When it comes to choosing the best Particulate Matter (PM) sensors to measure air quality, it can be difficult to know which one will best suit your needs. PMS7003 and SEN55 are two of the most popular sensors available, but how do they compare?
The PMS7003 is a digital universal particle concentration sensor that uses laser scattering to measure the particle concentration between 0.3 to 10 microns. The sensor is able to accurately measure concentrations of dust and aerosol particles in the atmosphere. It has a built-in temperature and humidity sensor and a fan for accurate measurement. It also has an LCD screen that displays sensor readings.
The SEN55 PM Sensor is a low-cost, easy-to-use particle matter detector, with a wide dynamic range and low operating costs. The device uses a laser scattering technique to measure the concentration of particles between 0.3 and 10 micrometers. The sensor features a dust benchmarking system, enabling accurate readings and a built-in fan for better air circulation. The design is slim and compact.
Both the PMS7003 and SEN55 can measure dust and aerosol particles in the atmosphere accurately and a built-in fan ensures better air circulation. The PMS7003 has a built-in temperature and humidity sensor and an LCD screen for data display. In comparison, the SEN55 is cheaper and easier to use, with a dust benchmarking system, a wide dynamic range, and a slim, compact design. In short, both the PMS7003 and the SEN55 are solid choices for measuring dust and aerosol particles, but the PMS7003 offers more features. It all depends on what's most important for your application.
