Sensitivity and Noise Evaluation of an Optoelectronic Sensor for Mosquitoes Monitoring

Mosquitoes play a biological role of significant impact on public health, being vectors of several diseases transmission. In particular, the Aedes aegypti mosquito is a vector of potentially fatal diseases such as Dengue, Zika, Chikungunya, and Yellow Fever. The studies progress on these insects biological properties is fundamental for the improvement of more accurate mosquitoes detection sensors. Therefore, the optoelectronic sensors for flying insects detection and classification taking into account the fundamental wingbeat frequency of several insects species database available in the literature. Also, the optoelectronic approach is capable to perform insect sensing without needing uninterrupted data recording. This functionality is essential to reduce the sensor's power consumption and enable the construction of a low-power device ready for an Internet of Things (IoT) scenario. In this regard, this paper aims to design and deploy an optoelectronic sensor module to validate the optoelectronic sensor operating principle and evaluate the main optical interference sources. Thus, it is possible to determine the best sensor's operating bandwidths for an optimal signal-to-noise ratio and efficiency.
