    FAQ

    It processes the raw signals from the sensing elements, compensates for errors such as temperature drift, and converts them into stable output signals (e.g., 0–3V analog voltage). This ensures high accuracy, long-term stability, and easy system integration.

    An analog humidity and temperature sensor is a device that measures relative humidity and temperature in the environment and provides an analog voltage output (e.g., 0–3V). These sensors are widely used in home appliances, HVAC systems, and smart devices for accurate environmental monitoring.

    The sensor typically integrates a capacitive humidity sensing element and a temperature sensing element (such as an NTC thermistor). Changes in humidity or temperature cause variations in capacitance or resistance, which are processed by an ASIC chip to generate a stable analog voltage signal proportional to the measured values.
