ADS1015 CJMCU Digital-Analogic Converter Module ( ADC)
This module is ideal for microprocessors that do not have an analogue-to-digital converter, or when you need a high precision converter. The ADS1015 chip provides 12-bit precision, 3300 samples / second through I2C. Another bonus of this converter is that it works between 2V and 5V, and can measure a wide range of signals, making it very easy to use.
