This document is a sales brochure for a product of a certain brand and model. It mainly introduces the function, features, usage and precautions of the product.
The HM1520 is a tubular humidity sensor designed for low‑humidity environments. It offers high stability, low temperature dependence, and a calibrated output that can be directly interfaced with a microcontroller.
The document lists electrical parameters, accuracy ranges, output signal characteristics, internal block diagram, and mechanical dimensions, helping designers integrate the sensor into their systems. This manual is written in Chinese.
| Humidity Range | 0‑100 %RH |
|---|---|
| Typical Accuracy (1‑20 %RH, 23 °C) | ±2 %RH / ±3 %RH |
| Temperature Range | -30 °C to 60 °C |
| Power Consumption | 0.4‑0.8 mA |
| Output Impedance | 70 Ω |
Typical accuracy is ±5 %RH at 55 %RH.
The sensor measures 9.70‑10.20 mm (A), 5.00‑5.50 mm (B), and 52‑54 mm (C).
