Integrated humidity sensor: HIH4000-003 HIH4010-003 Honeywell's HIH4000 humidity chip, tried and tested. Honeywell's relative humidity sensor is a thermosetting polyester capacitive sensor with signal processing function, linearly amplified output, factory calibration, and a unique multi-layer structure can resist environmental erosion, such as moisture, dust, dirt, oil , And some chemicals. The HIH-4000 humidity sensor is designed for high-volume OEMs, with instrument-level measurement performance, low cost, and SIP packaging. The linearly amplified voltage output can make the device directly consistent with the controller or other devices, reduce and eliminate the calibration cost during OEM production, and the manufacturer can provide single sensor calibration data.

1. Brief introduction of humidity sensor HIH4000 series:
The HIH-4000 product series is a relative humidity sensor with instrument-level quality. The corrosion resistance of the product makes them the best choice for harsh environments. The HIH-4000-003 series humidity sensor is designed for large OEMs. The linear output voltage of the sensor can be directly input to the controller or other equipment. Typical operating current is only 200μA, suitable for low power consumption, battery-powered systems. The close consistency construction even eliminates the calibration cost of OEM production.
