I am doing one project where i have to send DHT11 sensor data to web server via POST method. Data should be sent after every 3 mins. I am using GSM SIM900A wih Arduino Uno for this. I am new to this GSM SIM900A module. Kindly help me in this. Please suggest me how do I upload data. I have one normal API also(not from thingspeak).
Thanks in advance.
