HS1101 Humidity Sensor Module MD1101 Capacitive Hygrometer for DIY Projects Fast Humidity Response

1PCS HS1101 MD1101 Humidity Sensor White Black A compact, capacitive humidity sensor for electronic projects and environmental monitoring. The HS1101 MD1101 is a sensitive capacitor hygrometer that detects relative humidity changes and delivers a stable, fast response for integration into measurement and control systems. Key benefits Sensitive capacitive measurement that responds quickly to humidity changes Single piece supply for prototyping or replacement needs Compact footprint and lightweight design for easy mounting in enclosures or samples Available in white or black finish to match your device aesthetics Simple integration into circuits that measure capacitance or use a capacitance to voltage conversion stage What it does and how it helps Measures relative humidity using a capacitive sensing element. Changes in humidity alter the sensor capacitance, allowing connected electronics to translate those changes into readable values. Provides a reliable sensing element for systems that need humidity feedback without bulky sensors or complex optics. Ideal when you need a direct sensor element for custom circuits, data loggers, or embedded controls. Compatibility and installation Intended for use with capacitance measurement circuits, capacitance to voltage converters, or microcontroller front ends that support capacitive sensors. Works well as a drop in sensing element for DIY boards, experimental setups, and projects. Requires basic signal conditioning and calibration in your circuit for accurate relative humidity readings. Typical applications Environmental monitoring modules and DIY weather stations Humidity control for greenhouses, storage cabinets, and instrument enclosures Electronics moisture detection and process control in HVAC or industrial systems What to expect in the package One piece HS1101 MD1101 capacitive humidity sensor in white or black finish, ready for integration into your measurement circuit. Notes This product supplies the sensing element only. A suitable interface circuit is required to convert capacitance variation into usable humidity data.
