Portable Measurement Setup

Benefits

• Multiple options for connecting with VPN capabilities
• Can use existing hardware designed for mains voltage
• Easy to transport
• Provides stability where mains supply is not reliable
• Made of off-the-shelf parts

Drawbacks

• Battery life limited, not suitable for difficult to get to environments or very remote locations
• Enormous size

System diagram

• Make sure that any equipment connected directly to the battery is rated for maximum battery charger voltage (>15 VDC)
• Use a relay if you need to disconnect multiple devices using a pushbutton (charger and load), since all connected devices tend to draw current even while idle

What's inside

Applications

Configure the router so that it extends your logging network or LAN to the remote location.

Battery life will be limited, as typically routers and any equipment designed to be used from mains are not optimized for power consumption.

• Back up power for unreliable mains supply in measurement setups
• Environmental (Temperature, Humidity, Pressure, Acoustic noise level) measurements during a specific event
• Power line measurements
• Transportation measurements
