It is a standard LoRa communication smart sensor that can acquire and detect indoor PM2.5, temperature and humidity. Its measurement and transmission are highly reliable and stable.
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.
