In the above image the resistor to the left of the vertical dashed line (R1) is found on the pressure sensor module. The majority of 4-20 mA sensors work in the 9-24 V range. Arduino Tutorial 9 – Reading Sensors Background - In tutorial 3, with the LCD shield plugged in - when you pressed one of the 5 buttons we were able to read which button on the LCD shield was pressed. (Arduino(is(an(easy(to(use,(cheap,(versatile(and(powerful(tool(thatcan(be(used(to(make(some. MATLAB ® can be used to quickly analyze and visualize data collected from sensors connected to Arduino ®. Displaying temperature on arduino lcd keypad shield. While using the sensor module with the Arduino, we include Wire. Measuring temperature with ds18b20 temperature sensor and arduino. Interfacing SPD005G pressure sensor to arduino. We developed two different matrix sensors for Snowboard - a 10x7 matrix sensor with wide dynamic range and a 16x10 matrix sensor with low force detection. Then download our MPL115A2 Arduino library and example code for temperature, pressure and basic altitude calculation. You should be wondering the reason why it says BMP085 while we are using the sensor BMP180. In tutorial 5, using an Infra Red detector - we could tell which button on the remote control was pressed.
