OMRON 2JCIE-BU Environment Sensor (USB Type) Serial Data Translator

npm install @candy-line/node-red-contrib-omron-2jcie-bu

OMRON 2JCIE-BU Environment Sensor (USB Type) Serial Data Translator node.

This node DOES NOT SUPPORT Bluetooth Communication Packets but DOES USB Serial Communication Packets.

Supported sensor values are as follows.

1. Illuminance (lux)
2. Temperature (degree Celsius)
3. Humidity (%)
4. Barometric Pressure (hPa)
5. Sound Noise (dB)
6. eTVOC (ppb)
7. eCO2 (ppm)
8. Discomfort Index (DI, Temperature-Humidity Index)
9. Heat Stroke (degree Celsius)
10. Spectral Intensity Value (SI Value in cm/s=kine, for small to medium scale vibration)
11. Seismic Intensity Scale of Japan (for larger scale vibration like earthquake)
12. Vibration Status (None, Vibration Detected, or Earthquake Detected)
13. Mounting Position (see below)

This node project offers nodes translating the raw packets into easy-to-use JSON objects and vice-versa.

With 2JCIE-BU out node, you can query sensor information by sending a command message object. You can set the LED color as well with the node.

With 2JCIE-BU in node, you can get a JSON object from a raw data packet in response to a command. The node supports Node-RED Dashboard Chart node data format, which means you can quickly plot the device sensor data with the Chart node without any data transformation (available for numeric data).

Example Flow

The bundled example flow provides the following demonstrations:

• getLatestSensorData inject node to send getLatestSensorData command
• getMountingOrientation inject node to send getMountingOrientation command
• getMountingOrientation inject node to send getMountingOrientation command
• set LED Color (Light Blue) inject node to send setLED command with Light Blue color number
• set LED Color Rule (Temperature) inject node to send setLED command with Temperature display rule

All outputs are shown on the debug tab.

Prerequisites

Software

The following node is required to send/receive data packets via USB serial.

• node-red-node-serialport node
• Linux FTDI Driver (ftdi_sio.ko)

Hardware

• OMRON 2JCIE-BU

Supported OS

• Linux

How to use

In order to use OMRON 2JCIE-BU, you might need some work as described below.

1. Add Product ID and Vendor ID to the FTDI Driver
2. Configure the serial port config node

Add Product ID and Vendor ID to the FTDI Driver

Make sure ftdi_sio.ko is installed on the linux box and insert OMRON 2JCIE-BU. Then Run the following commands in order to have the driver to detect OMRON 2JCIE-BU as a FTDI device. And /dev/ttyUSB[0-9]* will be available.

$ sudo modprobe ftdi_sio
$ sudo chmod 777 /sys/bus/usb-serial/drivers/ftdi_sio/new_id
$ sudo echo 0590 00d4 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id

Configure the serial port config node

After starting your Node-RED, configure serial port config node.

• Choose Serial Port (typically /dev/ttyUSB0)
• Set 115200 for Baud Rate
• Choose after a timeout of input-split condition (timeout mode)
• Choose binary buffers for the delivery type
• Leave default timeout to 10 sec (10000ms)

How to install

Node-RED users

Use Manage Palette dialog in the browser editor or run the following commands:

cd ~/.node-red
npm install @candy-line/node-red-contrib-omron-2jcie-bu

Then restart Node-RED process.

Uninstallation

cd ~/.node-red
npm uninstall @candy-line/node-red-contrib-omron-2jcie-bu

CANDY RED users

Use Manage Palette dialog in the browser editor or run the following commands:

cd /opt/candy-red/.node-red
sudo npm install --unsafe-perm @candy-line/node-red-contrib-omron-2jcie-bu

Then restart candy-red service.

sudo systemctl restart candy-red

Uninstallation

Manage Palette dialog should work for uninstallation as well as the following commands:

cd /opt/candy-red/.node-red
sudo npm uninstall --unsafe-perm @candy-line/node-red-contrib-omron-2jcie-bu
