    Evaluating the PSoC Device To evaluate the default project programmed on the CY3236A-PIRMOTION board. Ensure that the jumper (shunt) is not connected on J4. Power the board using the 12-V adapter at the power jack, J1. Stimulate the infrared sensor by moving your hand over as shown in Figure 3-1.

  • Page 16: Programming Specifications And Connections

    3.2.1 Programming Specifications and Connections When the MiniProg is connected, you can use PSoC Programmer to program the CY3236A-PIRMO- TION Evaluation kit. Plug in the USB cable into the MiniProg before attaching it to the ISSP header on the board. When using MiniProg, the LEDs blink at a variable rate to track connection status. The green LED near the USB connector turns on after MiniProg is plugged into the computer and is con- figured by the operating system.

  • Page 22 Hardware 2. Power supply and Regulator The kit can be powered by a 9 V to 12 V DC wall transformer with a positive tip barrel plug and 1 A current rating. The onboard regulator converts the input voltage to a regulated 5 V required by PSoC and other passive components.
  • Page 23 Hardware 4. PIR Sensor The CY3236A-PIRMOTION board consists of a Glolab's PIR325 PIR sensor. Humans, at normal body temperature, radiate infrared light waves at an approximate wavelength of 10 µm. A PIR sen- sor can detect this infrared radiation and convert it to an electric charge. This charge is buffered through a FET and can be converted to voltage variations using a load resistor.
  • Page 24 Hardware 6. Test Points The DAC Debug Test Point is used to view the output of the processed PIR signal. Connect a scope to the test point to view the sensor performance after the PSoC has filtered, amplified, and digitized the analog signal from the PIR sensor.
  • Page 25 Hardware 9. Relay and AC Terminal Block The on board really is a 12 V relay that is controlled by PSoC via a transistor as shown in the follow- ing circuit diagram. The normally open and common pins of Relay are connected to an AC terminal block This unit allows you to connect a small AC powered device (the device is controlled by the relay).

  • Page 27: Code Examples

    Code Examples All code examples are available on the CY3236A-PIRMOTION kit DVD or at this location: <Install_directory>:\Cypress\CY3236A-PIRMOTION\<version>\Firmware Project Description This code example demonstrates Cypress's PSoC device's ability to control a PIR sensor to imple- ment motion sensing applications such as automatic lighting controls, automatic door openers, secu- rity systems, kiosk wakeup, and activating wireless cameras.
  • Page 28 Code Examples Figure 5-1. PSoC Designer Analog and Digital User Module Placement The firmware uses an infinite loop during which the PIR signal, relay-on time, and the output voltage of the ambient light sensor are sampled. Activation of the relay and motion LEDs are then deter- mined by the values acquired from sampling.

  • Page 31: Ambient Light Sensing

    Code Examples The amount of time the relay is active can be changed. Adjust the relay ‘On’ time by turning the potentiometer, R7, so that the relay remains on for longer periods. To increase the relay ‘on’ time, turn the potentiometer counterclockwise. Turn it clockwise to decrease the ‘on’ time. Ambient Light Sensing Figure 5-3.
