Datasheet HS1101LF (TE Connectivity) - 3

HS1101LF Relative Humidity Sensor MEASUREMENT FREQUENCY INFLUENCE In this data sheet, all capacitance measurements are done @ 10 kHz / 1Volt. However, the sensor can operate without restriction from 5 kHz to 300 kHz POLARISATION In order to get a better reproducibility during measurements, always connect the case of the header (pin 2) to the ground of the circuit. The case of the header is located on the opposite side of the tab. SOLDERING INSTRUCTIONS We recommend taking specific attention to soldering conditions to get the best performance of MEAS-France sensors. See Application Note.
