5X / 10X DS18B20 Programmable Resolution 1-Wire Interface Technology Single Bus Temperature Sensor Analog Digital Output TO-92 Package for Arduino Raspberry Pi Microcontroller (10)

The circuit diagram on the manufacturers website that includes a UNO is incorrect! If you hook it up this way it will fry the part in minutes.The proper pinout (when viewing the lettering on the product) is (1 - left) +5V, (2 - center) analog out, (3 - right) GND. Also their example Arduino code says that it is displaying Celcius but it is actually Fehrenheit.Otherwise, the product works well, though it takes 15-20 seconds to adjust to even minor temperature changes.

they work great as long as you know the pinout. Get this mixed up and wonder why nothing is working, grab the sensor and burn the &^%$# out of your fingers because you have the VCC/GND reversed. Well pay attention.

These are small, light, and reliable. The interface is simple, direct read, no serial circuit needed. The electronics are encapsulated, useful in dirty or humid conditions. The current draw is small. They are accurate, linear, and fairly quick to react to temperature changes. Plus that, the company offers a complete data sheet for the device.MAKE SURE YOU READ IT. There are a lot of misleading pieces of info around about the pin connections. If you hook Vcc and ground backwards, you will fry the device, burn your fingers, and possibly damage or destroy your Arduino / Pi / etc. Make sure to look at page 1 of the datasheet before you start.

My sensors seem to be exactly backwards from what was described in their manual. Wondering why the reading was saying numbers around 500, I thought I had to do some interpretation/calibration. So, just to test if the number went up when it is warmer, I grasped the sensor with two fingers. Immediately time slowed down to a halt as I felt the surface of the sun on my fingertips. My breadboard is melted now. Watch to see if the sensor is flipped before touching.

Have had to reset whole microcontroller circuit and sometimes reload program. (On program reload I accept much of that is my fault but I have had working code run for days and the sensor data is skewed from actual. Reset and reload program will fix.Rig is not at fault current project and program has ran a month on same rig I tested initially. Have bee running it on a mega2560 chip with good results. You can see some of the error reads in the image of the terminal output.-d²

Happy with TMP36; sensing values are consistent. Bear 2 points in mind:1.- Place the TMP36 on the breadboard with the lettered side facing the Arduino board, and the rounded side facing away. Connect the left pin of the lettered side to 5Volts, the midle pin to an analog pin, and the right pin to GND.2.- The TMP36 is very sensitive. For accurate sensing, use breadboard jumper wires (long pieces) to connect all TMP36 pins. Avoid wiring with cables that have a black cap surrounding the tip; sensor may not return accurate voltage values.

Low enough current fraw to turn on with a bjt so they can be switched on with a GPIO. They do take a minimum 10 seconds to get a good reading.

Arduino project part and they work great

Used to sense the temperature of air and central heating pipes for Raspberry Pi application. I used 10 uF bypass capacitor and resistor to minimise noise as described in datasheet. Recommended.

ottimi sensori della temperatura, utilizzati per una ,mini stazione di rilevamento da interno, ovviamente la precisione è proporzionata al prezzo dell'articolo ma comunque la temperatura rilevata si discosta poco da quella reale, comunque funzionale e non ingombrante come altro sensori. consigliato

prodotto ok affidabili.

super

Ho ricevuto due pezzi invece di cinque.
