations, it's another powerful tool in the engineer's kit. And "radiated temp of objects nearby" applies to many situations.

It does not have the ambient temperature or distance range to be of much use. It also cannot measure air temperature, just radiated temperature of objects. Useless in a fridge, oven, and coffeemaker, IMO.

This device can go into fridge,oven,AC's,washing machines,grinders,cofeemakers and many kitchen gadgets. The non contact temperature measuring is highly advantageous in many situations.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
