Week 15

Title: Find LED display meter for voltage and current.

Objective:

1. To display to others how many voltage and current that piezoelectric produce.

Method:

1. Do the research in the internet.
2. Find the available type in the market.

Result:

LED Digital Volt / Amp Panel meter / Amp 10 A (Red & Blue)

Description:

Size: 48mm X 29mm X 22mm Range: DC3.2-30V ( Can Measure Power Supply Directly ) Display: 0.56 "LED digital tube Display color: red (Volt) & blue (Amp) Refresh rate: about 500mS / times Input: DC voltage Resolution: 1% +1 digit Power Supply: DC3.2 -30V Operating temperature: -10degree ~ 65 degree red cable DC+, black cable DC - Attention if the Voltage over 30V ,it maybe will burned.

Conclusion:

This meter can easily show how many current and voltage has been produce by piezoelectric and others can see easily.
