Relative humidity and temperature sensor DHT9X

digitalfor HVACdust

Digital temperature and humidity sensor module DHT9x integrates sensing elements and signal processing to deliver fully calibrated digital outputs. It incorporates proprietary CMOSens® technology, ensuring high reliability and excellent long-term stability. The sensor combines a capacitive polymer humidity-sensing element and a band-gap temperature-sensing element on a single chip, which interfaces seamlessly with a 14-bit A/D converter and serial interface circuitry. This integration results in superior quality, ultra-fast response (typically less than 4 seconds), strong anti-interference capabilities, and high cost-effectiveness. - The simple two-wire serial interface and internal voltage regulation facilitate quick and easy integration into peripheral systems. It is an ideal choice for a wide range of applications, including data loggers, transmitters, automated process control, automotive industry, building automation/HVAC, and medical equipment. The sensor is offered in a 4-pin package. Relative Humidity Measurement Performance - Parameter: Typ.
