The Honeywell HIH-4000-004 is a high-reliability analog humidity sensor providing a linear voltage output (0.8V–3.9V) proportional to relative humidity (0–100% RH). With ±3.5% RH accuracy and low power consumption (200μA), it is ideal for HVAC systems, environmental monitoring, and industrial controls. The sensor operates over a wide temperature range (-25°C to 85°C) and features excellent long-term stability (±1% RH/yr). Its 3-pin SIP package allows for easy integration into PCB designs.
