ChipCap 2
Features
™
A Fully Calibrated Humidity
and Temperature Sensor
• Fully Calibrated & Temperature Compensated
• Digital or Analog Output with Alarm Function
• Precision & Accuracy (±2%RH, ±0.3°C, 14 bit )
• Free Operating Voltage (min 2.7V to max 5.5V)
• Low Current Consumption
• SMD Package for Automated Assembly
• Reliable in Harsh Environments
ChipCap 2 offers the most advanced and cost
effective humidity and temperature sensing
solution for virtually any type of application.
A capacitive polymer sensor chip and a CMOS
integrated circuit with EEPROM are integrated into
one embedded system in a reflow solderable SMD
package.
Individually calibrated and tested, ChipCap 2
performs at ±2% from 20% to 80% RH (±3% over
entire humidity range), and is simple and ready
to use without further calibration or temperature
compensation.
ChipCap 2 provides linear output signals in various
interfaces to customer requirements:
• I²C interface
• PDM convertible to analog signal
• Alarm function for preset control at min/max
humidity
Applications
• Energy Saving HVAC Control —Air Conditioning,
Refrigeration, Indoor Air Quality, Vent Fans,
Home Appliances, Humi/Dehumidifiers
• Process Control & Instrumentation—Medical
Instruments, Handheld Devices, Weather
Stations, Food Processing, Printers, RFIDs
• Automobile & Transportation—Cabin Climate
Control, Defogging Control Condensing
Preventive Device
• Medical — Nebulizers, Oxygen air, CPAP/Sleep
Apnea devices
• OEM assemblies available
