SENSIRION SHT21P Humidity and Temperature Sensor
The SHT21P is a humidity and temperature sensor that integrates a capacitive humidity sensor, a bandgap temperature sensor, and specialized analog and digital circuitry on a single CMOSens® chip. This design offers high accuracy and stability with low power consumption. The sensor features a protective over-molding (excluding the humidity sensing area) for durability and long-term stability. It provides fully calibrated measurements, an analog output with PWM interface, and operates within a temperature range of -40°C to 125°C. The standard version has an accuracy of ±2% relative humidity and is suitable for both high-volume production and low-volume applications, including sensing and instrumentation, as well as signal processing.
