[Introduction]:A remote control product that supports analog quantity following and control acquisition. It supports wireless Modbus RTU protocol in control acquisition mode. This product is highly easy to use, and users can easily and quickly integrate it into their own system to achieve remote control based on 433MHz wireless. The analog output of the receiving end can follow the analog input of the sending end. After being configured as two-way following, the analog output of the sending end can follow the analog input of the receiving end. The product is sprayed with three-proof paint, which has functions such as "anti-mildew", "anti-humidity" and "anti-salt spray".
