Ordered a DS18B20 temperature sensor on Amazon, thinking I could use this on the Arduino.
- DS18B20 Temperature Sensor
- 4.7K ohm resistor
- According to amazon, the output leads: red (VCC), yellow (DATA), black (GND).
- According to espruino, the values are red (vcc), white(data), black (ground) or red(vcc), yellow(data), green (ground).
- According to the real world, the output leads are red (VCC?), green (DATA?), and black (GND?).
- Find the 1 wire address
- hacktronics 1 wire tutorial
- one wire at pjrc
- Dallas temperature control library
- hobbytronics: briefest code example using dallas + onewire
Sadly it looks like either I cooked it or it is faulty. Could not get a reading, raw, or address-based response. Ordered some more from another dealer to compare.
