FAQ
Why is the test data wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)
Here we only talk about Active Power, for others, please google it:
P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P<U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.

Non-Contact Voltage Detector, 90-1000VAC (non contact voltage detector)
Description:
Everyone need a test pen to make sure if the line is clear from high voltage electricity, especially when you are working with AC (Alternating Current) line. This is alternative to test pen where it can detect AC voltage without touching the wire/contact itself :) And Yes! It works.
Get it near to your AC wire or plug (few millimeter) and if there is AC voltage, the LED will start to blink and the on board buzzer will also buzz. And there LED (another LED) activation push button if you need eatra helping light when you work :)
It is powered by 2 x AAA (1.5V) battery, not included in the package.

DC Voltage detection Sensor (DC Volt sensor)
Description
This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, Arduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because Arduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.
