The DS18B20 is widely used 1-Wire sensor in TO-92 package.
- Power supply range is 3.0V to 5.5V
- Measures temperatures from -55°C to +125°C (-67°F to +257°F)
- ±0.5°C accuracy from -10°C to +85°C
- Converts 12-bit temperature to digital word in 750 ms (max.)
- Can be powered from data line
UniPi temperature sensor
The UniPi 1-Wire temperature sensor is equipped with RJ45 connector, so it is easy to connect to UniPi Neuron controllers and UniPi 1-Wire hub. In order to connect the sensor to UniPi Axon, you have to cut off the connector, put on the ferrules (see wiring guidelines) and screw it to the Axon's 1-Wire connector according to this pinout
The sensor introduces a 4 wire connection for better reliability of larger network, which can be converted to 3 wire version for simplification.
