The document provides information about the features and characteristics of a specific product, including its design, functions, and performance.
The HM1500 is a linear‑voltage output humidity sensor designed for OEM applications that require precise and reliable humidity detection. It features a small, easy‑to‑install connector, low drift, high reliability, and resistance to chemicals and harsh environments.
The manual lists the sensor's electrical parameters, measurement range, typical output curves, error budget, temperature compensation, and environmental qualifications. It also includes wiring diagrams, dimensions, and special handling precautions. This manual is written in Chinese.
| Supply voltage (peak) | 7 Vdc |
|---|---|
| Humidity range | 0~100 %RH |
| Temperature range | -30~60 °C |
| Supply voltage (operating) | 4.75~5.25 V |
| Typical output at 55 %RH | 2.42~2.54 V |
| Current consumption | 0.4~0.8 mA |
| Sensitivity | +25 mV/%RH |
| Drift | 0.5 %RH/yr |
| Response time (5~10 %RH, static, 63 %) | 10 s |
It can measure relative humidity from 0 %RH up to 100 %RH.
The output voltage is linear with humidity, expressed by the equation yout = 25.68 × RH + 1079 (mV).
