WSLRW-SL is a LoRaWAN noise sensor with a measuring range of 30-120 dB(A) for residential, office, factory, construction sites, and public areas... Capacitive technology has high sensitivity, accuracy, and stability. LoRaWAN connectivity enables kilometer-long data transmission to LoRaWAN Gateways. With an ultra-low power design and intelligent firmware, the sensor can operate for up to 10 years with only 2 AA batteries (depending on configuration), or use solar panels for applications of continuous monitoring. The device supports all LoRaWAN bands worldwide.
For Applications
Ambient Air Quality Monitor, Facility Monitoring, Machine Health Monitoring, Safety Monitoring
Wide frequency range
Allows measurement from 20-12,500 Hz
10-Year battery
Use batteries for up to 10 years, or use solar panels for continuous monitoring applications.
