Introduction The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +/-16 g. Digital output data is formatted as 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface.
ADXL345 Datasheet Hardware Overview Features
Supply Voltage: 2.0 - 3.6 VDCUltra Low Power: As low as 23 uA in measurement mode, 0.1uA in standby mode at 2.5VSPI or I2C Communication Single Tap / Double Tap Detection Activity / Inactivity Sensing Free-Fall Detection The ADXL345 has special sensing abilities! The single and double tap sensing detects when a single, or two simultaneous, acceleration events occur. Activity and inactivity sensing detect the presence or lack of motion. Free-fall sensing compares the acceleration on all axes with the threshold value to know if the device is falling. All thresholds levels that trigger the activity, free-fall, and single tap/double tap events are user-set levels. These functions can also be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.
The ADXL345 is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°. Furthermore, low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on.
Peltier module - Features & Specifications:
·                     Model: TEC1-12715.
·                     Operates Temperature: -40degree to 90degree
·                     Operates from 0~15.4V DC and 0~15A
·                     Rated Voltage: 12V
·                     Rated Current: 15A
·                     Max power consumption: 165 Watts 
·                     Material: Plastic + ceramics
·                     Color: White
·                     Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler.
 These devices must be used in conjunction with a heat sink to avoid burned
· One side is cooling (Printed model number)and another side is heating (Printed no word) when working.
· Please radiating the heating side, avoid using under no-radiating condition over 2s\Coated with thermal grease when install the device
· Cable length: 20cm
· Dimensions: 1.57 in x 1.57 in x 0.12 in (4.0 cm x 4.0 cm x 0.3 cm)
 
Installation: Before installation, you must provide a dry environment and allow for any condensation from the cold side to drain away and not to come in contact with the operating cell. Connect the two leads of the Peltier cell to an appropriate power supply and importantly, observe the correct lead polarity and attach an adequate heat-sink with a quality thermal conducting grease applied to the warm side of the cell; you will feel the warm side and the opposite cool side of the operating cell. It is important to identify both the correct lead polarity and the cooling/heating sides of the device. If you want a greater cooling differential, it is recommended to use two Peltier cells, namely, one stacked above the other with the hot side of the upper cell in contact with the cool side of the lower one; an experiment proved the two stacked cell cooling effect is much better than the single-stage. Similarly a three cell stack produces an even greater temperature differential but requires a larger capacity power supply support.  Notes:·Power ON the device only with proper Heat-sink setup to avoid any burning/damage or malfunction of the device!·Use a good quality heat sink (such as in CPU fans) with thermal paste and power the device.·Use a 12 VDC Power supply to power the TEC1-12715.·Use 1A battery for 10-20 seconds to power ON the device to find the hot /cold side. 
Package Include:1 x TEC1 – 12715 Peltier Cooler Heater module.

Description
This sensor board has a voltage regulator. When using 3.3V to the VCC the resulting voltage (after the onboard voltage regulator) might be too low for a good working I2Cbus. It is preferred to apply 5V to the VCC pin of the sensor board. The board has pull-up resistors on the I2C-bus. The value of those pull-up resistors are sometimes 10k and sometimes 2k2. The 2k2 is rather low. If it is combined with other sensor board which have also pull-up resistors, the total pull-up impedance might be too low.
