TEMT6000 Light/Lux sensor supported?

[burton666]

I just got a couple of TEMT6000 lightsensors from ebay and wonder if they can be used with esp easy? How do I connect/configure in that case?

I've got the same question. It works as "analog input", but it's not very sensitive. Without a light shining directly on it I get a reading of 0.

I recommend the use of a analog photosensitive resistor (photoresistor). I got some that I use around the house and though it is not giving you Lux it do give you a 0-3.3V input of the level of light. If I close my hand around the resistor the voltage drops to about 0.65V and for direct sunlight or a bright lamp the voltage is about 3.26V (32752 in formula, see below). I use the analog input device ADS1115 (which I use for other analog devices as well) and have this settings:


The formula gives me a percentage of about 18-20% at night (it will never hit 0% since it will always be some voltage over the resistor) and on an average day or lighting the percentage is about 82-85%. During the day the voltage rise is relatively linear and I will get values evenly from the lowest 18% up to highest 85%. I'm happy with the unit, it is cheap, reliable and easy to integrate. I will try to make a wiki page for it asap. Many units only have a digital out and a potentiometer to set the trigger level for the output but I prefer using a unit with also an analog out which gives you better control over the behavior. This is the unit in the pictures below. But I also got this one.

Anyone had a go at getting one of the TEMT6000 sensors working?

[Tommmii]

yes, i am :p

yes, i am :p

Hi

and how?
which settings did you use?

Thanks

It's an analog sensor so it gives a voltage that follows the brightness.

You may use the analog input plugin.

With a bare ESP8266 it might need a voltage divider as the input should be in the range of 0....1 V.
On WeMOS and NoceMCU this voltage dividere is already there in most cases.

i used it with an ESP32, in the end the TEMP6000 isn't very reliable.
I moved over to a MH LDR like this one : https://www.ebay.co.uk/itm/Flying-Fish- ... 2015870724
Much easier to connect, more reliable.
