We are interested in designing, and prototyping and printing a compact embedded system which will comprise of a small hardware unit with the following tasks:
SCENARIO A (with button)
1.A device comes with a button.
2.The device also includes a cell phone sim card.
3. When the button is pressed, an SMS message will be transmitted. Optionally a REST API call to a remote server over WiFi or a Bluetooth signal.
SCENARIO B (with motion sensor)
Same as scenario A, utilizing a motion sensor as a trigger.
The ideal unit diameter would be 2~3 cm yet there are physical limitations for designs over 5-8 cm diameter.
You may provide similar work samples and related experience in your response.
Please provide an abstract hardware cost estimation (prototype/mass production).
Please provide further information on the design process you are familiar with (PCB design software, microcontroller of choice, design process, prototyping, testing, etc).
An estimation of project delivery time is also required.
Please apply responsively.
