Temperature and Humidity Sensor “PAL-Temp”｜Easy Visualization with Modbus and IoT Compatibility
Easy Installation and Integration｜Visualize Temperature and Humidity Instantly
PAL-Temp is a compact IoT sensor equipped with built-in communication functionality, capable of measuring both temperature and humidity. It supports Modbus RTU communication, allowing seamless integration with a wide range of upper-level devices. Key Features 1. Modbus RTU Protocol for High Compatibility By adopting the widely used Modbus RTU protocol, PAL-Temp offers excellent compatibility and can be easily incorporated into existing systems and equipment. 2. Simple Installation with Cable Ties Installation is completed simply by securing the sensor with cable ties at the desired location. This enables easy deployment even in systems that are already in operation. 3. Compact Design with Built-in Communication Integrating communication functionality within the sensor itself enables a compact and lightweight design. PAL-Temp can be installed flexibly without constraints on location. System Integration with PAL-Plus Unit By combining PAL-Temp with the PAL-Plus Unit, which includes signal conversion to Modbus TCP and power supply functionality, users can build monitoring systems that are both space-efficient and cost-effective. Related Products We also offer a lineup of current sensors such as:PAL-Plus / PAL-Plus High-Capacity Model These sensors are capable of measuring AC current and are equipped with built-in communication features.

What is the PAL series sensor that can do more than just measure?
It may look like an ordinary sensor at first glance... but it's actually different!! We have uploaded a page introducing the "PAL Series Sensor," which integrates communication functions into the sensor itself, allowing both "measurement" and "communication" to be completed with just this one device. | PAL Series Sensor Measurement Items | - PAL-Plus / PAL-Plus Large Capacity Version: AC Current - PAL-Plus typeE: Simple Integrated Electric Energy, Simple Power, etc. - PAL-Temp: Temperature and Humidity As electricity costs rise and efforts towards SDGs are strengthened, this product serves as an excellent stepping stone for "visualization," so please take this opportunity to check it out! Additionally, we also accept proposals for system configurations utilizing the PAL Series Sensors. If you have any concerns regarding visualization for your factory or equipment, feel free to consult with Hexacore.
