Features: The RS485 SHT30 Sensors Adapter Board is a cutting edges solution that seamlessly converts temperature and humidity data from the SHT30 Sensors into Modbus RTU protocol, ensuring compatibility with both new and old systems. This adapter board features a wide operating voltages ranges and supports up to 247 cascaded module via RS485, making it ideal for industrial applications. SHA9D01 is a new SHT30 RS485 adapter board, which can convert the temperature and humidity data of the SHT30 Sensors into Modbus RTU protocol and output it through RS485/TTL232. Suitable for engineers and technicians, this module is perfect for those involved in developing industrial systems, or any project requiring precise environmental monitoring. Ideal for diverse Environment, the SHA9D01 excels in applications such as indoor and outdoor temperature measurement, weather forecasting, and maintaining conditions in computer room. Specifications: Component:ABS Type:5V TTL232/12V RS485/5V RS485 Working voltages: 5V version: 3.7-5.5V; 12V version: 6-25V Working current: 5-7MA MODBUS RTU protocol, 03, 04 read commands, 06, 16 write commands. By modifying the 485 address, up to 247 module can be cascaded (more than 16 please use R485) Sensors: SHT30 temperature and humidity Sensors Temperature measurement ranges: -40-125℃ (Because the shell and wire is not resistant to high temperatures, please use it in the environment of -40-80℃) Humidity measurement ranges: 0-100%RH Accuracy: ±0.2℃; ±2%RH Size: Approx.3.9x2cm/1.54x0.79inch Package Includes: 1Pc Humidity Sensors note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
