This is a breakout board for Honeywell s HMC5843, a 3-axis digital compass. Communication with the HMC5843 is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.5-3.3VDC should be supplied. The breakout board includes the HMC5843 sensor and all filtering capacitors as shown. The power and 2-wire interface pins are all broken out to a 0.1″ pitch header.

This breakout board is the simplest way to create a project with mutiple capacitive touch sensors. No microcontroller is required here – just power with 1.8 to 5.5VDC and connect up to 5 conductive pads to the 5 left-hand pins. When a capacitive load is detected (e.g. a person touches one of the conductive contacts) the corresponding LED on the right lights up and the output pin goes low. You can use this to update an existing normal-button project where buttons connect to ground when pressed.
This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
Unlike all the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it! Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. The embedded thermopile sensor generates a very very small voltage depending on how much IR there is, and using some math, that micro voltage can be used to calculate the temperature. It also takes the measurement over an area so it can be handy for determining the average temperature of something.
