RLE Technologies WIFI-CO2 Wireless WiFi Temperature and Humidity Sensor User Guide
Included with the WIFI-CO2
WIFI-CO2 device – includes two 3.6V lithium batteries
Available from RLE, sold separately
USB-A to Micro B cable, used for configuration
Computer with a terminal interface (CLI)
Technical Support Note:
This sensor is compatible with RLE’s WiNG-MGR. For the sensor and WiNG MGR to communicate correctly, the WiNG-MGR may require a firmware update:
|Device||Minimum Required Firmware|
Each sensor is equipped with two 3.6V lithium batteries which should be replaced as needed. Once the protective battery tab has been removed, the average battery life is up to 5 years at the default transmission interval. Battery life varies based on WiFi signal strength, transmission interval, and access point performance. Sensors will not operate with alkaline batteries – make sure the batteries are replaced with two 3.6V lithium cells. Safely dispose of old batteries.
The sensor is shipped with a battery pull tab in place which turns the device off. To activate the sensor, remove the protective tab to engage the batteries. Turn off the sensor by re-inserting the tab or removing the batteries. Any time the sensor is shipped, it should either be turned off or placed in a shielded container to prevent interference that might cause shipping problems.
Once the sensor is activated, put the lid back onto the sensor enclosure.
Each WIFI-CO2 sensor needs to be configured to communicate on your wireless network. Use a USB-A to Micro B cable and a computer with a terminal interface (CLI) to configure the sensors.
Each WIFI-CO2 sensor must be configured for its environment during deployment. The sensor will not operate properly until all steps of this initial configuration procedure are completed:
There are several alarm and alert patterns and colors programmed for the LED. The LED is almost always off during standard operation and is primarily active during sensor configuration and reset sequences.
The sensor’s push button is located next to the LED and is used to reset the sensor to its original factory settings.
If you’d like to reset the sensor, it must be connected to a computer via the USB cable. Push and hold the button for 10 seconds. A countdown will be displayed in the terminal emulation software, and the LED will flash purple to indicate the sensor is being reset. Once the reset is complete, the sensor LED will glow blue.
You can also press the button once to send a single packet once the sensor is configured on your network and the USB cable is unplugged from the sensor.
These basic commands are available via a computer’s Terminal Interface (CLI):
|Blank||Print a list of all commands|
|C||Configure a wireless network|
|S||Set wireless SSID|
|P||Set wireless password and device password|
|A||Set wireless authentication type|
|D||Turn DHCP on and off|
|I||Set IP address (if DHCP is disabled)|
|N||Set netmask (if DHCP is disabled)|
|G||Set network gateway (if DHCP is disabled)|
|M||Set IP mode (IPv4 or static IPv6)|
|B||Set BMS or WiNG-MGR IP address to receive packet|
|U||Designate where UDP port packet will be sent|
|W||Set wake interval|
|Z||Set group ID (will be transmitted with packet)|
|F||Configure sensor-specific settings – see details in table below|
|V||Display advanced settings|
|X||Transmit a test packet|
The following sensor settings are accessed through the F option on the main menu:
|Sensor Settings Commands||Description|
|Blank||Print a list of all commands|
|A||Set altitude offset (Necessary for proper calibration)|
|E||Enable or disable bi-weekly auto-zero|
|T||Take sensor readings (CO2, temperature, humidity)|
|V||View sensor diagnostic and debugging information|
|X||Exit and return to main menu|
|0||Status Flag (U16)||Protocol Version (U8)||MAC Address (U8)|
|32||MAC Address (U8)|
|64||MAC Address (U8)||Sensor Type (U8)||Packet Counter (U16)|
|96||Group ID (U16)||Battery Voltage (U16) Unit: centivolts |
Divide unit value by 100 for combined total voltage of both batteries.
Example: Data value = 635 635 ÷ 100 = 6.35
Total voltage of two batteries = 6.35V
Battery life guidelines:
> 6.0V = Good
> 5.8V = OK – replace soon
< 5.6V = Poor – replace immediately
|128||Version Major (U8)||Version Minor (U8)||RSSI (U16)|
|Data 1 |
Data Type: UINT16 Description: CO2 Unit: PPM
Example: Data 1 value = 818 CO2 Level = 818 PPM
|Data 2 Data type: INT16 |
Description: Sensor temperature Unit: deci °C
Divide unit value by 10 for temperature reading.
Example: Data 2 value = 230
230 ÷ 10 = 23
Temperature = 23°C
|192||Data 1 |
Data type: UINT16 Description: Sensor humidity Unit: deci %
Divide unit value by 10 for humidity reading.
Example: Data 1 value = 435
435 ÷ 10 = 43.5
Humidity = 43.5%
|320||Reserved||Packet CRC (U16)|
