@thehighestbit/node-red-contrib-decibel-meter 1.0.1
A node red node for communicating with the PCB Artists Decibel Meter sensor.
node-red-contrib-decibel-meter
A Node-RED node for using the I2C Decibel Sound Level Meter Module from PCB Artists.
Installation
npm install @thehighestbit/node-red-contrib-decibel-meter
Configuration
- I2C Bus - Which i2c bus the sensor is connected to
- Address - i2c address of the sensor, almost certainly 0x48
- Type - If the sensor is Regular or Spectrum Analyzer
- Filter - The type of weighting to use
- Avg time - The averaging time the sensor will use to calculate the dB value
- Interval (ms) - The interval between outputs from this node (if 0, then output can only be triggered by sending this node a message with any payload). It will output both the current values and additionally also the min, max and avg of the entire interval. Make sure that interval <= 100 * avg time, since the device can only store 100 dB readings at a time.
