HTU20P(F) Humidity Sensor
Brand: American Sensor Technologies IncHTU20P(F) is a new humidity and temperature sensor by MEAS.
Setting new standards 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. 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.
Features- Full Interchangeability with no Calibration Required in Standard Conditions
- Instantaneous Desaturation After Long Periods in Saturation Phase
- Compatible with Automatized Assembly Processes, Including Pb Free and Reflow Processes
- Individual Marking for Compliance to Stringent Traceability Requirements
