I am at the begining of a project, I am looking for a good sensor that measures electromagnetic field for each minute or hour. when i found the sensor, i will need the measurements to be sent somewhere from where i will be able to see them from my house and to process them. Also when it passes a certain limit, i would like an sms to be sent on my mobile phone. Do you know any sensor or any other instruments or manuals to recommend me?
Thanks, I am waiting for your response
