Just wanting to know what i require. I would like to measure the weight of something via load cells, scale this through an arduino board to kg and at set time ( e.g once a week) send this measurement to an email address. i notice you have the Arduino GSM Shield which is capable of sending sms is this also capable of sending emails? also with that, am i able to request a reply of weight upon command?
Basically what products do i need?
Okay, your mileage may vary :), however I would approach it with:
- find out what interface the load cell requires (i.e. what does it supply - is it an analogue signal or a a digital stream or Serial ....?) this will determine how you connect the load cell to the project.
- You will need to probably use the map function to scale accordingly (remember to include some kind of calibration function to set it up right)
- Then you can send an email via the GSM shield (have a look at this example and substitute the GSM library classes instead of the ethernet)
- So if you can send an email - you can reverse it to revieve and email and parse the text for a key word and the do something....
SO I would start with a MEGA Arduino (the Uno has too little memory to be really useful, a GSM shield and probably a prototype shield so wire the load cell to and to maybe add a buzzer or LED to show someone it is working), You will need an external power supply 12V 2A at least and this should be good to go!
