HVAC Humidity Sensors Renesas Electronics HVAC Humidity Sensors include the RL78/G14 microcontroller and HS300x sensor to provide a motor control system with relative humidity/temperature measurement for predictive failure diagnostics. This Renesas solution supports the appliance safety standard IEC/UL 60730 and closed-loop feedback with relative/humidity temperature to recirculate outdoor to indoor air. Power and timing solutions are also available to complete these solutions.
