    Abstract:

    Based on a 512 × 2-element InGaAs spectrum module, a new spectral-sensing IoT node is developed. The detector uses two parallel column structure with 25 μm pixel pitch. In order to reduce the impact on an abnormal response to a single pixel, the data onto two channels is averaged in the circuit. The experimental results show that the test wavelength range of this node is 976~1700 nm, and the spectral resolution is 13.5 nm. The wavelength accuracy is better than 3.2 nm, and the wavelength repeatability is better than 0.3 nm. The dynamic range is 2300:1, and the absorbance repeatability is 0.0011 AU. The baseline stability of light source is better than 0.0001 A/h. The function of the sensor node was verified by using alcoholic beverages samples of different nominal concentrations.
