Vernier Coding Activities with Arduino®: Analog Sensors

The Vernier Arduino Interface Shield provides a convenient way to make connections from Arduino microcontrollers to Vernier sensors. The Vernier Arduino Interface Shield plugs directly on top of the Arduino and adds two BTA (analog) and two BTD (digital) sockets. This shield was developed to be used with the SparkFun Arduino RedBoard but will work with the Arduino Uno and other Uno equivalents like the Leonardo. It also works with the Intel Galileo. Sample code is provided on the Vernier website, which will support auto-ID for all Vernier sensors and will get you started with writing your own data-collection programs. Works with over 80 Vernier sensors with BTA and BTD connectors.

Description The SparkFun RedBoard is an Arduino™ UNO-compatible board, which is perfect for use with the Vernier Arduino Interface Shield. A USB Mini-B cable is included. The SparkFun RedBoard is an Arduino-compatible board that is perfect for use with the Vernier Arduino Interface Shield. It is a surface-mount board, which is pin-for-pin compatible with a R3 3 Arduino layout. The key difference between the RedBoard and most Arduino boards is that it uses a mini-B USB connector instead of a full-size type-B USB connector. The RedBoard operating voltage is 5 volts, which is required for use with most Vernier sensors. You can power the RedBoard either with the USB connector (included) or with a 7-15 V barrel jack power supply (not included). To use Vernier sensors with the SparkFun Redboard, you will need the Vernier Arduino Interface Shield.

Use the Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments. The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is sensitive enough to conduct vapor-pressure or pressure-temperature experiments. Biology teachers can use the Gas Pressure Sensor to monitor transpiration or respiration in an enclosed environment. Pressure Range:0 to 210 kPa (0 to 2.1 atm or 0 to 1600 mm Hg) Accuracy:±4 kPa User manual
