🌐 Network-Ready for Smart Control Applications

With support for 32 digital input/output (I/O) channels, the PIC‑WEB32 delivers precise, low-latency relay control. Each I/O can function as a dry contact or pulse-enabled wet contact interface, making the unit adaptable for a wide range of automation and remote monitoring scenarios.

Equipped with two independent Ethernet ports (10/100 Mbps), the controller supports dual MAC and IP addresses, offering network redundancy or segmentation for mission-critical operations.

Whether for smart buildings, legacy equipment bridging, alarm management, or SCADA systems, the PIC‑WEB32 streamlines Ethernet-based I/O expansion across your facilities.

Overview of AquaSwitch

The AquaSwitch operates using solid-state electronic sensing technology, which is not affected by oil films or metal surfaces. This feature enhances its reliability in various installation scenarios. When water comes into contact with the sensor, it triggers a relay output that can activate alarms or pumps, ensuring immediate response to potential leaks.

Key Features

• No Moving Parts: The AquaSwitch is designed without mechanical components, reducing the risk of wear and tear and increasing longevity.
• Relay Output: It provides a dry contact switch output that can be easily integrated into existing alarm systems or control panels.
• Versatile Installation: The sensor can be mounted in various locations, such as in the water tray of an air conditioning unit or at specific heights to monitor water levels effectively.
• User-Friendly: The installation process is straightforward, making it accessible for both professional technicians and DIY enthusiasts.

Applications

The AquaSwitch is particularly effective in:

• Air Conditioning Units: It helps monitor condensation trays where water accumulation is common.
• Server Rooms: Given that air conditioning failures can lead to overheating and equipment damage, the AquaSwitch provides critical early warnings of leaks2.
• Industrial Settings: In environments with extensive piping and machinery, the sensor aids in maintaining operational integrity by detecting leaks before they escalate into larger issues.

Advantages

The AquaSwitch offers several benefits:

• Early Detection: By alerting users to leaks promptly, it helps mitigate damage and repair costs.
• Peace of Mind: Users can operate their systems with confidence, knowing that potential water issues are being monitored continuously.
• Cost-Effective Solution: The initial investment in an AquaSwitch can save significant amounts in potential repair costs due to water damage.

The REFCO AquaSwitch Aircon Water Leakage Sensor is a reliable and efficient solution for detecting water leaks in air conditioning systems. Its advanced technology and user-friendly design make it an essential tool for maintaining the integrity of HVAC systems across various applications.

The reason I am doing this page is because I find development work using SEGGER IDE is really painful. It is really not a fun IDE to work with. Maybe in future, it will be better. But for now, I have a project to do, and I cannot spending time on a lousy development environment, knowing how fast it would be using a good IDE platform.

It is fortunate enough that a kind soul had developed a “GNU ARM Eclipse plugin” for development of ARMS firmware, currently supprted and maintain by Liviu Ionescu. While SEGGER does not support this plugin, it is recommended by them for developer who refer to use a better development environment for their programming.
https://www.segger.com/products/debug-probes/j-link/technology/ides/eclipse/

The only disadvantage is that the developer would not be able to use the SEGGER debugging function. Being a developer, I seldom find the need to use a debugger, nor I understand how important a hardware debugger is. I don’t find it very useful so far, and managed to turn out many projects without using it. Perhaps there is a better purpose of using a debugger that I did not understand.

This is my attempt to setup Eclipse IDE for ARM Cortex firmware development work. I hope this works as it can increase my productivity tremendously. I really have a lot of blocks using SEGGER IDE, after working with many better other IDE products.

Setting Up Eclipse IDE for ARM Cortex Microcontroller development work.

1. Download and install the Eclipse IDE. (for C/C++ Developers)
2. Open the Eclipse program, go to the menu Help -> Eclipse Marketplace…
3. Search for “GNU MCU Eclipse” plugin, or go to this page
