Waterproof DS18B20 Digital temperature sensor + Resistor 1M (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.

PUD Board (Pull-Up/Down Resistor Board) (MMP PUD board)

RASPBERRY PI BOARD NOT INCLUDED

Whether you're pulling-up or pulling-down, there's no need to frown! With the PUD board from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy!

If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!

Like our gate, the best way to avoid a floating input is to "tie" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.

Our PUD board takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD board and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I/O's!

The PUD boards connects across GPIO pins 11 to 18 (17 to 24 in BCM speak), and adds a jumper configurable pull-up or pull-down resistor to each GPIO pin: 11 (BCM 17), 12 (BCM 18), 13 (BCM 27), 15 (BCM 22), 16 (BCM 23) and 18 (BCM 24). Pin 17 (3.3V) & pin 14 (GND) are used to tie the pins!

The PUD Board Features:

  • Add a pull-up or pull-down resistor to your GPIO with the swap of a jumper!
  • Compatible with all Raspberry Pi Models Inc. A+/B+/2/3 & Zero/ZeroW
  • Tiny board means it's easy to integrate into any circuit - takes up just 8 GPIO pins
  • Connects across GPIO pins 11 to 18 inclusive (BCM 17 to 24)
  • In-line 1kΩ current limiting resistors on each GPIO
  • 10kΩ pull-up or pull-down resistors on each GPIO
  • All 6 GPIO pins can be configured independently 
  • Includes 6 x 2 Pin Shunt Jumpers & 1 x PUD Board
  • Jumper configurable pull-up or pull-down resistor on pins:
    • 11 (BCM 17)
    • 12 (BCM 18)
    • 13 (BCM 27)
    • 15 (BCM 22)
    • 16 (BCM 23)
    • 18 (BCM 24).
  • Pin 17 (3.3V) & Pin 14 (GND) are used to tie the pins!
  • To pull pin up, connect the jumper across "u" and the center pin
  • To pull pin down, connect the jumper across "d" and the center pin
