How to send sensor data from Arduino to smart phone?

The tutorial on NRF24L01 as RF module has already been explained in interfacing nRF24L01 with Arduino tutorial. Today the BLE functionality of this module will be explained by sending sensor data to a smart phone.

How to make an Android app for Arduino?

So I decided to make an android app that would send serial data to Arduino to change timings of water motor. In this instructable, I will explain how to create an android app that can communicate with Arduino by USB OTG cable, If you dont care about how to just download .apk file and install it in your phone to communicate with arduino.

How to send sensor data with Arduino and dht11?

Here this nRF24L01 module will be interfaced with Arduino Microcontroller and the DHT11 sensor temperature data will be sent to official Nordic BLE android application. The nRF24L01 modules are transceiver modules, meaning each module can both send and receive data but since they are half-duplex they can either send or receive data at a time.

How to send sensor data using Arduino and nRF24L01?

Start the serial port at 9600, you can choose any port. Then begin the DHT sensor and also begin BTLE with the Bluetooth Local Name with max 8 characters long. Read the temperature over the loop and save it to a float variable temp. Add a debug line for showing an error message if DHT loses its power or anything unexpected happens.

How to use Bluetooth for reading data on Arduino?

This tutorial demonstrates a simple way to make use of bluetooth for reading data in arduino projects. The aim of this tutorial is to gather sensor data from a simple temperature sensor and transfer it to the PC using bluetooth communication. On the PC side, a simple arduino sketch is written, which will be uploaded onto the arduino board.

What is an infrared sensor on an Arduino?

Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it What is an infrared sensor? An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings.

How to read analog sensors on an Arduino?

Feel free to adjust this delay to whatever interval makes sense for your application. Once you have the test code written, save the sketch and upload it to the Arduino. Open up the serial monitor and you should see values from 0-1023 depending on how bright or dark the area is.
