Overview

The CC2D23 is a fully calibrated and temperature-compensated humidity and temperature sensor from the Telaire ChipCap 2 series. It provides a 14-bit digital I2C output, offering a high precision +/-2% RH accuracy for demanding environmental monitoring applications. Designed for 3.3V operation, it features low power consumption and a compact 8-pin SMD footprint suitable for automated assembly.

Why Choose This Part

The sensor integrates a capacitive polymer humidity sensor and a silicon bandgap temperature sensor on a single chip, ensuring excellent long-term stability and a fast 7-second response time. It simplifies system design by being fully calibrated out of the box and featuring an alarm function for humidity threshold monitoring.

Applications

HVAC Control
Precise humidity and temperature monitoring for energy-efficient climate control systems in residential and commercial buildings.
Weather Stations
Reliable outdoor environmental sensing with a wide operating temperature range from -40C to 125C.
Medical Equipment
Monitoring moisture levels in respiratory therapy devices and neonatal incubators where accuracy is critical.
Industrial Automation
Process control in moisture-sensitive manufacturing environments such as semiconductor cleanrooms or food storage.

Getting Started

To interface with the CC2D23, connect the I2C SDA and SCL lines to your microcontroller with appropriate pull-up resistors to the 3.3V rail. Use the standard I2C protocol to read the 14-bit humidity and temperature registers; note that the sensor enters a low-power sleep mode automatically, drawing only 0.6uA when not active.
