Overview

What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.

Best temperature sensor under $10 Review by Nick
This device works on 1-Wire networks and comes with it's own serial number (equivalent to a MAC id for a PC on a network).

Hard to imagine this thing that is as small as a transistor has it's own little micro controller on board with ROM but it does! You can query it's ID number with each temperature reading and request a reading from it by ID. This enables you to use 1,000 or more of these temperature controllers on the SAME *single* I/O pin!

Plays nice with other 1-wire devices too (I have put it on a network with another temperature sensor and 4k memory module, all using the same 1 pin... just unbelievable.

1-wire networks couldn't be simpler... just give each device ground and power, and connect them all to the same data line, and you're done. They will communicate on the network by ID request and can talk back and forth without data collision.

This is also accurate to about 1/5th of a degree, and responsive enough to about a new reading every 1/5th of a second (anything higher and it seems to return identical data). You can breathe on it and watch the temperature rise about 4 degrees and drop back down within a few seconds. You can place it close to but not touching your body and watch it raise about half a degree. VERY sensitive. Couldn't ask for much better than this!

This unit comes with both 3 and 4 pin connectors and 1 screw mount hole for easy placement, and also comes with SMD mounted cap and resistor to make it play extra nice. Very nice design by Itea Studios! (Posted on 7/20/2013)
