Ben's HobbyCorner - Software - Bascom-examples On the right the ADXL345, connected to the I2c-bus, and when connected well, you will find it in the I2c-scanner. This is the Bascom-AVR code for the I2c-scanner. When the ADXL345 and the HMC5843 are fixed on the board you should see this in Hyperterminal.

Erlich Industrial Development Corporation
Erlich Industrial Development Corporation (EID) is an OEM manufacturing and R&D Company specializing in the development of high technology biological, medical and chemical research products.
Adjustable Output Positive Voltage Power-Supply Kit
An electronics board (kit) that allows you to connect up to 30V AC or DC on one side of the board and get adjustable VDC regulated on the other side. Every lab should have a few of these boards handy. The boards will allow you to easily power all your analog components (i.e. op-amp). The Terminal Block TB connector is included and makes it easy to use.
Interface board conductivity cell with DIN Rail clip
Build your own Conductivity meter and/or controller and save. Simply connect your Conductivity cell (conductivity electrode, Probe) to the input via Terminal Board (TB) and the output to analog to digital converter (ADC), Digital voltmeter (DVM), Analog Voltmeter, micro-controller (MC) or PLC. Power the board and get reading.

Allegro MicroSystems - Power ICs and Hall-effect sensors
Sanken Products include Regulator ICs, Switching Regulators, Off-Line Flyback Regulators, Stepper Motor Unipolar Drivers, Inverter Power Modules.
50 to 200 A Integrated Conductor Sensor ICs
"The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer."

LM335 Cold Junction Compensation
Another Method using a Copper Resistor
If wires of two dissimilar metals are joined at both the ends and the junction formed at one of the ends, is heated more than the other junction, a current flows in the circuit due to Seebeck thermal emf. This effect is used in thermocouple temperature sensors.
The Peltier effect is the converse of above Seebeck effect, which means that if a current is forced through junctions of dissimilar metals, the junction will generate heat or absorb heat (cooling) depending on direction of the applied emf. This effect is used to make portable and small refrigerators.
