Il sensore capacitivo ed il refrigeratore d’acqua
Mai più guasto il distributore automatico di acqua minerale
Pubblicato in Numero 4, Febbraio 2009
Lo scopo di questo articolo è quello di illustrare non solo come si possono realizzare apparecchiature più affi dabili grazie ai sensori capacitivi, ma anche come il controllo di questi dispositivi può signifi care un incremento delle funzioni aumentando il valore aggiunto verso i clienti, e riducendo allo stesso tempo i costi di manutenzione. Per mettere in pratica tutto ciò, Elektor vi offre due kit di valutazione CapSense.

Reader Offer: CapSense Touch Sensing Buttons and CapSense Touch-Sensing Sliders development kits
Capsense evaluation kits
By special arrangement with Cypress, Elektor offers two entry-level CapSense Express development kits to enable readers to get acquainted with capacitive sensing technology in a time efficient way. You can buy one or both at a special price from the Kits & Modules section of the Elektor Shop (www.elektor.com/shop), or phoning customer services, of course.
CY3218-CAPEXP1 Evaluation kit (Elektor Shop # 080875-91)
This kit is for learning about touch sensing buttons. The PSoC device used on the evaluation board has up to 10 I/Os for buttons, LEDs and general-purpose I/O devices. The kit contains the CY3218-CAPEXP1 evaluation board, a retractable USB mini cable (A to mini B), a PSoC CY3240-I2 bridge board and an AA battery. Also included is the kit CD which contains PsOC programmer, .NET Framework 2.0, PSoC Express 3, CapSense Express Extension Pack and the CapSense Express documentation.
CY3218-CAPEXP2 Evaluation kit (Elektor Shop # 080875-92)
This kit teaches you implement capacitive sensing slider devices in electronic equipment. Contents as CY3218-CAPEXP2, except CY3218-CAPEXP2 evaluation board included in this kit.
Both kits represent excellent educational value for all of you wishing to eradicate, once and for all, the weaknesses and failures of mechanical switches and slider pots traditionally fitted on consumer equipment that gets a bashing, like the pitiable soda vending machine in the roadside motel!
The manuals included in the kits concentrate not just on running the evaluation boards ‘as is’ but also cover developing your own capacitive sensing applications, combining hardware with software. With these boards you’ll have a good time exploring the concepts of PSoC, programming, compiling, debugging, driver configuring and adapting the examples provided to meet your own requirements. The little CY3240-I2 bridge board in the kits is also valuable for entry-level dealings with other Cypress PSoC products. If ever there was a chance to get into PSoC and cap sense at a sensible price, it’s right now.
