- the most inexpensive variant of 1W temperature sensor
- digital waterproof sensor based on the DS18B20 chip
- size of the metal sensor casing: 6×30 mm
- suitable for temperature measurements in range of -10°C/+85°C (from -55°C up to +125°C with reduced accuracy)
- compatible with all Unipi 1-Wire devices → 4-wire connection
- easy connection to Unipi controllers using an RJ45 connector with a suitable reduction or splitter
- more info and tips regarding sensor connection are available in the 1-Wire article
Examples of use:
- measuring indoor or outdoor temperature for the purpose of heating regulation
- measuring temperature of liquids stored in tanks (several sensors can be placed on various levels to improve the accuracy)
- measuring temperature of liquids in pipes
Possible applications:
- all Unipi PLCs with 1-Wire bus, including Unipi 1.1/1.1 Lite
- the Unipi Extension xG18 module
- the Unipi 8-port hub or the 2-port splitter
If you want to connect the temperature sensor directly to Patron or Neuron controllers, you can do so by cutting off the connector and connecting the sensor directly to the PLC's 1-Wire terminal. Older variants of Unipi Neuron and Patron controllers, as well as Unipi 1.1/1.1 Lite, support a direct connection as they feature an RJ45 port. Further info is available in the 1-Wire bus and 1-Wire sensor connection article.
