I was about to launch a support request, before I found out by mistake that the description is wrong about the wire colours/pinout. When using the below config the sensors work fine. WHITE - DATA (Pin 2); RED - VDD/GND (Pin 1+3) Don't use the incorrect pinout as per the BG description above. This is the parasite power version, which is not as robust and extendable (distance) as the 3-wire "normal" version. Us this one instead if you would like the normal version Product ID 983801 - it is only slightly more expensive. http://www.banggood.com/DS18B20-Waterproof-Digital-Temperature-Temp-Sensor-Probe-1M-2M-3M-5M-10M-15M-p-983801.html The schematic shows how to correctly wire up the sensor. The photo is wrong (but according to the BG description). The waterproofness is yet untested, but hoping it is ok to put the sensor into water. All in all, a fine products once you know the pinout.
Great quality, good outside shell and works perfectly!!
I wirks vanno bene.
Good temperature reading sensor. Lacking information on the connection took me long time to find that the red wire is actually the ground and the white one is the data / Plus. data wire needs to be pooled up bu 4.7K resistor connected to 3.3 or 5 Volts.
Prodotto molto bello, fa il suo lavoro perfettamente. La spedizione è stata veloce e il prodotto era in buone condizioni!
Proprio come previsto, lavorare senza problemi.
It took me only 10 minutes to get this sensor connected to an arduino esp8266 controller, get software and see the outside temperature on my smartphone. Just one word for it: GREAT.
ricevuto per il tempo di stima poveri imballaggi.... borchie erano fuori scatola e in sacchetto di plastica laterale. più componenti sono piegati. la qualità del pcb non è all'altezza del marchio ancora non alimentato.. posterà più tardi per le prestazioni.
not the greatest but its alright...
