Measure Temperature with a Sensor Made for Embedded Builds

The Air Quality Monitor PM 2.5, Formaldehyde, Temperature & Humidity Sensor is a dust sensor designed for climate logging, weather nodes, and room monitoring. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.

Key details include Particle Range of measurement: 0.3 ~ 1.0μm; 1.0 ~ 2.5μm; 2.5 ~ 10μm; Particle Resolution: 1ug / m³.

Important: Most gas and chemical sensors work best after warm-up and calibration. Readings can drift with temperature, humidity, and sensor age.
