ModMyPi - Pi PIR Motion Sensor Camera Box Bundle - B+/2/3/3B+ (C4 Pi 3 cam case pir)

RASPBERRY PI AND CAMERA NOT INCLUDED

A new PIR Motion Sensor modified version of our popular Raspberry Pi Camera Box! This bundle includes a specially designed black matte  Pi Camera Box Case, a Magnetic Fish-Eye Lens, Camera Box Wall Mount and an HC-SR501 PIR Motion Sensor.

Compatible with both the original V1 and V2 Raspberry Pi camera modules and compatible with the Raspberry Pi 3B+!

The flexibility of this design is ideal for using a Raspberry Pi and its camera module in a variety of applications such as security with a wide angle fish-eye lens, process monitoring, computer vision, high-definition time lapses, motion sensing and many other fun projects.

Pi PiR Camera Box Case

The 'ModMyPi Pi Camera Box' is designed for hosting a Raspberry Pi computer and a Pi Camera module together in a compact and versatile enclosure. This all-integrated design ensures that the camera's fragile ribbon cable doesn't get damaged while exposed during operation. This case can accommodate an optional magnetic camera lens, which opens up new possibilities above and beyond the outstanding optical quality of the Pi Camera module. The black matte case is opaque, ensuring that the red led mounted on the Pi Camera module will not affect the ambient light captured by the camera. The back of the 'Pi Camera Box' can accept an optional wall-mounting bracket for permanent installations. This special edition features an HC-SR501 PIR Motion Sensor so it's great for security or recording animal nightlife!

Features:
  • Includes an HC-SR501 PIR Motion Sensor and jumper cables for connection & mounting
  • Black matte acrylic
  • Assembly time: about 10 minutes
  • Access to all of Pi's connectors
  • Features vents on the bottom, top, left and right walls
  • Features a slot for a GPIO ribbon cable
  • Dimensions: 101mm x 70mm x 33.3mm
  • 3mm thick black acrylic case (7 pieces, including left walls for both models A and B)
  • 4x rubber feet

Camera Box Wall Mount

The Raspberry Pi Camera, enclosed with the Pi in the Camera Box, and equipped with a fish eye lens, is a very capable surveillance and monitoring system that is easy to connect and program. To make the most of it, the Pi Camera box should be steadily mounted to a wall or a ceiling and should be properly angled. This bracket allows tilting and swiveling of the device. Just tighten the thumb screws when you have found the right position and you're done.

Features:

  • Bracket max. weight: up to 3.5kg (7.7 lbs)
  • Wall / ceiling mounting screws
  • Tilt angle: -24° to +15°
  • Swivel angle: ~75° left and right
  • Thumb screws for easy angle adjustments

Magnetic Fish-Eye Lens

The Raspberry Pi's camera offers great features out-of-the box, which can be enhanced by adding interchangeable lenses. The fish-eye lens will give your Raspberry Pi camera a panoramic view of its surroundings, making it perfect for surveillance, security and general monitoring scenarios. The Pi Camera Box is designed to receive the small metal ring needed for binding the magnetized fish-eye lens to the case.

Features:

  • Magnetic fish-eye lens
  • 180 degree angle (see note below)
  • Self-adhesive metal ring mount
  • Plastic lens cap
  • Key-chain attachment

Waterproof DS18B20 Digital temperature sensor + Resistor (2B3 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

Contents:

  • 1 x DS18B20 Digital temperature sensor
  • 1 x 4.7k resistor
