Wireless Particulate Matter Transmitters

Ambient Weather PM25 Outdoor Particulate Monitor

Find it on Amazon

Why choose it

Choose the PM25 for outdoor fine-particle readings with a listed compatible Ambient Weather receiver, including the WS-2000, WS-2902C and WS-5000.1 Reporting takes one minute with the optional AC adapter or ten minutes on battery power, so choose the power setup around how often you want new readings.2

Before you buy

Mount it under a patio or carport with clear airflow. Rain and fog can inflate the readings, so avoid an exposed, damp location.1 Plan for monthly USB charging even with the solar panel.1
