Analog 50A current sensor (AC / DC)

Analog 50A current sensor (AC / DC)

It is possible to monitor the current of the project every second for energy saving and circuit protection.

This product is a breakout board for the fully integrated Hall effect-based linear ACS758 current sensor. It provides accurate current measurements for both AC and DC signals, and the thickness of the copper conductors allows the device to survive in high overcurrent conditions. The ACS758 outputs an analog voltage signal that varies linearly with the detected current. 【Features】 ■ Arduino interface compatible ■ Standard bandwidth of 120 kHz ■ 3μs output rise time in response to step input current ■ Output voltage proportional to AC or DC current ■ Factory calibrated for accuracy, etc. *For more details, please refer to the external link or feel free to contact us.

Analog AC current sensor

Analog AC current sensor

For measuring AC current in AC motors, lighting fixtures, air compressors, etc.

This product is a sensor used for measuring AC current. When you want to measure AC current, cutting the actual wiring can be dangerous, but the analog AC current sensor developed by DFRobot solves this problem. Place the AC wire inside the unit, use a 3.5mm jack connector to connect the unit to the sensor board, and then connect the sensor board to the analog input of the microcontroller. This sensor can be used to measure AC motors, lighting fixtures, air compressors, or other devices that use AC current. 【Features】 ■ Measurement possible without cutting the wiring ■ Supports Gravity 3-pin interface ■ Analog output *For more details, please refer to the external link or feel free to contact us.

Energy conservation, decarbonization, electricity cost reduction CS-VP chaos map/industry map

Energy conservation, decarbonization, electricity cost reduction CS-VP chaos map/industry map

This chaos map is an industry map classified along two axes: the vertical axis represents customers and the horizontal axis represents the value provided.

"Energy Coloring" has conducted research and analysis on energy-saving, decarbonization, and electricity cost reduction services in the power industry through hearings with industry stakeholders since its establishment in 2019. In the classification process, we focused on unique features compared to other companies based on information available on the internet, or classified them based on their core business. A typical chaos map classifies companies and services based on the similarity of the services offered and groups them together. However, during the analysis of services in the power industry, we found many instances of "companies with the same VP but different CS" and "companies with the same CS but not in competition with each other." It became clear that simply using similarity would group together companies that are not essentially in the same category, leading to a lack of clarity. The CS-VP chaos map allows us to group competing companies together, making it possible to list players by business model within the power industry.
