New Product Roundup – December 11th to December 17th

We are back with another New Product Roundup! This will be the last New Product Roundup before the holidays as Saturdays for the next two weeks are overshadowed by Christmas Eve and New Years Eve. We have just a few products to talk about this week – so lets get to it!

SparkFun Particle Sensor Breakout – MAX30105

The SparkFun Particle Sensor is like the Swiss-Army Knife of sensors – it can do so much in such a small space! It can measure your heart rate, blood oxygen saturation level, the blinking of your eye, presence detection, air quality (smoke & other particles), and even distance sensing up to 18″. The sensor works based on three LEDs and a sensitive photon detector; by pulsing different LEDs and seeing what returns it is possible to sense all sorts of different things! As always, SparkFun has extensive documentation, example code, and an Arduino library to help get it running.

Heat Sink Compound

Next we have a 5g syringe of thermal paste. This paste is a blend of 50% silicone, 20% carbon, and 30% metal oxide and has a thermal conductivity of 1.172 W/(mK). It is designed to help efficiently transfer heat to heatsinks. This thermal paste should be sufficient for most voltage regulators, MOSFETs, motor drivers, audio amplifiers, and such.
