Hi there. new and curious.

Hello, i've been looking for some Droid foarms and this seems like the best one so i joined

so far i love android . sooooo much beter than the iphone!

anyway i knoticed somting while using my new droid 2 in the sunlight. it was hard to take a picture but this is the best one out of some 50 shots. digital cameras FTW!

u see the notice light, well whats the other 3 things?

from left to right: 1 and 2 look like a "beam" option infrared or other comunication. 3 looks like a ambient light sensor. and 4 is ofcourse the notice light.

to the forum! On the left the two holes you see are the proximity sensors. On the right the bigger one is the light sensor, and the one to the far right is the notification LED. Unfortunately there is no infrared sensor

Proximity Sensor? what is the deal with those?

[Corinacakes]

Probably TMI but here ya go lol

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor requires a metal target.
The maximum distance that this sensor can detect is defined "nominal range". Some sensors have adjustments of the nominal range or means to report a graduated detection distance.
Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.
Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings.
IEC 60947-5-2 defines the technical details of proximity sensors.
A proximity sensor adjusted to a very short range is often used as a touch switch.
A proximity sensor is divided in two halves and if the two halves move away from each other, then a signal is activated.

Lol thank you corinacakes! I just learned something this morning! I fully understand them now thank u

Welcome to the Forum, what a great way to introduce yourself, great picture and questions

[diemaster]

so if it's a proximity sensor then whats it sensing? is it used for the touch screen?

[tp76]

It senses when the phone is by your face while in a call and turns the screen off to conserve power, then when you move it away from your face the screen comes back on so you can interact with your device again

Blacks out the screen also to prevent "cheek dialing" (hitting buttons with your face while you're talking).
