How To Receive Multiple Sensor Readings From Your ARDUINO Into Your MIT APP INVENTOR 2 APP

7 років тому

The following tutorial will show you how to receive multiple sensor readings from your arduino board into you MIT APP INVENTOR 2 APP.
If you are using more than one sensor with your Arduino project you have found that it is necessary to send that data and display it on your app. To do this you will need to send all the sensors data at one time, then split it apart and display it in the appropriate fields in your MIT APP INVENTOR 2 APP. THIS IS HOW YOU DO IT!!!!!!
In this tutorial we will be using a DHT-11 (DHT11) temperature and humidity sensor and a Photo resistor to send 3 different readings to the mit app inventor app. A DHT-22 (DHT-22) temp and humidity sensor can also be used and it is more accurate than the THD11.

Thank you sooooo much!This example is awesome!I have incorporated it into a project that monitors the temperature of a refrigerator and now it monitors the door open / closed too!!!AWESOME!-Rob

Thanks a lot, Z-HUT!! I was having a hard time finding out how to read values from multiple sensors, this tutorial cleared it all.

This has been helpful. I just started working with App Inventor a couple of days ago, trying to get this ESP32-controlled guitar pedal to accept Bluetooth commands. I couldn't figure out how to get the pedal to communicate with the mobile device, but the part of your video that utilized global variables being input into a list helped me figure it out with my current setup. Thanks!

Hello, this clip made it for me. Now i can display my temp-sensors on the android device. But still a few problems i have to solve. by using your way i can´t compare the temperatur sended via bluetooth with a fixed value. the plan was to change colours by high temp or low temp. i also have a LCD Display connected whitch should be turned on / off if BT-connection is cut or by switch.

@z-hut1663 7 років тому

arduino board is 5 volt logic and the HC-06 or HC-05 is 3.3 volts logic, use the converter or A voltage divider and you will be good to go. if yoy use 5 volt logic into the HC-06 or HC-05 you distroy it after a short time....

@codewithjc4617 7 років тому

Shoot, actually i've been using 5v from my arduino and connecting it directly to my hc 05 and it doesn't send Any data, i mean, it turns on, and it connects yo the app but i don't receive Any data on my phone, i guess i burned it, thanks so much for the info men! Great videos, and just another question, what about if i connect the vcc of my hc 05 to the 3.3v pin of my arduino?
