Hi guys! I’m using Arduino UNO and TinySine GSM SIM5320E model http://www.tinyosshop.com/3g-gprs-gsm-shield-for-arduino-sim5320e. I powered the GSM with 9 V 2 A adaptor and also using USB.
I have a code that works absolutely fine for sending SMS after using command ‘s’ in the serial monitor.
But can you please help in modifying the code, so that the GSM module can automatically send SMS to the mobile after the sensor (connected to A0 pin) hitting certain value (say 650 above)?
