Our unique light sensor measures the intensity of the room's light and automatically calibrates the brightness of the image on the screen. In a sun-filled environment, the picture grows even brighter, and in dim surroundings, intensity is reduced. So now you're saving energy on a bright screen when it isn't needed. You're enjoying the best picture possible with a TV that's aware of its surroundings.
The resistivity of the water after filtration can be measured in the hundreds of MΩ—very close to theoretically perfect resistance for water. This machine records with two probes, just like a normal DMM.

El lago Chad (del francés: Lac Tchad) es un lago endorreico poco profundo que se encuentra situado en la frontera entre Chad, Níger, Nigeria y Camerún, en África. Su capacidad ha ido menguando con el paso del tiempo y debido, sin duda, a la desertización provocada por la cercanía del desierto del Sahara y por la captación de aguas para irrigación de cultivos. Se ha calificado como uno de los mayores desastres medioambientales ocurridos en la historia reciente, semejante al del Mar de Aral en Asia. (es.wikipedia.org/wiki/Lago_Chad)
El índice diferencial de humedad normalizado o NDMI detecta los niveles de humedad en la vegetación utilizando una combinación de bandas espectrales del infrarrojo cercano (NIR) y del infrarrojo de onda corta (SWIR). Es un gran indicador del estrés hídrico en los cultivos.
En color azul oscuro se muestran los mayores niveles de humedad. El color rojo corresponde a suelos estériles, secos.
The normalized difference moisture Index (NDMI) is used to determine vegetation water content and monitor droughts. The value range of the NDMI is -1 (red) to 1 (dark blue). Negative values of NDMI (values approaching -1) correspond to barren soil. Values around zero (-0.2 to 0.4) generally correspond to water stress. High, positive values represent high canopy without water stress (approximately 0.4 to 1).

I see sensor dust - lots of it - balls. That means I need to get in there and clean it off. New territory for me. Any tips would be welcome.
I've added the white box to hide the private parts, as I couldn't set the photo to restricted since I'm not a premium member.
If you've got an expensive camera with a sensitive sensor, you've got to give it something to think about sometimes, right?
When you have the right approach to consider the best sensor in the industrial sector, it is possible to come with best automotive sensor that are certainly the most used smart devices to meet all the automotive needs.

Always a good thing to clean the sensor from time to time. Especially when you have specks on the photos. I use the wet method. Not too hard to do, but needs to be done correctly.
