SHT-20 Temperature & Humidity Sensor Modbus RS485 High Precision<\/h1>\n
\n
<\/div>\n
Description:<\/strong>
\nProduct adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensors, ensure the products with good reliability, high precision and interchangeability.
\nAdopt RS485 hardware interface (with the lightning protection design), the protocol layer compatible with standard industrial Modbus Rtu protocol.
\nThis product integrating MODBUS protocol with ordinary, users can choose communication protocols, common agreement with automatic upload function(Connect the RS485 serial interface mode tool by automatically output temperature and humidity).<\/div>\n
Product Highlights:
\nIndustrial products, high progress SHT20 temperature and humidity sensor, the RS485 communication;
\nStandard MODBUS protocol with ordinary at an organic whole, the user can choose communication protocol;
\nBaud rate can decide for themselves;
\nGeneral agreement with automatic upload function, upload speed can decide for themselves.<\/div>\n
<\/div>\n
