Honeywell HPM Series PM2.5 Sensor
Overview
The HPMA115S0-XXX is a laser-based particulate matter sensor designed to detect and measure PM2.5 and PM10 concentrations in the air. It utilizes light scattering technology to provide accurate, fully calibrated particle readings over a range of 0 ug/m3 to 1,000 ug/m3.
Why Choose This Part
The sensor is fully calibrated at the factory and features heavy industrial level IEC61000 EMC protection for high reliability in noisy environments. It offers a long service life of 20,000 hours of continuous use and provides fast response times of less than 6 seconds.
Applications
Key Specifications
Getting Started
Connect the sensor to a microcontroller via the UART interface using 3.3V or 5V logic levels, though the sensor requires a stable 5V supply (4.8V to 5.2V). Use the standard Honeywell serial protocol to poll for measurements or set the device to auto-send mode for continuous data streaming.
