Designed for battery racks & cabinets
Lithium Ion battery energy storage systems such as UPS can be monitored 24x7 to detect gas venting events that preceed thermal runaway events.
The sensor is available in 2 different versions: daisy chained or standard.
Using just one base unit and one IP address, up to 16 daisy co2, voc and temperature sensors can be deployed inside your UPS batteries or other BESS systems.
When used in the standard non-daisy chained version, then up to 8 sensors can be connected using the optional EXP-8HUB.

No PC or Software Required
The InfraSensing sensors connect to the base unit (BASE-WIRED). The base unit is a standalone device that has its own IP address in your network. On its own it will monitor the sensor and trigger alerts via email, SNMP or optional SMS when needed.
There is no software or PC required for the sensors to run.
With our optional Monitoring Software you can centrally monitor sensors with trending and more. This is optional and not required.
Daisy Chained? Here's How It works.
The DAISY-STARTER sensor connects to the the base unit. Up to 16 additional DAISY-CO2-VOC-TEMP sensors can be connected to the DAISY-STARTER using simple RJ45 cables. This makes the device an ethernet based co2, voc and temperature sensor to detect gas venting issues from Lithium Ion batteries. Integrates with BMS platforms using the Modbus TCP protocol. Or with NMS systems through SNMP GET and SNMP TRAPS.
First venting or off-gas detection
with InfraSensing's Off-Gas sensor
Lithium ion energy storage systems have gained widespread popularity in recent years due to their high energy density and long lifespan. However, these systems also come with risks, including the potential for thermal runaway events. Thermal runaway occurs when the internal temperature of a lithium ion battery rises rapidly, leading to the release of gases and an increase in pressure. If left unchecked, this process can lead to explosions or fires.
One of the key ways to prevent thermal runaway events is through the use of sensors that can detect off-gases or first venting events. The best sensor for this purpose is a sensor that can detect both carbon dioxide (CO2) and volatile organic compounds (VOCs).
CO2 is a key indicator of thermal runaway events in lithium ion batteries. As the internal temperature of the battery increases, the cathode material begins to decompose, releasing CO2 gas. By detecting the presence of CO2, a sensor can alert engineers to the early stages of a thermal runaway event, allowing them to take action to prevent further escalation.
VOCs are also a reliable indicator of thermal runaway events. As the internal temperature of a lithium ion battery increases, it can release a variety of volatile organic compounds, including acetone, formaldehyde, and acrolein. These compounds are toxic and can pose a significant hazard if inhaled. By detecting the presence of VOCs, a sensor can help to prevent exposure to these dangerous gases.
In addition to detecting CO2 and VOCs, it is important for the sensor to be able to operate in a wide range of temperatures and environments. Lithium ion batteries are often used in a variety of applications, including electric vehicles, portable electronics, and renewable energy storage systems. As such, the sensor needs to be able to function effectively in a range of temperature and humidity conditions.
Overall, a sensor that can detect both CO2 and VOCs is the best option for identifying off-gases or first venting events in lithium ion energy storage systems. By detecting these gases at an early stage, engineers can take action to prevent the escalation of a thermal runaway event and reduce the risk of explosions or fires.
