Smart Energy Management: Programmable ESP32 MODBUS/Wi-Fi Meter for Arduino/Atmel studio
AU$170.00
Product Specification: SM Energy FE102M Energy Monitor
Key Features:
Core Components:
ESP32 WROOM 32: Equipped with wireless and Bluetooth capabilities.
ATM90E26 Energy Monitor: Fully compliant with IEC62052-11, IEC62053-21, and IEC62053-23 standards.
Metering Features:
Interrupts: Integrated with ESP32 for Active Energy pulse, Reactive Energy pulse, WarnOut fault, and Voltage/Current Zero Crossing interrupts.
Accuracy: ±0.1% for active energy and ±0.2% for reactive energy over a dynamic range of 6000:1.
Temperature Coefficient: 6 ppm/℃ (typical) for on-chip reference voltage, with automatic temperature compensation.
Calibration: Single-point calibration for active energy across the entire dynamic range; no calibration required for reactive/apparent energy.
Non-linearity Compensation: Features three current (RMS value)-based segments with two programmable thresholds per phase, along with independent gain and phase angle compensation.
Electrical Parameters Measurement:
Less than ±0.5% fiducial error for Vrms, Irms, mean active/reactive/apparent power, frequency, power factor, and phase angle.
Energy Registers: Independent registers for Active (forward/reverse), Reactive (forward/reverse), and Apparent energy.
Programmable Thresholds: Configurable startup and no-load power thresholds.
Additional Features:
EEPROM: 24C256 (I2C).
LCD Module: I2C 20X4.
