Mechanically robust and with a chemical and condensed waterproof sensing area, the digital IST AG HYT 271 humidity modules offer the widest application window and an optimal price-performance ratio. Precisely calibrated, the HYT 271 delivers an accuracy of ±1.8 % RH and ±0.2 °C and combines the advantages of a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The digital software integrated in the module processes the measured data and delivers the physical parameters of relative humidity and temperature over the I²C compatible interface as digital values. The HYT 271 humidity module is therefore fully interchangeable without adjustment and both the linearity error as well as temperature drift are corrected “on-chip” through computation resulting in an outstanding accuracy over a wide range of applications.
Further advantages of the HYT 271 digital humidity module include:
- Calibrated and temperature compensated
- Fast response time
- Excellent humidity/temperature accuracy and stability
- High chemical resistance
- Wide humidity and temperature range (0 % RH to 100 % RH and -40 °C to +125 °C)
- Very low drift
- I2C protocol (address 0x28 or alternative address)
- Very stable at high humidity
- Interchangeable without adjustment
The digital IST AG HYT 271 humidity module is suitable for various handheld measurement instruments, humidity transmitters, industrial applications, measuring technology and HVAC applications.
