The DS18B20+ is a handy, 1-wire compatible temperature sensor, ideal for interfacing with the PICAXE!
Description [Hide]
The Dallas Semiconductor DS18B20+ is ideal for interfacing to a microcontroller, especially if it uses the '1-Wire' interface which allows looong distances between sensor and microcontroller (200'+!).
It is often used with the PICAXE microcontroller, which has the built-in function "readtemp" to communicate with this device.
The DS18B20+ features:
- 1-Wire interface
- Unique 64 bit serial code so many devices can share same data line
- Data line powered from 3 to 5.5V
- Measures -55 to +125°C (-67°F to +257°F)
- ±0.5°C Accuracy from -10°C to +85°C
- Resolution is user-selectable from 9 to 12 bits deep. That means resolutions of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C!
- Converts temperature to 12-bit digital word in 750mS (higher accuracy takes more time to measure!)
Packaged in a TO-92 (transistor-like) package, all you need is 2 wires - ground and DQ (I/O & power), or you can use the Vdd line to give it regular power input.
