توضیحات
ماژول آنالوگ به ديجيتال ADS1115 ، داراي رزولوشن 16 بيتي است . ديتا از طريق رابط I2C ارسال مي شود که چهار آدرس اسليو I2C مي تواند انتخاب شود. تغذيه اين ماژول را ولتاژ 3.3 ولتي تامين مي نمايد. از اين ماژول براي تشخيص سيگنال آنالوگ و تبديل آن به سيگنال ديجيتالي استفاده مي شود. با استفاده از اين ماژول به آساني جوي استيک و يا سنسورهاي آنالوگ نظير NTC و ... را به برد رسپبري پاي خود متصل نماييد .
Description
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 chips 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 ADS1115s 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), Arduino (in our ADS1X15 Arduino library repository) and CircuitPython. Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontrollers I2C port and run the example code to start reading data.
