The Telaire 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
