Features - Accuracies ΔRH = ±1.0 %RH, ΔT = ±0.1 °C - VDD = 1.08 V … 3.6 V - Avg. current: 0.4 µA, Idle current: 80 n A - I2C FM+, CRC checksum, multip. I2C addr. - Patented protection options [1], PTFE membrane and removable protective cover General Description - Operating range: 0 … 100 %RH, - 40…125 °C - Fully functional in condensing environment - Power heater, true NIST-traceability - JEDEC JESD47 qualification - Sensor-specific calibration certificate acc. to ISO 17025 : 2017, 3-point temp. calibration SHT4x is a digital sensor platform for measuring relative humidity and temperature at different accuracy classes. Its I2C interface provides several preconfigured I2C addresses while maintaining an ultra-low power budget (0.4 μW). The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments. The four-pin dual-flatno-leads package is suitable for surface mount technology (SMT) processing and prises an optional on-package patented PTFE [1] membrane or a removable protective cover. Sensor specific calibration certificates according to ISO17025, identifiable through unique serial number, are available.
