We have a small project needed a solution.
a device which will send email upon pressing a single button.
this device should be as small as possible and cheap.
we are willing to pay to to some one to offer such solution.
what do you think ?
How Cheap is cheap ? What are you trying to do and why ?
What Internet infrastructure is going to be in place to actually send the email i.e. is there an ethernet cable to connect to ? or a wireless network infrastructure or do we need to go GSM ?
The easiest and cheapest is to use an Arduino Nano and a TPLink WR703N - you can get a USB/TTL device on ebay for about $2 that will then let you plug into the USB device on the TPLink and hook into the serialport of the Arduino - Arduino monitors for the button press and send a serial message to the TPlink which is listening and then sends an email
The TPlink can be configured as either a wired ethernet client or a wireless client or with a USB Hub can also address a USB GSM modem.
