Raspberry Pi is a common main control board with powerful functions; However, the pins of the Raspberry Pi main control board can only read digital signals; If you need to read the signals of analog sensors or devices, you can only connect an analog-to-digital conversion ADC module, which is not convenient to use; The ADS1115 16-bit AD conversion module can accurately collect and convert analog signals;
Through this AD module, the Raspberry Pi main control board can be very conveniently compatible with the Arduino series of analog sensors, measure various signals, and perceive this world; ADS1115 16-bit AD conversion module is specially designed for Raspberry Pi compatible with Arduino series analog sensors, which greatly reduces the difficulty of Raspberry Pi main control board compatible with Arduino series analog sensors, plug and play, no soldering, very convenient; This module uses the 16-bit ADC chip ADS1115, which supports a wide voltage supply from 3.3V to 5V; The chip has a precision reference voltage and programmable gain adjustment PGA, so it can be used for weak signals or signals with large changes;
Accurate acquisition and conversion, so this module is also suitable for all kinds of occasions where the main control board needs to accurately collect analog signals; One AD module can read 4 channels of analog signals; Due to the onboard I2C address selection switch, it supports the cascade of 2 AD modules and reads 8 channels of analog signals, which is sufficient to meet the needs of various scenarios.
