PIR Infrared Motion Sensor (HC-SR501) (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)

Waterproof DS18B20 Digital temperature sensor Resistor (Waterproof DS18B20 temp)
Description:

This is a pre-wired and waterproofed version of the DS18B20 sensor.  Handy for when you need to measure something far away, or in wet  conditions. While the sensor is good up to 125°C the cable is jacketed  in PVC so we suggest keeping it under 100°C. Because they are digital,  you don't get any signal degradation even over long distances! These  1-wire digital temperature sensors are fairly precise (±0.5°C over much  of the range) and can give up to 12 bits of precision from the onboard  digital-to-analog converter. They work great with any microcontroller  using a single digital pin, and you can even connect multiple ones to  the same pin, each one has a unique 64-bit ID burned in at the factory  to differentiate them. Usable with 3.0-5.0V systems.

The only  downside is they use the Dallas 1-Wire protocol, which is somewhat  complex, and requires a bunch of code to parse out the communication. If  you want something really simple, and you have an analog input pin,  the TMP36 is trivial to get going.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.

Specifications:

Cable specs:

  • Stainless steel tube 6mm diameter by 30mm long
  • Cable is 36" long / 91cm, 4mm diameter
  • Contains DS18B20 temperature sensor
  • If  your sensor has four wires - Red connects to 3-5V, Black connects to  ground and White is data. The copper wire is soldered to the wire  shielding
  • If your sensor has three wires - Red connects to 3-5V, Blue/Black connects to ground and Yellow/White is data

DS18B20 Technical specs:

  • Usable temperature range: -55 to 125°C (-67°F to 257°F)
  • 9 to 12 bit selectable resolution
  • Uses 1-Wire interface- requires only one digital pin for communication
  • Unique 64 bit ID burned into chip
  • Multiple sensors can share one pin
  • ±0.5°C Accuracy from -10°C to 85°C
  • Temperature-limit alarm system
  • Query time is less than 750ms
  • Usable with 3.0V to 5.5V power/data
