FAQ
The NextPM sensor offers several benefits that make it a leading solution for particulate matter (PM) monitoring across various applications.
- High Accuracy: The NextPM sensor ensures reliable PM measurements with high precision, detecting particles as small as 0.3 µm and providing readings for PM1, PM2.5, and PM10.
- Wide Detection Range: It covers a broad range of particle sizes, from 0.3 µm to 10 µm, allowing for comprehensive monitoring of different pollutants in the environment.
- Durability: With a lifespan exceeding 10,000 operational hours, the NextPM sensor is designed for long-term use in demanding environments.
- Low Power Consumption: The sensor consumes less than 70mA in active mode and even less in sleep mode, making it energy-efficient.
- Adaptability: It features an internal heater that automatically activates to maintain measurement accuracy under high humidity conditions.
The NextPM sensor is equipped with an automatic heater system that activates when the relative humidity exceeds 60%. This feature ensures measurement consistency by reducing the effect of humidity on particulate matter readings. Users can also manually control the heater through specific commands if needed. Additionally, the sensor’s sleep mode function helps conserve energy by stopping all non-essential operations when activated.
The NextPM sensor supports two main communication protocols:
- Proprietary UART Frames: The default communication method, providing simple commands for reading and writing data.
- Modbus Serial Protocol (TTL 3.3V): An industrial standard communication protocol that allows more flexibility and integration capabilities, especially in automated systems. This dual protocol capability enables the NextPM to be used in a variety of setups, from standalone operations to complex network integrations.
The NextPM sensor is robust and versatile, making it ideal for industrial applications where continuous monitoring and high reliability are required. Its features include:
- Resilience in Harsh Conditions: Capable of operating in temperatures ranging from -20°C to +70°C and in non-condensing environments of up to 95% humidity.
- Compliance: The sensor is CE, REACH, and RoHS compliant, ensuring that it meets international standards for safety and environmental impact.
- Ease of Integration: With options for open or sealed casings, it can be seamlessly integrated into HVAC systems or standalone air quality monitors.
