5. Adafruit ADS1115 16-Bit ADC 4 Ch. w/Gain Amplifier
For microcontrollers without an analog-to-digital converter or when
you want a higher-precision ADC, the ADS1115 provides 16-bit precision
at 860 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, up to x16, to
help boost up 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 16 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites
to keep the AVDD and AGND quiet. Interfacing is done via I2C. The
address can be changed to one of four options (see the datasheet table
5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C
bus for 16 single ended inputs.
To get you started, we have example code for both the Raspberry Pi
(in our Adafruit Pi Python library [1]) and Arduino (in our ADS1X15
Arduino library repository [2]) 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.
* Wide Supply Range: 2.0V to 5.5V
* Low Current consumption: Continuous Mode: Only 150A Single-Shot
Mode: Auto Shut-Down
* Programmable Data Rate: 8SPS to 860SPS
* Internal Low-Drift Voltage Reference
* Internal Oscillator
* Internal PGA
* I2C Interface: Pin-Selectable Addresses
* Four Single-Ended or two differential Inputs
* Programmable Comparator

6. Adafruit Magnet sensor
This door sensor is a reed switch made of ABS plastic. Normally, the reed is open (no connection between the two terminals). The other half is a magnet. As soon as the magnet is less than 13 mm away from the switch, the switch closes (connection between the two terminals). These sensors are mostly used to determine whether a door or drawer is open or closed. Therefore, both parts of the sensor have mounting holes, and 4 screws are included in the package.
