Description
PM2.5 sensor is designed to measure Particle, Temperature and Humidity by LoRa long-range and low-power wireless connectivity. It is integrated LoRa wireless technology, Laser dust (PM2.5) Sensor knowhow and high-performance MCU solution for various IoT markets usage. With calibrated dust (PM2.5) sensor module and compensated Temperature/Humidity sensor integration, the data is ready for use. It is perfect to detect the dust in the air, like air purifier, air conditioner and air monitor.
