HS1101LF Relative Humidity Sensor  
Frequency Output Circuits  
This circuit is the typical astable design for 555. The HS1101LF, used as variable capacitor, is  
connected to the TRIG and THRES pin. Pin 7 is used as a short circuit pin for resistor R4.  
Note: R22=499kS /  
R4=49.9S? / R1=1 kS /  
RV1=50 kS potentiometer /  
C1=10nF / C2=2.2nF / C3=100nF  
The HS1101LF equivalent capacitor is charged through R22 and R4 to the threshold voltage  
(approximately 0.67Vcc) and discharged through R22 only to the trigger level (approximately  
0.33Vcc) since R4 is shorten to ground by pin 7.  
Since the charge and discharge of the sensor run through different resistors, R22 and R4, the duty  
cycle is determined by:  
- thigh = C@%RH*(R22+R4)*ln2  
- tlow= C@%RH*R22*ln2  
- F = 1/(thigh+tlow) = 1/(C@%RH*(R4+2*R22)*ln2)  
- Output duty cycle = thigh*F = R22/(R4+2*R22)  
To provide an output duty cycle close to 50%, R4 should be very low compared to R22 but never  
under a minimum value. Resistor R3 is a short circuit protection. 555 must be a CMOS version.

HS1101LF Relative Humidity Sensor  
Measurement Error vs Stray Capacitance  
-Special attention is required in order to  
minimize stray capacitance in the layout. The  
added capacitance will act as a parallel  
capacitance with the sensor and create a  
measurement error.  
-A careful coating of PCB and components  
must be implemented to prevent unexpected  
deviations of Fout in high humidity conditions.  
Qualification Process  
HS1101LF sensors have been qualified through a complete qualification process taking in account many of the requirements of the JEDEC standard including:  
• Temperature Cycling - 40°C / +125°C  
• Solder heat and solderability including lead free process.  
• Pb free wave soldering and reflow soldering process(260°C) + DI water clean at 45°C  
• Mechanical shock JESD-22-B104-A  
• Vibration - Variable frequency(20 to 2000Hz) JESD-22-B103-A  
• Marking permanency  
• High Temperature / Humidity Operating Life - 93%RH / 60°C for 1000 hours  
• Low Humidity storage life - RH < 10%/23°C - 1000 hours  
• Resistance to immersion in water at ambient temperature and 80°C  
High temperature storage 140°C for 168 hours.  
• Resistance to many chemicals linked to home appliances/automotive  
or consumer applications.  
• ESD - Electrostatic Discharge –Air Gun +-15kV(IEC 1000)  
• Salt Atmosphere JESD22-A107-A  
ENVIRONMENTAL AND RECYCLING  
HS1101LF sensors are lead free components and are compatible with Pb Free soldering processes. HS1101LF sensors are  
free from Cr (6+), Cd and Hg.
