Description

The Winsen ZH03B Laser Dust Sensor employs a laser scattering principle to detect and quantify airborne particulate matter concentrations. It provides precise, real-time data for PM1.0, PM2.5, and PM10, making it a core component for environmental monitoring. The sensor’s internal signal conditioning ensures stable and reliable output.

Designed for continuous operation, the ZH03B features a low-power sleep mode and is built for long-term reliability in various environmental conditions. Its UART interface allows for direct digital communication with host controllers, while the PWM output provides a simple analog-like signal proportional to Particle concentration, facilitating integration into both DIY electronics and commercial air quality equipment.

Key Features

  • High-precision laser scattering detection for PM1.0, PM2.5, and PM10.
  • Factory calibrated for out-of-the-box accuracy and reduced setup time.
  • Dual-output flexibility with 3V TTL UART serial and PWM interfaces.
  • Low operating current (<120mA) and dormancy current (<10mA) for power-sensitive designs.
  • Robust construction for reliable operation in environments from -10°C to 50°C and 0-85% RH.
  • Compact and lightweight design for easy integration into space-constrained applications.
  • Long operational life cycle, rated for 3 years of continuous use in air.

Frequently Asked Questions

What is the output interface of the Winsen ZH03B sensor?

The ZH03B provides two primary output options: a 3V TTL UART serial interface for direct digital communication with microcontrollers and a PWM (Pulse Width Modulation) output. The PWM signal's duty cycle is proportional to the measured Particle concentration, offering a simple analog-like reading method.

What is the operating voltage and current requirement?

This sensor requires a stable 5V DC power supply (±0.1V tolerance). During active measurement, the operating current is less than 120mA. It also features a low-power dormancy mode where the current drops below 10mA, which is useful for battery-powered applications.

What Particle sizes does the ZH03B detect?

The sensor uses laser scattering to detect and provide separate concentration data for three Particle size ranges: PM1.0 (particles ≤1.0 micron), PM2.5 (≤2.5 microns), and PM10 (≤10 microns). This makes it suitable for detailed air quality analysis.

How do I communicate with the sensor via UART?

Connect the sensor's TX/RX pins to your microcontroller's UART pins, ensuring logic level compatibility (the sensor uses 3V TTL). The sensor uses a standard serial protocol; you must send specific command frames to request data and then parse the returned data packet containing the PM concentration values.

What is the sensor's response time and operating environment?

The T90 response time (time to reach 90% of final reading) is 45 seconds or less. It is designed to operate reliably within an ambient temperature range of -10°C to 50°C and a humidity range of 0% to 85% RH (non-condensing).
