Description

The GW8245/46/47/48 is a new generation of single-chip integrated temperature and relative humidity sensor, which integrates high-sensitivity MEMS humidity-sensitive components on silicon-based CMOS wafers, thereby reducing signal transmission interference, reducing device area and improving product reliability. The GW8245/46/47/48 uses I2C protocol to communicate with the host. Internal Cyclic Redundancy Check (CRC) generator calculates 8- bit checksum and sends to host after each of 16-bit data. Each GW824x series has a unique 32-bit serial number. It has a temperature measurement range of -40°C ~ +125°C. The test accuracy in the range of -40°C ~ +125°C is ±0.2 °C for GW8245/46/47, ±0.1 °C for GW8248. Relative humidity range is 0 ~ 100% with accuracy of ±1.8 %RH for GW8245/46/47, ±1.0 %RH for GW8248. The GW8245/46/47 has a heater inside of package, which can be used for anti-dew. The GW8245/46/47/48 can be used to process temperature and relative humidity monitoring and
control in various applications. The 4-pin dual-flat, no-leads package is suitable for surface mount technology (SMT).
