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
• 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
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
