Temperature Humidity Transmitter, RS485 SHT20 Sensor Modbus RTU Acquisition Module Transducer High Precision Monitoring Modbus

• Note: Users need to prepare their own ModBus debugging tool and RS485 debugger. Users needs to complete write code according to the communication protocol and commands if using the controller to receive data.
• Using Steps: 1>.Connect signal receiver such as Arduino to RS485 terminal. 2>.Input power supply at power terminal. 3>.According to the acquired data, the data is processed differently according to actual needs.
• Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, ensure the products with good reliability, high precision and interchangeability.
• Adopt RS485 hardware interface (with the lightning protection design), the protocol layer compatible with standard industrial Modbus RTU protocol.
• QUALITY ASSURANCE: To provide you with the highest quality assurance, if you are not satisfied with the product, please contact us.
