Incubator Monitoring Wireless Temperature Monitoring

In Vitro Clinic Uses Accsense

ONLINE  —  CAS DataLoggers provided the automated incubator Accsense Wireless Current Data Logger monitoring and alarm system for an in vitro fertilization clinic which needed a wireless setup to monitor and alarm several double stack CO2 injection incubators.

These medical incubators were used for embryonic implantation stage of the in vitro process as opposed to long-term storage. Staff needs to maintain the incubators at a constant temperature of 37 °C (99 °F) and a relative humidity of 99%.

Each incubator is equipped with an external CO2 tank which lasts about a month before needing to be replaced. Sensors are used to determine the CO2 levels inside the incubators to keep them within acceptable limits (about 5% concentration).

However, sensor accuracy is vulnerable to temperature and humidity fluctuations within the incubators caused by opening the doors. Therefore this complex setup required an automatic system to monitor and alarm temperature, humidity, and CO2 in real time to alert staff of unsafe levels and prevent any losses.


After taking their call, CAS visited the clinic to install an Accsense system consisting of three Accsense Wireless Current Data Loggers attached to the side of each double stack unit. All the data loggers communicated with an Accsense B1-06 Wireless Data Logger Gateway which was mounted on a nearby wall.

Offering multi-input continual monitoring, each wireless datalogger featured six 4-20 mA inputs which were connected to two external temperature and humidity sensors along with two external CO2 sensors to cover each double stack incubator.

All the necessary parameters in the incubators were covered by this arrangement.

Two external 24 V power supplies provided power to the probes. Each data logger’s wireless range extends out to 90’ indoors without obstructions and can also act as a repeater for other logger signals. CAS DataLoggers also provided the clinic with NIST-traceable calibration certificates for a competitive cost.

The wireless gateway uses built-in 10/100BaseT Ethernet to communicate to the Accsense cloud server. The cloud server eliminates any heavy IT burden often found with local server installations.

Diagnostic LEDs provide a clear status indication. In the event, the gateway can’t be reached, individual pods store up to 255 data points until a connection is restored, while the gateway’s 1900-point data buffer further ensures continual data integrity.


Each logger’s two digital inputs enable monitoring of the door opening and closings including counting of open/close cycles. User-configured alarms also monitor for unsafe temperatures, humidity, and CO2 levels and will send email, pager or phone warnings to multiple designees whenever an alarm triggers.

Cloud-based data storage and reporting enable effective monitoring of each pod monitors and logs data, giving staff the ability to view and remotely access data in real-time. The wireless gateway sends all this data to the secure Accsense cloud server.

This data can also be downloaded as a CSV file for use with many database applications or for custom reports.

Additionally, the clinic’s online Accsense account gives instant access to charts showing all measurement history with ranges as narrow as 5 minutes or as wide as 90 days.

The account also features an interface with a dashboard showing the most recent measurements from all sensor pods. Clinic personnel now retrieve all readings for offline analysis, login to access reports and graphs, and can modify the system setup from anywhere they’re connected to the Internet.


Now the clinic relies on Accsense to notify employees when any of the incubator environments are compromised.

Whenever this happens, the system makes voice synthesized alert phone calls until staff designees respond and take safety measures. Likewise, the system sends all readings to the cloud so that regulators have proof that best practices were followed.

Accsense was particularly cost-effective for this unique application, covering 6 monitoring points and 3 separate values with just 3 data loggers and a gateway.

Accsense can be used for reliable incubator temperature monitoring solution or as part of an incubator validation protocol in clinical or research environments.
