Honeywell HIH-4000 series humidity sensors are high-precision, low-power, instrument-grade RH (relative humidity) sensors with a solderable single-in-line pin (SIP).
The HIH-4000 series humidity sensors are designed for OEM use with a near‑linear voltage output, low power consumption (typical 200 µA), and high accuracy. They feature a laser‑corrected polymer capacitive element that offers good chemical resistance and stability across a wide range of environments, making them suitable for HVAC, medical, and other applications.
The datasheet lists key electrical and environmental specifications, including supply voltage, current, accuracy, response time, and operating temperature ranges. It also provides mechanical dimensions, typical application circuits, and ordering information for the different package options. This manual is written in Chinese.
| Supply voltage | 4 – 5.8 Vdc |
|---|---|
| Supply current | 200 – 500 µA |
| Accuracy (best‑fit line) | ±3.5 %RH |
| Repeatability | ±0.5 %RH |
| Response time (1/e) | 15 s |
| Stability at 50% RH | 1.2 %RH |
| Operating temperature | -40 °C to 85 °C |
| Operating humidity | 0 %RH to 100 %RH |
| Storage temperature | -50 °C to 125 °C |
The sensor typically draws 200 µA and can draw up to 500 µA.
It offers a best‑fit line accuracy of ±3.5 %RH.
The 1/e response time is about 15 seconds in slowly moving air.
The sensor operates from –40 °C up to 85 °C.
