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

IQaudIO DigiAMP (IQaudio Digi Amp )

Description:

DigiAMP is a HAT compliant add on accessory for the Raspberry Pi. DigiAMP uses the Texas Instruments TAS5756M PowerDAC to deliver direct connection to PASSIVE stereo speakers at up to 2x35wpc with variable output. Ideal for a Pi based HiFi. DigiAMP can be connected to the Raspberry Pi A /B /RPi2/RPi3 or RPi4's 40way pin header without any additional soldering. DigiAMP must be powered from an external supply and requires a 1 2 to 24DC power source to
operate. DigiAMP s barrel connector is 5.5mmx2.5mm. DigiAMP has been designed to provide power to the Raspberry Pi and DigiAMP combination in parallel, delivering 5.1v 2.5Amp to the Pi.

DO NOT APPLY POWER TO THE RASPBERRY PI’s OWN POWER INPUT WHEN USING DIGIAMP .

The amplifier is by default muted at power on (mute LED lit). The mute state LED is under software
control (Raspberry Pi GPIO22).

Four Digit - Seven Segment Display - Red (display 7 segment red)
Description:

This lovely little (14.2mm) seven segment display provides excellent segment uniformity and is highly visible up to seven meters away. It's ultra bright, and provides great readability even in bright ambient light!

It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.

These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.

This is an ultra bright RED colour.

Specifications

  • 100mcd
  • 14.2mm (0.56") digit height
  • Color: red (630nm)
  • Common cathode display
  • Maximum power dissipation per segment: 66mW
  • Maximum pulse peak forward current per segment (1/10th duty cycle, 0.1ms pulse width): 100mA
  • Maximum forward current per segment: 20mA
  • Maximum reverse voltage: 5V
  • Maximum reverse current: 20µA
  • Typical forward voltage: 2.1V at 20mA
  • Maximum forward voltage: 2.5V at 20mA
  • Operating temperature range: -30°C - 70°C
