HVAC humidity sensor

Motor control system solution

The RL78/G14 microcontroller and HS300x sensor provides a motor control system solution with relative humidity/temperature measurement for predictive failure diagnostics. The solution also supports appliance safety standard IEC/UL 60730, and supports closed-loop feedback with relative/humidity temperature for recirculation of outdoor to indoor air. Power and timing solutions are also available to complete these solutions.

Key features:

  • High-accuracy relative humidity & temperature sensor
  • Supports three-phase motor control
  • PWM output (MCU)
  • Up to 512KB program flash memory
  • Ultra-low power MCU
