The MPX2100 series device is a silicon piezoresistive pressure sensor providing a highly accurate and linear voltage output — directly proportional to the applied pressure. The sensor is a single, monolithic silicon diaphragm with the strain gauge and a thin–film resistor network integrated on–chip. The chip is laser trimmed for precise span and offset calibration and temperature compensation. Features • Temperature Compensated Over 0°C to 85°C • Easy–to–Use Chip Carrier Package Options • Available in Absolute, Differential and Gauge Configurations • Ratiometric to Supply Voltage • ±0.25% Linearity (MPX2100D) Application Examples • Pump/Motor Controllers • Robotics • Level Indicators • Medical Diagnostics • Pressure Switching • Barometers • Altimeters

The MPX5010DP is a dual port, integrated silicon pressure sensor in 6 pin SIP package. This piezoresistive transducer is state of the art monolithic silicon pressure sensor designed for wide range of applications. It is ideally suited for microprocessor or microcontroller based system. This transducer combines advanced micromachining techniques, thin-film metallization and bipolar processing to provide an accurate, high level analogue output signal that is proportional to applied pressure. The axial port has been modified to accommodate industrial grade tubing. >On-chip signal conditioned, temperature compensated and calibrated >Differential configuration >5.0% maximum error over 0°C to 85°C >Durable epoxy unibody >Temperature compensated over -40°C to 125°C >Patented silicon shear stress strain gauge >Pressure range from 0KPa to 10KPa >Supply voltage range from 4.75VDC to 5.25VDC >Sensitivity of 450mV/mm >Response time of 1ms

It is an easily cascadable 8×8 monochromatic LED dot matrix display module with onboard MAXIM’s MAX7219 LED driver chip. The MAX7219 allows you to drive the LED matrix using only three I/O pins of Arduino or any other microcontroller. The LED matrix module used in Easy Matrix has a bigger dot size (5mm) and has the overall display dimensions of 60.2mm x 60.2mm (2.4″x2.4″). It is easily cascadable in series with the help of precisely aligned male and female header pairs located on the left and right sides of the display module. With lots of freely available Arduino libraries for MAX7219 chip, this module is easy to use in any Arduino project for displaying basic text and animation.
