They work great with any microcontroller using a single digital pin and you can even connect multiple. Since the raspberry pi has no adc analog to digital converter it cannot directly use an analog temperature sensor like the tmp36 making the ds18b20 a good choice for temperature sensing. One wire temperature sensors like the ds18b20 are devices that can measure temperature with a minimal amount of hardware and wiring. This i2c digital temperature sensor is one of the more accurate precise we ve ever seen with a typical accuracy of.

These sensors come in a small three pin package like a transistor and are accurate digital devices. The default resolution at power up is 12 bit. 374 these 1 wire digital temperature sensors are fairly precise 0 5 c over much of the range and can give up to 12 bits of precision from the onboard digital to analog converter.

These sensors use a digital protocol to send accurate temperature readings directly to your development board without the need of an analog to digital converter or other extra hardware. Open up file examples adafruit mcp9808 mcp9808test and upload to your arduino wired up to the sensor. In this lesson you will learn how to use a ds18b20 with the raspberry pi to take temperature readings.

This sensor is a little more expensive than the other waterproof version we have with a. Unlike the ds18b20 this sensor does not come in through hole package so we placed this small sensor on a breakout. Compared to the lm75 however the 11 bit adc in the pct2075 provides more precise measurements when compared to the lm75 s 9 bit adc.
