NoiseMeter first prototype

First Prototype

NoiseMeter is to our knowledge the first SigFox connected class2 Sound Level Meter. Targeting professional Acoustics Engineering in environmental (traffic, engines), construction and noise at work assessments, NoiseMeter enables you to long-term and swarm measurement. Hardware verification was achieved last week as we connected our sensor board (analog true rms to dB) to the MCU and SigFox board we set up connection with (prototype 0). Already next week, we will deliver BOM to the assembly house, beginning of January we will deliver layout to the PCB manufacturer. In the meanwhile, testing of prototype 0 including set up server integration (QTTP) and App (IOS first, Android 2nd) programming will go on.
