-02 sensitive adopts SHT3X, a newly designed CMOSens chip, an improved capacitive humidity sensor and a standard bandgap temperature sensor , whose performance has been greatly improved and even exceeds the reliability level of the previous generation of sensors (SHT1x and SHT7x). It makes its performance more stable in high humidity environment. -02 temperature and humidity transmitter is designed based on -485 communication interface, compatible with standard Modbus-RTU protocol, and can be connected to Modbus network to measure and monitor temperature and humidity. -02 adopts the address setting method of dip switch, avoiding the need to set the address in advance with the host computer, which is simple, convenient and easy to maintain and replace. -02 has excellent long-term stability, low hysteresis, low power consumption, strong resistance to chemical pollution and excellent repeatability. It is an ideal solution for accurately measuring temperature and relative humidity in HVAC, communication room, warehouse building and automatic control applications.
