Description

  • High-precision measurement with reliable data: The temperature measurement range typically spans -40 degrees Celsius to 80 degrees Celsius with an accuracy of +/- 0.5 degrees Celsius, while the humidity measurement range covers 0 per cent to 100 per cent RH with an accuracy of +/- 2 per cent RH. This enables precise capture of subtle environmental temperature and humidity fluctuations, meeting the data accuracy requirements for industrial monitoring, home sensing, and similar applications.
  • Digital signal output with simplified wiring: Employing single-bus digital signal transmission, connection to devices such as microcontrollers requires only three wires (VCC, GND, DATA). This eliminates the need for complex analogue-to-digital conversion circuits, thereby reducing wiring complexity and lowering the barrier to entry.
  • Low-power design, extended battery life: With low static power consumption and even lower energy usage in sleep mode, it is ideal for battery-powered portable devices or long-term uninterrupted monitoring scenarios. This effectively extends device runtime while reducing power supply maintenance costs.
  • Highly stable and adaptable to diverse environments: Possesses excellent interference resistance, enabling stable operation in harsh conditions such as dampness and low-dust scenarios. The sensor probe features a waterproof encapsulation design (in certain versions), allowing direct use for outdoor monitoring or in environments with elevated humidity levels.
  • Widely compatible with diverse applications: Compatible with mainstream 51 microcontroller development boards, suitable for smart home control, greenhouse monitoring, industrial environment regulation, electronic DIY projects and other scenarios, offering strong practicality.
