The ADS1115 ADC Module solves this by reading analog signals from sensors or components and converting them into digital data your Raspberry Pi can process. It connects via the I2C interface using just two GPIO pins, making it a simple and essential add-on for any project that involves analog sensors.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the ADS1115 Module easy to set up with Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — setup is straightforward. The module communicates over I2C, which is supported natively by Raspberry Pi 3, 2, and B+. Simply connect VCC to 3.3V, GND to ground, and the SDA\/SCL pins to the corresponding GPIO pins. Several open-source Python libraries are available to help you start reading data quickly.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I connect multiple ADS1115 modules to the same Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The ADS1115 supports 4 selectable I2C addresses, allowing you to connect up to four modules simultaneously on the same I2C bus. This is ideal for projects that require monitoring many analog inputs at once.\u003c\/p\u003e\n\u003ch4\u003eQ: What types of sensors can I connect to this ADC module?\u003c\/h4\u003e\n\u003cp\u003eA: You can connect a wide variety of analog sensors, including temperature sensors (e.g. thermistors, LM35), light sensors (e.g. LDR\/photoresistors), soil moisture sensors, potentiometers, current sensors, and more. With 4 input channels and a programmable gain amplifier, it handles both high and low voltage analog signals.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
