ANALOG HUMIDITY TEMPERATURE SENSOR

The HTU20P(F) miniature RH/Temperature sensor provides calibrated, linearized signals in analog pulse width modulated (PWM) format. HTU20P(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. With TE's improvements and miniaturization of the sensor, the performance-to-price ratio has been improved – and eventually, any device should benefit from the cutting edge energy saving operation mode. HTU20 is also available with digital I²C (HTU20D(F). Optional PTFE filter/membrane (F) protects HTU20P analog humidity sensors against dust and water immersion, as well as against contamination by particles.
