Monitor Workplace Noise Levels with the Browan LoRaWAN® Sound Level Sensor
Ensure occupational health and safety compliance and maintain optimal working conditions by accurately monitoring noise levels with the Browan Sound Level Sensor (TBSL100). This compact LoRaWAN® device utilizes a sensitive MEMS microphone to measure A-weighted sound levels (dBA) within a range relevant to most industrial and commercial environments (40-100 dBA). Easily deployable and battery-powered, it provides valuable data for noise mapping, identifying loud machinery, and ensuring adherence to workplace regulations. Manusphere can help integrate this sensor data into your EHS (Environmental Health and Safety) or facility management systems.
Addressing Noise Challenges in Industrial Environments
Excessive noise can impact productivity, safety, and regulatory compliance. The TBSL100 sensor helps manage workplace acoustics:
- Challenge: Monitoring noise exposure levels in work areas to comply with Occupational Health and Safety (OHS) regulations and protect employee hearing.
- Solution: Accurately measures sound levels within the 40-100 dBA range with 1 dB resolution, providing the necessary data to assess noise exposure and implement corrective actions if needed.
- Challenge: Identifying specific machinery or processes that are sources of excessive noise pollution within a facility.
- Solution: Compact, battery-powered design allows for easy placement near potential noise sources to pinpoint issues and track levels over time, aiding maintenance and noise mitigation efforts.
- Challenge: Ensuring designated quiet zones (e.g., offices, labs adjacent to production areas) remain within acceptable noise limits.
- Solution: Provides continuous or periodic monitoring data transmitted wirelessly via LoRaWAN®, allowing facility managers to verify noise levels in sensitive areas.
- Challenge: Deploying noise monitoring easily without requiring complex wiring or frequent battery replacements.
- Solution: Features a small footprint, is powered by a single ½ AA Li-SOCl2 battery offering up to 16 months of estimated lifetime (*dependent on reporting frequency and environment), and uses LoRaWAN® for long-range wireless communication.
