IR - Infrared Receiver (TSOP38238) (TSOP 38238 infrared receiver)

IR (Infrared) sensor tuned to 38KHz, perfect for receiving commands  from a TV remote control. Runs at 3V to 5V so it's great for use on the  Raspberry Pi!

To use, connect pin 3 (all the way to the right) to  5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do  any decoding of the signal, just passes the 'raw data' along.

Specifications

  • Carrier Frequency: 38kHz
  • Transmission Range: 45m
  • Directivity: 45°
  • Supply Voltage Min: 2.5V
  • Supply Voltage Max: 5.5V
  • Supply Current: 350µA
  • Opto Case Style: Through Hole
  • Operating Temperature Min: -25°C
  • Operating Temperature Max: 85°C
  • Packaging: Each
  • Operating Temperature Range: -25°C to 85°C
  • SVHC: No SVHC (16-Dec-2013)
  • Supply Voltage Range: 2.5V to 5.5V

IR Receiver Diode VS1838B - 38KHZ (VS1838B infrared receiver)


IR sensor with filter at 38KHz, perfect for receiving commands from a TV remote control. Runs from 2.7V to 5.5VDC so it's great for any microcontroller, which include Arduino running at 3.3V or 5.0V, and of course include Raspberry Pi which run at 3.3V.

To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do any decoding of the signal, just passes the 'raw data' along. Check the VS1838B datasheet for more details.

Features

  • IR Remote Control Receiver
  • Built-in Filter at 38KHz
  • Wide operating voltage range: 2.7V to 5.5VDC

Adafruit ADS1015 12-Bit ADC (ADS1015 12-Bit ADC)
The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet and interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5 in downloads below) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs. 
 
To get you started, we have example code for the Raspberry Pi - Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
 
The Adafruit 4-Channel I2C 12-Bit ADC Features:
  • Wide Supply Range: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Programmable Data Rate: 128SPS to 3.3kSPS
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA
  • I2C Interface: Pin-Selectable Addresses
  • Can run from 2V to 5V power/logic
  • Measures a large range of signals and is super easy to use.
  • 12-bit precision at 3300 samples/second over I2C.
  • Configurable as 4 single-ended input channels, or two differential channels.
  • Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
  • Breakout Board equipped with ferrites to keep the AVDD and AGND quiet
