DIYmall ADS1115 I2C Pi ADC Analog to Digital Converter Board for Raspberry Pi (Pack of 2pcs) FZ3887X2
The Raspberry Pi is an excellent small board computer that you can use
to control digital inputs & outputs. However what do you do when
you want to read an analog signal, like what you might get from a
thermistor, potentiometer, or many other types of sensors? Don't give
up! By connecting a small analog to digital converter (ADC) chip to the
Pi you can open up the world of analog signals to your Raspberry Pi
So we designed a ADS1115 Pi ADC module to helper you read the analog signal. 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. It is a great general purpose 16 bit converter.
Works perfectly with any Raspberry Pi including the Pi 1, Pi 2, Pi 3, Pi Zero, A+, B+ etc.
Programmable data rate: 8SPS to 860SPS
