it's important to note that the sensor measures illuminance in lux units, which are specific to light intensity as perceived by the human eye. It does not measure irradiance in watts per square meter (W/m²), which refers to the power per unit area received from the sun or other sources. If you need to convert lux to watts per square meter, it's a bit complex because it depends on the wavelengths of the light and the efficiency of the light source in converting electrical power to light. However, for sunlight, a rough conversion factor is about 0.0079 watts per square meter per lux. This factor can vary depending on the type of light source and the specifics of the situation. If you need precise measurements in W/m² for specific applications, you might consider using a pyranometer or a similar device designed for measuring solar irradiance.
in a project of painel solar, what's the difference between ldr sensor and this sensor ? the utilities of both are monitoring light, so what's the difference and which one is better?
Both the LDR and BH1750 sensors serve to monitor light, but they differ in accuracy and sensitivity. LDRs are cost-effective but less precise, affected by environmental factors. BH1750 offers superior accuracy and stability, making it ideal for precise applications like solar panel control, despite being pricier. The choice depends on your project's requirements for accuracy, reliability, and cost-effectiveness.
Very good work, sir !
Is it possible to change the lux value of BH1750 sensor in W/m2 ? Thank you
