Peripherals/Sensors

There are a large variety of sensors which can be added to the XO using the MIC_IN port. These may include;

Touch/Pressure - Extended information
Light - Use it for inverse square law experiments or for studying polarizers, reflectivity, or solar energy.
Temperature
Humidity
Barometer - Can be used for either weather studies or for lab experiments involving pressures close to normal atmospheric pressure
Soil Moisture Sensor - Some soil moisture sensors use capacitance to measure the water content of soil
Hall Effect (magnetic field) sensors - By using a rotating sensor tip it is possible to measure both transverse and longitudinal magnetic fields.
Oscilloscope - With amplification?
Ultrasonic - Water level monitoring, create real-time motion graphs of position, velocity and acceleration.
