New iot lux-meter with high-precision light sensor for long-term data recording
Creators
Description
In this present work, we have developed a new IoT lux-meter prototype to measure illuminance with high precision, based on the NOA1305 type light sensor using a smart memory management strategy. The NOA1305 sensor device has a linear response over the range of near 0 lux to over 100k lux with programmable count times to optimize noise performance. The proposed illumination measurement prototype, based on ESP8266 Node MCU board, is associated to more compounds including SD card, LCD screen and the RTC, which allows an automatic and a real time record, display, and Wireless data communication. Furthermore, we have developed and implemented a web interface using HTML and java script language into the ESP8266 module, which is configured as a server for tele-management and supervision, via internet, of recorded In this present work, we have developed a new IoT lux-meter prototype to measure illuminance with high precision, based on the NOA1305 type light sensor using a smart memory management strategy.

Finally, this new intelligent prototype was tested and validated, inside a photographic darkroom, by comparing its measurement results with those acquired by the "Spectroline NDT XR-1000 AccuMAX" digital radiometer, under the same experimental and environmental conditions
