Environmental Sensor

Temperature & Humidity Sensor

The temperature & humidity sensor integrating polymer dielectric film and CMOS mixed signal integrated circuits in single package. Its performance was fully proven at various applications and harsh test environment. Every sensor is individually calibrated and tested, so it outputs fully calibrated performance by digital (I2C, PWM, PDM) or analog (voltage) interfaces. Its analog output allows for cost effective system eliminating additional analog conversion components.
