Wireless electrical energy sensor

The CMA wireless electrical energy sensor is a sensor for measuring electrical power and energy in DC circuits. The energy sensor has separate source and load connections to use both the voltage of a current source and the current at a load.
The source and load connections accommodate standard and safety 4mm plugs. The sensor comes with four cables with 4mm plugs on one end and alligator clips on the other.

The electrical energy sensor is equipped with a color OLED display that displays sensor information and measured values. This makes the sensor suitable for use as a standalone measuring instrument.
This wireless energy sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks, and mobile devices (Android and iOS).
Ideal sensor for measuring renewable energy sources in education.

All specifications of the sensor are described it its Product manual.

Suggested physics experiments:

• Investigate how different loads (e.g., resistors of various values, motors, or bulbs) affect power consumption
• Compare the energy output of a solar panel under different lighting conditions
• Use the sensor to monitor how the voltage, current, and energy output of a battery change as it powers a device over time
• If you have a small model wind turbine, measure how much electrical energy it generates at different wind speeds
• Use the sensor to measure the efficiency of simple circuits by calculating input vs. output energy
