Phone Sensors Module

This module allows you to access the following inbuilt sensors of your Smartphone:

Accelerometer
Gyroscope
Proximity sensor
Magnetometer
Light meter
Sound meter
GPS Location
Temperature sensor
Barometer

Introduction

This phone sensor module allows you to access the following inbuilt sensors of your smartphone: Accelerometer, Gyroscope, Proximity sensor, Magnetometer, Light meter, Sound meter, GPS, Temperature sensor and Barometer.

Accelerometer

Senses the acceleration acting on your Smartphone in all three directions (X-axis, Y-axis, and Z-axis) in m/s2.

Gyroscope

Senses the angular velocity in all three directions (X-axis, Y-axis, and Z-axis) in rad/s.

Magnetometer

Senses the magnetic field acting in all three directions (X-axis, Y-axis, and Z-axis) in µT. It can be used to move robots in a specific direction.

Proximity sensor

Senses if there is an object near your Smartphone. If the object is nearby, 0.0000CM is displayed. Otherwise, a different number depending on the default setting of your phone is displayed.

Light meter

Senses the light falling on your Smartphone in Lux.

Sound meter

Senses the intensity of nearby sound in dB. The module will ask you to provide audio record permission.

GPS

Shows the Longitude and Latitude of your current location. The module will ask you to provide location access permission.

Temperature sensor

Senses the temperature.

Barometer

Senses the pressure.

Sensor Block

You can get the phone sensors using a reporter block “get () reading”.

In its drop-down, you will find various parameter related to phone sensors.

Note: When you are using this module with Arduino Uno, Mega, and Nano, you have to set the Bluetooth baud rate to the baud rate of the Bluetooth module to have proper communication between the board and the module. To set the baud rate you have to use set Bluetooth baud rate to () block.

Example – Accelerometer

Displaying the values of Accelerometer parameters on TFT display.

Example – Gyroscope

Displaying the values of Gyroscope parameters on TFT display.

Example – Magnetometer

Displaying the values of Magnetometer parameters on TFT display.

Example – Light Sensor

Displaying the Light parameter on TFT display.

Example – Proximity Sensor

Sensing proximity and playing a tone on Buzzer accordingly.

Example – GPS Location

Displaying the values of GPS parameters on TFT display.

Example – Sound Sensor

Displaying the value of the sound parameter on TFT display.

Example – Temperature Sensor

Displaying the value of the Temperature parameter on TFT display.

Example – Barometer

Displaying the value of the Barometer parameter on TFT display.

Arduino

Header

To include the Sensors module in the Arduino program, you have to include the following header:

#define CUSTOM_SETTINGS

#define INCLUDE_SENSOR_MODULE

After defining the above mention headers, you have to include the dabble library:

#include <Dabble.h>

You can download the library from here:

Enabling Bluetooth Communication

To enable Bluetooth communication, you have to initialize serial communication using the following code:

Dabble.begin(Baud_Rate);

Here Baud_Rate is the baud rate set for the Bluetooth module. With evive, you normally get 115200 baud rate modules.

Refreshing the data

To refresh the data that the device has got from the mobile app, you have to use the following line of code:

Dabble.processInput();
