IR Door Minder
 
This kit uses an infrared (IR) beam to monitor door & passage-ways or any other area. When the beam is broken a relay is tripped which can be used to sound a bell or alarm. Suitable for detecting customers entering a shop, cars coming up a driveway, etc. The IR beam is very strong. Distances over 25 yards can be monitored with this kit. A 12VDC unregulated supply is required to power the kit. A 12V wall adaptor is fine. Only one power supply needs to be used to power both units. The relays in this kit are rated to switch mains voltages. With power applied the relay is normally operated and only releases when the beam is broken. The relay contacts labelled “NO” (Normally Open) and “NC” (Normally Closed) refer to when the relay is released. The plastic tube is to put over the IR LED to direct its beam. This is needed when the barrier is only a few yards apart. IR transmitter PCB size:: 45mm x 30mm (1.77" x 1.18")
IR receiver PCB size:: 50mm x 48mm (1.97" x 1.89") (CPS130)

Negative or Positive ION generator
 
Mains powered ion generator which may be made into a negative or positive ion generator depending on the orientation of the 30 diodes. A neon light indicates whether the kit is on or off. The kit must be built into a box for routine operation. The use of this circuit will greatly benefit your health and will give you a feeling of comfort. It helps clean the air from dust, pollen, smoke and pollution. The increased concentration of negative ions in the air makes it feel fresher, brings a feeling of well being, helps in reducing stress and effectively reduces the severity of symptoms in some respiratory troubles. PCB size: 108mm x 50mm. (4.25"x1.97")
Supply voltage: 120 VAC (CPS57)

USB EXPERIMENT INTERFACE BOARD
 
The K8055 interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (98SE, 2000, Me, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. (K8055)
