4. Product Detail of Cabinet temperature and humidity sensor OM-TH-B901
Cable Connection Instructions for Cabinet Temperature and Humidity Sensor OM-TH-B901.
The OM-TH-B901 cabinet temperature and humidity sensor connects to the environmental monitoring host via an RS485 interface. Standard straight-through network cables are used to daisy-chain the sensors. Connect the data output port (usually labeled as the upper port) of the previous sensor to the data input port (usually labeled as the lower port) of the next sensor. It is important to note that, to ensure communication stability and efficiency, no more than 64 temperature and humidity sensors should be connected in series on a single RS485 bus.

7. FAQ
Q: Is the installation of the cabinet temperature and humidity sensor OM-TH-B901 convenient?
A: Yes, the installation is very convenient. We have designed two installation methods: one is to directly adsorb the sensor inside and outside the iron cabinet with two strong magnets, and the other is to install it on the wall, which can meet different installation requirements.
Q: How about the power consumption performance of the cabinet temperature and humidity sensor OM-TH-B901?
A: It adopts an ultra-low power consumption design, which can operate stably for a long time. It is suitable for scenarios that require continuous monitoring, and at the same time, it reduces the energy consumption cost.
Q: If the positive and negative poles of the power input are connected reversely, will it damage the sensor?
A: No. Our sensor has the function of preventing reverse connection of the power input. Even if the positive and negative poles of the power input are connected reversely, it will not damage the device, ensuring the safety of use.
Q: Can the position be adjusted freely after installation?
A: Yes. If it is installed with strong magnets, you can directly move the adsorption position of the magnets. In the case of wall-mounted installation, if you need to adjust the position, the operation is simple, and the required tools are also common, which can meet the needs of flexible layout.
