Relative Humidity and Temperature Sensor with I²C Interface

TH09C-.png

General Description:


The TH09C integrates one relative humidity sensor and one high-accuracy temperature sensor. The device is encapsulated in a QFN4 package and includes an I²C slave interface for communication with a master processor. 


Key Benefits and Features:


  • Ultra-accurate: Temperature sensor (±0.15°C) 

                            Relative humidity sensor (Typ:±2.0%RH)

  • Wide sensing range: Temperature operating range (–40°C to 100°C) 

                                     Relative humidity operating range (0% to 100%)

  • Wide operating voltage: 1.71V to 3.60V

  • Small foot-print: 2.0mm x 2.0mm x 0.75mm

  • Industry standard two-wire interface: Standard (100kbit/s) and fast (400kbit/s) I²C

  • Low power: Automatic low-power standby when not measuring 

                        Active current: 6.6μA @ 1Hz (1.8V)

                        Standby current: 40nA

  • Cost effective: Digital pre-calibrated relative humidityand temperature sensor 

                            *  Output directly in %RH and Kelvin 

                            *   Wide supply voltage range

  • High reliability: Long-term stability


Applications:  


  • Building Automation / Smart home / HVAC1

       * Indoor air quality detection

       Demand-controlled ventilation

       Smart thermostats

  • Home appliances

       * Air cleaners / purifiers

       * Refrigerators, washing machines, dishwashers, dryers

  • Mobiles / Wearables

  • IoT devices

  • Portable devices for personal health and wellness

  • Weather stations
