Function and purpose
The CAN sensor for temperature, humidity and pressure is a versatile digital sensor that measures pressure, humidity and temperature with high accuracy, making it a cost-effective solution for monitoring environmental parameters in various environments.
Each measurement parameter (pressure, humidity, temperature) is displayed separately in the Didactum web interface. This configuration allows for the setting of individual thresholds and the creation of event-driven actions such as notifications and alarms for precise environmental control.
In addition, the CAN sensor's ability to calculate the dew point (based on temperature and humidity) enhances its suitability for monitoring areas prone to condensation. The sensor supports the CAN bus interface, allowing up to 10–32 CAN devices to be daisy-chained. This simplifies the installation and expansion of monitoring solutions across multiple areas or systems.
This sensor is ideal for data centers, industrial applications, and other facilities where monitoring multiple environmental parameters is essential for maintaining optimal conditions.
1. LEDs: “RUN” (green) – indicates that the device is correctly connected to the main module. “ERROR” or “ERR” (red) – indicates an error; the connection to the main module is interrupted.
2. “Pressure, Humidity, and Temperature Sensor” – The sensor is located outside the housing to ensure better and more precise measurements.
3. “TR” – This switch must be set to “ON” (down) if the sensor is the last in the CAN chain. Otherwise, it must be set to “OFF” (up).
Example 1: A CAN sensor is connected to the main module via the CAN bus. In this case, it is the only and last sensor in the CAN chain. Its second “TR” switch must be set to “ON” (down).
Example 2: Five sensors or modules are connected to the main module via the CAN bus. The sensor is not the last sensor in a chain, but is located, for example, in the middle. In this case, the "TR" switch must be in the "OFF" (up) position.
Example 2: Five sensors or modules are connected to the main module via the CAN bus. The sensor is the last sensor in the chain. The "TR" switch must be in the "ON" (down) position.
4. "CAN" – Two equivalent digital RJ11-6P4C connectors for connecting to the master module, CAN sensors, or CAN extensions on a CAN bus with automatic detection.
