IMU - Accelerometers and Gyroscopes

The ADXL345 from Analog Devices is a small, thin, low power, 3-axis accelerometer with high resolution 13-bit measurement at up to ±16 g.

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.

Adjustable Output Positive Voltage Power-Supply Kit

Interface board conductivity

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

Interface board conductivity

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.

50 to 200 A Integrated Conductor Sensor ICs

ACS756 Fully Integrated Hall Effect-Based Linear Current Sensor

"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

Temperature Sensors like Thermocouples need cold junction compensation as a part of front end signal conditioning, this is done at the terminal block where the Thermocouple wires are terminated. This design has to be more accurate and broad, if the design we make has to work well in both Tropical and Temperate Climate Zones.

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. Thermocouple Temperature DPM - DMM
