Wireless Smart Control Valve: Enhancing Automation with nRF52832

Introduction

Smart control valves, critical IoT components, are widely used in automation, smart homes, and industrial control. This solution, based on the nRF52832 SoC, leverages Bluetooth Low Energy (BLE) for efficient, reliable wireless control and data transmission, optimizing fluid management.

01. Solution Overview

The wireless smart control valve is a lithium-thionyl chloride battery-powered, high-reliability device with 4G/NB-IoT/BLE communication. It features dual sensor interfaces (default temperature sensor for return water), a segment display showing temperature, valve position, fault codes, battery level, signal strength, and communication status. The valve auto-rotates periodically to prevent scaling, uses UV indicators for mechanical valve position, has a high IP rating, a hidden power switch, and one-button restart for instant data reporting.

02. Working Principle

The smart control valve integrates sensors, a control module, and an actuator for precise fluid control. Sensors monitor pressure, temperature, and flow, sending data to the control module. If parameters deviate, the module instructs the actuator to adjust the valve opening, maintaining optimal flow. Connected via BLE or Wi-Fi, it enables remote control and data monitoring, enhancing automation.

03. Recommended Chip

The nRF52832 multi-protocol SoC provides low-power, stable, long-range BLE connectivity, eliminating range and stability issues. It enables wireless control, remote data collection, and valve status monitoring via a smartphone app. With low latency and integration with smart home systems, it ensures efficient fluid management.
