Simply install this module on the target device to utilize it as a current sensor module!

The FN-CPT-BMEMD is a module that transmits data from connected sensors without using batteries or commercial power sources. It generates its own driving power from very small alternating current sources, such as magnetic fields generated by cables and vibration energy harvesting, and sends sensing data via Bluetooth to higher-level systems. Therefore, by simply attaching this module to the target device, it can be utilized as a current sensor module. Additionally, by clipping to a power source, it can harvest weak direct current power, enabling it to supply power to IoT devices and sensors that operate with low power consumption.

Applications/Examples of results

The FN-CPT-BLEMD is a module that transmits sensing data in various ways without using a battery (*). * The power supply for this module operates on "very small alternating current" from leakage current from cables, vibration generation, etc. Application Example 1 Clip this module onto the power lines of various electrical devices such as air conditioners and refrigerators. The measured current values are transmitted via Bluetooth to smartphones or Bluetooth gateways, and then sent to higher-level systems. Servers or smartphone applications can verify the transmitted data, allowing for early detection of device failures based on the trends in current values. By increasing the number of connected current sensors, high-precision sensing and data transmission can be achieved. Application Example 2 By clipping onto the power line, it is possible to draw weak direct current through this module. This enables power supply to IoT devices and sensors that can operate with low power. * The 3.3V current varies depending on the number of sensors and the consumption current of the clipped devices.
