Description
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 easily use a variety of analog Arduino series sensors to measure various signals. Perceive this world.
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.
Ocean: ADS1115 16-bit AD conversion module is optimized for Raspberry Pi and Arduino series analog sensors, which greatly reduces the difficulty of using Arduino series analog sensors on the Raspberry Pi main control board. It is plug and play, no soldering, and very convenient. . The Arduino series of sensors are numerous and rich in types, which can meet the needs of the Raspberry Pi main control board for various sensors.
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 .
