HTU21P Analog High Accuracy RH/T Sensor

HTU21P(F) is a digital humidity and temperature sensor for OEM applications. Setting the standard in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3 x 0.9 mm foot print.  This sensor provides calibrated, linearized signals in analog pulse width modulated (PWM) format. HTU21P(F) humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. These low power sensors are designed for high volume and cost sensitive applications with tight space constraints. PWM signal runs on a base frequency of 120Hz, the data signal is provided on SDA line. Pulling SCL high or low allows for switching between humidity and temperature, respectively. The sensor measures twice per second. The PWM signal may be converted to an analog ratiometric interface by adding a low pass filter.
