Data Harvest Wireless voltage and current sensor

This sensor is simultaneously a sensor for voltage and current combined in one package.

It can be used to measure both the electrical current and the potential difference in a component in low voltage AC or DC circuits.

The voltage sensor measures the difference in potential between two points in a chain in a range between -20 V to +20 V.

The current sensor measures the current running in a circuit in a range of -1 A to +1 A (± 1000 mA).

Use 4 mm plug wires (not included in the kit) to connect to most standard available electronic sets and school supplies.

Here are just a few examples of practical ideas that you can achieve using the wireless 20V voltage and current sensor:
       - A point in the chains, (Kirkhoff's law);
       - Sequencing and parallel circuits;
       - Om's law;
       -Quality and poor wires;
       -Savers;
       - Lamp tone;
       -Haracteristics of electrical components;
       -Dynamo effect;
       -Induction of Faraday to current or voltage in winding;
       -Dilution of capacitor, charge and stored energy;
       -Diodes and diode vaporization;
       -Change the impedance with frequency;
       -Engine efficiency;
       -Resonance in a consistent LCR chain;
       -Reactive resistance and phase in capacitor.
