Planned devices for the XO.
Devices will be connected to special unit powered by SiLabs programmable CPU.
Here are some ideas for possible devices:
- Thermometer
- Voltmeter, ampermeter, ohmmeter
- Oscilloscope
- Photodiode
- PH meter
- TeleHealth Module
- See also the Digital Signal Processing page for work being done in India
Processor unit
processor type: C8051F321 - Full Speed USB, 16k ISP FLASH MCU Family - ETC CPU specification
cpu size: 6mm x 6mm
board size: 15mm x 30mm
case size: 20mm x 40mm (size similar to USB Bluetooth adapter )
Calculated price:
CPU unit: cca 3$
board + additional electronic parts: 17$
connectors: 2$
Total price: 25$ (retail price)
Sensors
Sensors will be connected to the CPU unit. The CPU unit will measure values from the sensors and feed them into application on the XO. (CPU can use every sensor that can convert measurement into voltage or current)
Planned sensors:
- Thermometer (cca 2$)
- Voltmeter, ampermeter, ohmmeter, oscilloscope (cca 1$)
- Photodiode (cca 2$)
- PH meter
(if you find cheap sensors please add them into this list)
