PIR Infrared Motion Sensor (HC-SR501) (2B3 pir sensor big)

Description:

PIR sensors, often referred to as, "Passive Infrared" or "IR motion"  sensors, enable you to sense motion. Everything emits a small amount of  infrared radiation (IR), and the hotter something is, the more radiation  it emits. PIR sensors are able to detect a change in average IR levels  of their detection zone (e.g. when a human enters a room, that room will  increase in temperature slightly) and hence sense motion. 

This  one's great, as it can be powered  via the Raspberry Pi's 5V output, and  be read directly from the Raspberry Pi's GPIO input (as the sensor has a  digital 3.3V output!)

This PIR includes an adjustable delay  before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and  two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing  the regulator with a bit of soldering) and has a digital signal output   (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100  degree cone.

Specifications:

  • Input Voltage: 4.5V - 20V
  • Current Draw: <50µA
  • Digital Output: 3.3V (High)
  • Digital Output: 0V (Low)
  • Working Temperature: -15°C to 70°C
  • Delay Time: 0.5 - 200 Seconds
  • Sensing Angle: 100° Cone
  • Range 5m - 7m

 

Dimensions:

  • Sensor Lens Diameter: 23mm
  • Length: 24.03mm
  • Width: 32.34mm
  • Height (with lens): 24.66mm
  • Centre screw hole distance: 28mm
  • Screw hole diameter: 2mm (M2)

SparkFun Logic Level Converter Bi-Directional (3A4 Sparkfun logic level converter )

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.

This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.
