I am making a device that consists of the following 2 parts.
The size of each part should not exceed that what you can hold in a hand.
Part 1
1. Continuously samples voltages from a potentiometer.
2. Wirelessly transmits the samples.
- a sample is 1 or 2 bytes.
- a sample sent 5 times per second is sufficient.
- the distance is about 25 cm (constantly changing).
Part 2
3. Receives samples from Part 1.
- samples are logged.
4. Has an additional 1 bit digital input that goes high once in a while.
- the rate is logged.
5. Does some minor calculations on the received data.
6. Displays the data on a small screen in real-time.
My question:
Which technology would you recommend for the wireless datatransfer between the two parts?
Any idea is welcome.
