1-Wire
1-Wire (abbreviated to 1W or OW), is a communication bus system designed for low-speed data transmission, signalling and power through a single wire.
To improve reliability, Unipi 1-Wire devices are designed for the best possible seriality and stability. This is achieved by using four conductors (GND, VCC, DATA-IN, DATA-OUT) - this arrangement is used for 8-port hubs, 1-Wire temperature sensors and other products from the Unipi 1W product range
Temperature sensors
Unipi 1-Wire sensors
1W-T-IB on-wall sensor
- variant of the 1W on-wall temperature sensor
- an interior 1W sensor based on the DS18B20 chip
- suitable for measurements in range of -10°C/+85°C
- compatible with all Unipi 1W devices → 4-wire connection
- easy connection to Unipi PLCs
- possible connection through RJ45 connector via a suitable splitter/hub
- additional info and tips for the sensor and its connection available in the 1-Wire article
Examples of use:
- measuring indoor temperature for the purpose of control and regulation of heating, air conditioning, ventilation or heat recovery
Possible applications:
- all Unipi PLCs with 1W bus including Unipi 1.1/Lite
- Unipi Extension xG18 (with RJ45 connection)
- Unipi 1-Wire hubs or splitters (with RJ45 connection)
The on-wall sensor can be connected directly to the 1W terminal on Patron or Neuron controllers. Alternatively, you can use a suitable hub or splitter (requires adding RJ45 connector to the sensor's cable); this option allows for connecting multiple sensors to a single PLC. RJ45 connector can be also used to connect the sensor to older Unipi Patron or Neuron controllers, or to Unipi 1.1/1.1 Lite. Further info is available in the 1-Wire article.
1W-T-IB2 on-wall sensor
- redesign of the 1W on-wall temperature sensor
