WattTap<\/h1><\/span><\/a><\/div>\n

This project creates a connected Wattmeter using a TapNLink module. The project uses TapNLink's embedded Java Virtual Machine (JVM) as the application processor. The JVM runs a simple Java program retrieves power consumption data from the Wattmeter.<\/p>\n

*** WARNING ***<\/h2><\/span><\/a><\/div>\n

THE WATTMETER IN THIS DESIGN CONNECTS DIRECTLY TO 220 VOLT MAINS POWER.<\/p> \n

Physical contact with any component of the design can cause electrocution resulting in serious INJURY, or DEATH.<\/p> \n

DO NOT reproduce this design without appropriate knowledge of, and protective measures for working with mains power.<\/p>\n

Disconnect power before handling the material or manipulating the connections. Ensure that material is properly grounded and isolated. Always work with another adult present in case of an emergency.<\/p>\n

*** DISCLAIMER ***<\/h2><\/span><\/a><\/div>\n

This electrical project is provided ONLY for testing and experimentation by qualified persons in electronics design labs.<\/p>\n

The person reproducing this example accepts full responsibility to any injury, or damage that may result.<\/p>\n

This example is not a product. This example is not Certified, Qualified, Approved, or Recommended for any commercial use, or for any use by the general public.<\/p>\n
