[DEMO] Request Sensor Data via SMS using Arduino and SIM900 GSM Shield
For complete project details (schematics + source code), visit ► https://randomnerdtutorials.com/reque...
In this project you'll request sensor data via SMS with Arduino. As an example we're going to request the temperature and humidity from a DHT sensor. To send and receive SMS with the Arduino we're going to use the SIM900 GSM shield. When you send an SMS to the Arduino, it replies with temperature and humidity readings.
