## Pricing

- **Price:** $21.35 (inc GST) — $19.41 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 5 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR1184:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR1184:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The Gravity: 0-10V 15-Bit High-Precision ADC Module combines **dual-channel 0-10V input with I2C and UART interfaces**, offering unmatched flexibility for [Arduino](https://core-electronics.com.au/arduino.html), [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html), and [ESP32](https://core-electronics.com.au/development-boards/esp32.html) users. Featuring **15-bit resolution (0.3125mV accuracy**) and the Texas Instruments ADS1115 chip, it bridges industrial 0-10V sensors (e.g., pressure transducers, energy meters) with low-voltage microcontrollers. Perfect for automation, environmental monitoring, and IoT systems requiring stable, noise-resistant signal conversion.

**Industrial-Grade 0-10V Sensor Compatibility**

The module directly interfaces with industrial-standard 0-10V sensors, such as pressure transducers, flow meters, and wind speed sensors. It resolves the voltage mismatch between high-output sensors (0-10V) and low-voltage microcontrollers (e.g., [Arduino](https://core-electronics.com.au/arduino.html), [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html)), eliminating the need for external signal conditioning.

**15-bit Resolution with Enhanced Accuracy**

With a 15-bit ADC and ±2mV precision, the module captures subtle signal variations (e.g., 0.3125mV steps), making it suitable for applications requiring fine-grained data, such as water tank pressure monitoring or energy consumption analysis. The ADS1115’s PGA dynamically adjusts gain to maintain accuracy across the full 0-10V range.

**Flexible Communication Interfaces**

Dual I2C and UART protocols ensure compatibility with diverse controllers, from Arduino boards to industrial PLCs. The Gravity-4P connector standardizes wiring, reducing setup complexity for multi-sensor systems.
