1-Wire

Intro to 1-Wire

1-Wire is a device communications bus system that provides low-speed data, signaling, and power over a single conductor. It’s similar in concept to I²C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments.

One distinctive feature of the bus is the possibility of using only two wires: data and ground. To accomplish this, 1-Wire devices include an 800 pF capacitor to store charge, and to power the device during periods when the data line is active.

Chipkin has developed multiple devices to facilitate 1-Wire communication. Our solutions read, log, convert, or push to could 1-Wire messages from a DS18b20 temperature sensor.

Our 1-Wire devices require minimal configuration and can be considered a ‘plug and play’ component of any network system. It’s ready to operate ‘out of the box’ and can be installed without an engineer’s approval.

Important: The serial driver uses an RS232 serial port to connect the 1-Wire network and a 1-wire to RS232 converter must be installed on the Chipkin Gateway.

Product Description

Chipkin™ 1-Wire™ Modbus® RTU/TCP, BACnet® and HTTP gateway is a protocol converter for 1-Wire DS18b20 temperature sensors. The gateway operates by reading the temperature data from the 1 or more DS18b20 1-wire sensors into an internal database. The values read from these sensors can then be read from Modbus® RTU/TCP, BACnet® and HTTP.

The gateway requires minimal configuration and can be considered a ‘plug and play’ component of any network system. It’s ready to operate ‘out of the box’ and can be installed without an engineer’s approval.

Product Description

Chipkin’s CAS-Bridge 1-Wire to Modbus TCP/RTU and IoT, monitors a series of 1-Wire temperature sensors and makes the data available to Modbus devices, as well as logging long-term trending data into the cloud. The CAS-Bridge operates by monitoring the 1-Wire temperature sensors and storing the values in an internal database. Then serving the temperature data as Modbus TCP/RTU values. When a value changes or a timeout occurs, the values are sent to an online dashboard for long-term trending and logging.

The CAS Bridge can be connected to your network with an ethernet connection or by connecting to a WiFi access point.

CAS Data Client - 1-Wire

Product Description

Chipkin™ 1-Wire™ Data Client connects to 1-Wire DS18b20 temperature sensors. The Data Client operates by reading the temperature data from 1 or more sensors. The data and transactions are logged into an internal database which are available and can be transferred to other computers and monitored by remote systems. Of course, this data is also available using an Internet Browser such as Google Chrome. Connection, device, and data parameters are configurable.

The Data Client requires minimal configuration and can be considered a ‘plug and play’ component of any network system. It’s ready to operate ‘out of the box’ and can be installed without an engineer’s approval.

Product Description

Chipkin™ 1-Wire™ Windows gateway is a protocol converter for 1-Wire DS18b20 temperature sensors. The gateway operates by reading the temperature data from 1 or more sensors and storing them inside a database. The values can then be read from Modbus® RTU/TCP, BACnet® and HTTP.

The gateway requires minimal configuration and can be considered a ‘plug and play’ component of any network system. It’s ready to operate ‘out of the box’ and can be installed without an engineer’s approval.
