HS1101 Capacitive Humidity Sensor

Relative Humidity Capacitance Standard: Based on a relative polymer capacitive cell that varies its capacitance linearly in response to ambient relative humidity changes.

Fast Response Time & Interchangeability: Delivers fast response times with complete interchangeability under standard calibration conditions without requiring individual calibration.

Wide Humidity Measurement Spectrum: Measures relative humidity accurately across a broad range of 1% RH to 99% RH with excellent long-term stability and reliability.

Direct Frequency Circuit Integration: Designed to work seamlessly in frequency-output circuits (e.g., NE555 timer oscillator circuits) where capacitance changes directly translate to measurable frequency shifts.

Robust Lead Component Package: Housed in a durable, compact plastic package with through-hole lead pins for easy PCB mounting or integration into custom environmental sensing probes.

Housing Material: High-durability polymer cell housing with gold-plated/solderable through-hole leads.

Technical Specifications:

Sensor Type: Capacitive Relative Humidity Sensor.

Nominal Capacitance: 180 pF at 55% RH (10 kHz).

Operating Humidity Range: 1% – 99% RH.

Operating Temperature Range: -40°C – +100°C.

Color: Black Package with Metallic Wire Legs.

Usage Advice: Pair with an RC oscillator circuit (such as a 555 timer) to convert variable capacitance into a digital frequency signal easily read by microcontrollers.

Maintenance: Protect the central sensing membrane from direct condensation, oils, and particulate accumulation to maintain high measurement accuracy and prevent capacitance drift.

Essential Analog Humidity Component: Position as an ideal discrete humidity-sensing component for HVAC equipment, weather station design, dehumidifiers, and custom embedded systems.

Highlight Linear Capacitive Output: Emphasize how its predictable capacitance-to-humidity curve enables clean signal generation in frequency modulation circuits without needing complex lookup tables.

Recommended Cross-Sell Add-ons: Pair with DHT11 Temperature & Humidity Sensor Module, AM2302 (DHT22) Temp & Humidity Sensor, HTU21D Temperature & Humidity Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
