3-Channel Off-Board AC Current Monitor for IoT
- Particle Electron Socket (IoT Motherboard)
- On-Board Processor Manages all Measurement Conversions
- Offboard sensors for ease of installation and versatility
- High Accuracy
Use your Particle Electronor Photon* or Bluz Bluetooth LE (Low Energy) to monitor energy with this 3-Channel high-accuracy current monitoring controller. Use our Particle library to communicate energy monitoring data to the Particle cloud or adapt our library for your specific application using the Arduino wire language.
This device includes three off-board current sensors, and an I2C cable. It provides an ideal energy monitoring solution for most industrial and commercial applications at a low cost with unmatched accuracy.
To use this device, simply run an AC power wire through the opening of the current sensor. This controller will read the magnetic field inducted onto the current sensor and provide you with a real-world current measurement value that is 98% accurate (prior to calibration).
This current monitoring controller includes our second generation firmware, which maintains best possible accuracy when measuring inductive loads, minimizing the need for calibration. This controller is pre-calibrated for resistive loads, but has demonstrated 98% accuracy when measuring most inductive load sources.

These boards include off-board split-core sensors that can be clamped around a wire for simple installation. They are each tuned for one of these specific amperages:
- 10 Amp
- 20 Amp
- 30 Amp
- 50 Amp
- 70 Amp
- 100 Amp
These devices are for AC Current Measurement Only. These controllers may not be used with ay other sensor. The sensor rating of this controller is 100 Amps; however, this controller is tuned to measure the selected amperage. It is not possible to measure current outside the tuned range of this controller. Never exceed 110% of the rated current range of this controller (selected amperage) or permanent damage to the controller may result. To achieve highest possible accuracy, each channel may require calibration for the type of load under measurement. As with all current sensors of this type, loads below 1 Amp (1% of the sensor rating) are known for significantly decreased accuracy (around 90% or less). To increase accuracy of low-current loads, consider doubling the readings by looping your AC load wire through the sensor a second time. This will effectively double all readings and provide greater low-end accuracy.
Excessively noisy loads may greatly affect accuracy, but our testing has shown 98% or better accuracy with most loads tested. This controller dedicates 1.3 seconds for measurement of each channel and cycles through all available channels continuously. We recommend querying this controller every 10 seconds for best results.
