It measures temperature and relative humidity, transmitting data over an RS485 Modbus RTU interface, making it easy to integrate with PLCs, microcontrollers, SCADA systems, and data loggers.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between the SHT20 and the SHT20 with case options?\u003c\/h4\u003e\n\u003cp\u003eA: The bare SHT20 SMD module is ideal for custom PCB integration or projects where you supply your own enclosure. The SHT20 with case version comes in a protective housing, making it suitable for deployment in environments where the sensor may be exposed to dust, mechanical contact, or general handling — providing added durability without extra assembly.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this sensor compatible with Arduino, Raspberry Pi, or other microcontrollers?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The RS485 Modbus RTU interface is widely supported across platforms including Arduino, Raspberry Pi, and ESP32 using standard RS485-to-TTL or RS485-to-USB adapters. The Modbus RTU protocol is well-documented and straightforward to implement with commonly available libraries.\u003c\/p\u003e\n\u003ch4\u003eQ: What communication protocol does this sensor use?\u003c\/h4\u003e\n\u003cp\u003eA: This sensor communicates using the \u003cstrong\u003eModbus RTU protocol over RS485\u003c\/strong\u003e — a robust, industry-standard serial communication method that supports long cable runs, noise immunity, and multi-device networking on a single bus.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
