CO2 Monitoring

CO2 monitoring is common across industrial sectors and is often mandated by health, safety, or environmental regulations. CO2 levels are carefully measured to ensure healthy air quality, maintain optimal growing conditions in greenhouses, reduce energy consumption in HVAC systems, and safeguard product quality.

CO2 Monitoring Methods with TPS Devices​

Use a Third-Party Modbus Sensor​

AppBlocks and TPS devices offer strong support for third-party Modbus equipment, so almost any RS485 Modbus device can be connected to a TPS unit. Use the Module Tibbit #02 or #05 for RS485 and the Connector Tibbit #20 (or #21) for terminal connections. You will also need to power your Modbus device. Tibbit #05 has a low-power +5V output, which is sufficient for our Bus Probes, but other Modbus devices may have different power requirements.

For Modbus devices with power requirements higher than 5V, you may also supply your own power.

Pros:

  • Complete flexibility in choosing the Modbus CO2 sensor.

Cons:

  • You will need to manually configure the sensor’s Modbus registers and data conversion within your AppBlocks application.
