Product Summary
HumiChip II is an improved version of HumiChip®, the most advanced and cost effective humidity and temperature sensing solution for virtually any type of applications.
Capacitive polymer sensor chip developed and fabricated in-house and CMOS integrated circuit with EEPROM are integrated into one embedded system in a reflow solder-able SMD package.
Individually calibrated and tested, HumiChip II performs ±2% from 20% to 80%RH (±4% over entire humidity range), and yet, is simple and ready to use without further calibration or temperature compensation.
Especially the sensor has an excellent temperature accuracy of ±0.2°C at the wide range(-20°C~60°C) which is beyond limit of previous humidity sensor technology.
HumiChip II matches pin-to-pin with HumiChip® so that HumiChip® users can replace easily and its extremely low current consumption makes it more suitable for battery-operating/portable devices.
HumiChip II applies newly developed polymer of SAMYOUNG S&C thus it has an outstanding performance in sub-zero temperature and hot environment.
