ADC ADS1115 16-Bit breakout - 4 channel with programmable amplifier
Product information:
With an ADC (analog digital converter) you convert an analog signal into a digital signal that you can read with a microprocessor. For example, the voltage of a sensor or a battery voltage that you want to read.
The ADS1015 ADC has a resolution of 12bits which makes it possible to measure a voltage in millivolts. If a signal is very low you can increase it with the built-in amplifier (gain) (up to 16x) so that you can measure/read more accurately.
The ADS1015 is equipped with an I2C interface, which allows it to be connected to the microcontroller with only 2 wires. With this board you have 4 extra ADCs at your disposal! Ideal for use with, for example, an ESP8266 that only has 1 ADC of its own.
The I2C address is easily set by connecting the ADR pin to GND, VDD, SDA or SCL. The address is then as follows:
0x48 (1001000) ADR -> GND
0x49 (1001001) ADR -> VDD
0x4A (1001010) ADR -> SDA
0x4B (1001011) ADR -> SCL
