    This is a breakout board for Freescale's MMA7361L three-axis analog accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ?1.5g and ?6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices....

    This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125 degree, the cable is jacketed in PVC so we suggest keeping it under 100 degree. Because they are digital, you don't get any signal degradation even over long distances! The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and...

Wind & Water Power Turbines Description: The Wind & Water Power Turbines convert the wind & water to the mechanical energy and then convert to electricity power. This mini Turbines outputs small power for small projects such as LED, suitable for DIY projects. Note that the output of the turbine is AC, Rectifiers are needed if you want to change it into DC. As we tested, the turbines can power 5 LEDs with a wind speed 20 km/h, and 10 LEDs with a wind speed 50 km/h. you can use this...
