® ChipCap® 2 Fully-Calibrated Humidity and Temperature Sensor Features • Fully-calibrated and temperaturecompensated • Digital or analog output with alarm function • Precision and 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 • Automobile and transportation—cabin climate control, defogging control condensing preventive device • Medical—nebulizers, Oxygen Air, CPAP/ Sleep Apnea Devices • OEM Assemblies Available Amphenol Advanced Sensors 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 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 Sensor Performance Relative Humidity (RH%) Resolution 14 bit (0.01%RH) Resolution Temperature (°C) 1 14 bit (0.01°C) Accuracy ±2.0 %RH (20~80%RH) Accuracy ±0.3°C Repeatability ±0.2 %RH Repeatability ±0.1°C ±1.0 %RH Response time2 5.0 sec (τ 63%)
