WS302 is an advanced LoRaWAN® Sensor for monitoring noise/sound level in decibels (dB).

Model/Product no.: V0226

Offers the choice of A-weighting or C-weighting based on scenarios. Usually, A-weighting is appropriate for quiet environments while C-weighting is for noisy environments. Fast-time weighting uses a time constant of 125 milliseconds for measuring fast-changing noise with large fluctuations. Supports the reporting of three sound level values (maximum sound level, sound pressure level, and equivalent continuous sound level) based on different weighting methods. Minimalistic and modern design makes it ideal for classrooms, workplaces, hotels, hospitals, etc. Milesight Sound Level Sensor is compatible with industry-standard LoRaWAN® gateways with a range of up to 15 km in rural areas and 2 km in urban areas.
